Do you know why copper wires are used to make water pipes?

Copper is one of the most used metal in making water pipes around the world. And copper has its own reasons for leading on top. Copper Pipes is durable compared to other similar metals and can be recycled time and again. Because it can be recycled, using copper wires are the best metals to be used for water pipes, because they won’t impact the environment as much as other non-recyclable metals would do. The cost initially invested in the copper water pipes can be huge but their durability makes them long lasting and a fair deal.

If you are still looking for more reasons to understand why copper wires are used to make water pipes, here are to name a few:

• Considerations: Plumbers prefer working with copper wires because they are malleable and light in weight. They are also easy to fit onsite and are easier to customize. It requires minimal tools and less efforts comparatively, to fit a copper wire. It is definitely easier and quicker to install compared to other metal pipes.

• Significance: Copper wires can resist corrosions in areas with neutral-pH water. They do this by forming a protective thin coating inside the pipe. This helps in keeping the structural integrity intact. This also allows a smaller-diameter pipe to do maximum consistent water flow. These factors make copper not just one of the most durable and reliable metal for pipes, but also one of the lowest cost metal with better value.

• Benefits: Everyone knows, copper is a good conductor of electricity and heat and this makes it the most preferred metal. This property of copper allows the copper pipes to get warm during exposure to hot water and stay warm for long. This helps to keep hot water at a consistent temperature when it travels through the house. The conductivity of copper makes it the perfect choice for radiant heating systems which pump hot water through the floors to heat a room.

Here’s everything you need to know about copper wires!

During our school times, we have studied about a lot of metals that are used for various purposes. Copper is among them. Copper, as we all know is a soft, ductile, and a malleable metal. It has a high electrical and thermal conductivity and we know it is highly used as a conductor of heat and electricity. Also, it is used as a building material, and sometimes as a constituent of various metal alloys. But is that all? Of course, not. So, let us understand it more.

Why is copper used in electricity wiring?

Copper has incomparable current carrying capacity which has set high standards of conductivity. Due to its high conductivity and efficiency compared to other metals, it is not only used in electricity wiring, but has also become an international standard to which other metals are compared.

What are the main uses of copper wires?

Copper, as said above, has excellent conductivity power and thus is highly used in electrical motors and generators, for electrical wiring, and in electronics such as Televisions, Radio sets, air-conditioners, vehicle radiators and home heating systems, etc. In other words, Copper wires are mainly used in power transmission, power generation, power distribution, electronic circuitry and telecommunications.

What are the properties of copper wires?

Copper wires have some great unsurpassed properties that are rarely found in other metals and thus these are highly used. It includes, tensile strength, ductility, creep resistance, corrosion resistance, coefficient of thermal extension, thermal conductivity, ease of installation and solderability, etc.

Tasks related to installation of wires and dealing with other repairing and construction work for electronics, are best done by the experts, isn’t it? But finding the expert and the best possible way to get things done, is certainly your job. In such a competitive world, the numerous companies out there will try to woo you with some offers, great deals (or at least will seem like one), or maybe discounts, etc. but which out them are real? Don’t worry Ganpati Engineering is one place where you’ll get it all.

Top 5 Reasons why Copper Rules the Medical Industry

Medical industry has advanced from being a service-driven sector to a technology-driven industry. In the last 25 years, more than 10,000 innovations in medical and surgical instruments have led to significant reduction in mortality. Surgical instruments and diagnostic tools now come with precision that helps the operator to make the right decisions.

Despite the rise of titanium and platinum instruments, copper wires and plates continue to rule the medical industry.

Here are the 5 reasons that make copper wires so popular and reliable.

1. Zero bacterial infection

Copper wires are used to tie up joints and bones fractured due to high impact. Due to interaction with blood and moisture, there is always a risk of being inflicted with internal infection. Once sutured, it is difficult to open up the wounds again and re-attend the infected site. That’s precisely the reason why medical industry prefers high quality bare copper wires to reattach joints and bones.

2. High corrosion resistance

Internal rusting has two downsides. One, rusting makes the material weak for use. Secondly, it can lead to secondary infection. Use of copper wires removes these chances by 99.90 percent. High corrosion resistance offered by bare copper wires as well as alloyed copper wires ensure longer shelf life and durability.

3. Disposable and hygienic operations

Irresponsible needle use is the leading reason behind diseases. Diseases and infections can be caused due to secondary transmission of virus. This is where copper wires are rated way higher than other metals.
Copper wires are drawn into thinnest of needles with size varying from 5 mm to 13 mm. They are hygienic and attract no risk of infection. However, they are still used just once to avoid the risk of AIDS-HIV/ Hepatitis. Disposable syringes made of other materials are hardly recyclable and also cost much higher compared to the bare copper wires.

4. Unbeatable strength

Sports persons have a tough time saving their jaws and teeth. Copper braces and shielded copper wires provide definitive shield against high impact blows, corrosion due to saliva and also against the food. Copper wires in orthodontics are rated as the best in the medical industry. Sportspersons involved in boxing, rugby, football, hockey and also gymnastics rely on the bare copper wires orthodontic sets to keep their teeth safe and intact.

Thanks to their compatibility with other metals, alloys and organic fibers, orthodontic copper wires are available as—

Traditional metallic braces
Ceramic copper wired braces
Invisible lingual braces

The braces made of copper wires can withstand the effects of high temperature foods as well as carbonated cold drinks. They also reduce the risk of infection inside the mouth by 99 percent, due to their anti-bacterial and anti-fungal properties.

5. Easy penetration

This is the reason why Copper wires are used as intrauterine devices. Copper-T wires are considered as the safest and cheapest mode of contraception for females. The long-acting reversible contraception device comes with a failure rate of less than 0.08 percent. While copper wires are easy to penetrate, they don’t interfere with the sexual experience in any way.

A look at Top 4 Configuration of Stranded Copper Wires

Let us take a look at the differ configuration of stranded cooper wires.

1. True Concentric

These wires have a central copper wire. This core is surrounded by a successive layers of alternately arranged strands with the length of each layer slightly larger than the successive layer. The lay direction is established by the twisting of the machine during the stranding process.
The lay length in these wires keep reducing as the layers are added to the inner strands.

2. Equilay

Also called as equally laid concentric cables, these stranded types of copper wires have helically arranged strands. The lay length is consistent unlike that in the true concentric strands. Rest of the features are same as that of its true sibling.

3. Unidirectional 

This is a special case of concentric stranding where the helically laid strands are laid in the same direction with increasing lay length. These configurations allows the conductor cable to be laid in a tight geometry with lowest tolerance for diameter variations throughout the length of the wire.
The wires are preferred for motors and transformers featuring in the high torsional simulations, like in automated production lines or in robotics. In short, it is easy to classify unidirectional stranded wire cables as “Robotics Cables”.

4. Rope

Rope stranding is also a type of stranded wire configuration where the strands of copper wires are arranged in a circular manner mostly comprising of 7 or 19 members. It is witnessed that the Rope stranding has the highest twisting and bending flexibility compared to other stranding mechanisms. The advantage of using Rope stranding is that the manufacturer can add successive layers of strands without compromising on the diameter tolerances, already fixed for the appliance.

Identification of Stranded Cables

Stranded cables are extensively used as Power cables and Submersible winding wires. Depending on the laying of the wires, they are classified into three families.

• Class B Power Cables
• Class C with higher flexibility quotient than Class B stranding
• Class D with highest flexibility, accommodating additional layers of stranding within diameter tolerance limits

Another classification of the stranded copper cables is done on the basis of rope layout and the kind of application it is employed in.

• Class G covering the Portable winding wires
• Class H Enamelled copper wires with polyesterimide insulation for better flexibility
• Class I cables for motor leads
• Class K stationary cables for cord and winding of No. 30 AWG wires
• Class M No.34 AWG Constant service

There are other braided varieties of the copper wires that more or less add extra level of robustness into the configuration. They are:

• Loaded twisted pair with extra inductance, used in load coils
• Bonded pairs
• Ribbon cables for connectors and printed circuit boards

Litz Wires

Extensively used in electronic circuits, Litz wires are insulated strands of thin copper wires woven or twisted around each other to reduce the Skin Effect and Proximity Effect.

They are used in transformers and inductors operating at high frequencies.

Copper Wire Manufacturing for Industrial Applications

Copper is a very useful metal considering its wide scale application. It is used extensively as a manufacturing material in the production of engineering equipment, electrical circuits and medical utilities.

Annealed copper wires are softer and flexible enough to be extruded into even thinner wires. This is when they are best suited to undergo the process of coating. There are different types of coating done on the copper wires.

Coating of wires

Copper wires are covered in a variety of materials like plastics, rubber polymers, resins, and varnishes. Depending on the purpose, the material, thickness and the life of the insulator can be decided. Copper wires are insulated using the following methods.

Single cable

When the copper wire is single and has only one cable running inside the insulation channel, it is called a solid bare copper cable.

Co-axial cables

Two or more copper wires are wrapped in a concentric manner to give rise to a structure called coaxial cable. The two coaxial wires are separated by an insulation medium like resin or paraffin wax.

Taped wires

Two or more strands of the bare copper wires can also be tapped together using preservative materials like lead, aluminium sheaths or steel tapes. The taped wires are precursor model to the heavier stranded copper wires that are manufactured using disks and bobbins to derive huge spools of stranded copper wires.

Stranding of wires

Stranding in bare copper wires is a very important process. The flexible cables are twisted into a pair of coupled wires, much like coaxial wires. There are 10 different insulation codes for industrial applications, which often vary from one country to another. The insulated copper wires can be combined in more than 25 different ways to form the various categories of stranded copper wires.

Use of stranded copper wires

The engineering and metallurgical property of stranded copper wires are definitely better than the other types of copper wires. They are annealed, insulated and paired for better results. They are used in;

• Multi-circuit electrical boards

• High resistance industrial applications

• AC line servicing

• Musical instrument cables

• Machine cables and ropeways

• Control cables

Braiding of wires

Braided copper wires are advanced siblings of the stranded wires. When more than two types of copper wires are combined in the form of multiple strands, it is called as a braid. The Braided Copper wires have higher range of applications than the solid cables as well as the much closer variety, the Stranded ones.
Braided copper wires are flexible as well as sturdier than the stranded copper wires due to their multiple stranding. Braiding of copper wires into a bundle ensures higher break resistance and strength. However, the cost of manufacturing the branded copper wires also increases as the number of strands in it increase.

Testing and transportation

Each strand of copper wires has to be tested for safety and performance. Any failure in a single item could result in the loss of the entire stock. The most common method to test the physical strength of the copper wires is to perform a High-Voltage Test after doing Core-to-Sheath test. The electrical integrity is then checked with random scales measuring the resistance, capacitance, unbalance and electromagnetism.

A look at the Significance of Armoured Cables in Electrical System

You must have come across armoured cables several times in the context of wiring. However, you might not be very familiar with the concept associated with it. At the same time, it is also crucial for you to know its significance in the electrical wiring systems. Therefore, in this article, you will find more information on these cables and the purposes they serve in different applications. Accordingly, you can make your move in the best way. Some of the popular types includes:-

1 Al PVC Strip Armoured Cables
2 Cu PVC Strip Armoured Cables
3 Cu XLPE Wire Armoured Cable

What are these cables?

Armoured cable can be referred to as a power cable, which is usually made by assembling two or more electrical conductors. These electrical conductors hold each other tightly in an overall sheath. It comes with high protective covering so that it can be easily used for the purpose of transmitting electrical power from one point to another. It can greatly serve the purpose of underground needs of wiring. The installation of these cables might be rightly followed as a source of permanent wiring within the buildings. At the same time, they can run overhead or buried in the ground. At times, they can be left unexposed without the threat of any damage from the extremes of weather. These cables are available both as single conductor cables as well as multi-conductor cables.

In a more precise term, it can be said that the armoured cables are electrical cables that do not come with galvanized or stainless steel wrapped over the conductors for carrying out insulation. They are often coated with plastic sheaths in the outward area for supplying the main distribution and buried feeders.

The Significance Of These Cables:

Prior to using them, it is crucial to understand the significance of these cables. These are highly significant because of the immense amount of protection they offer. Consequently, it makes the process of electric transmission less risky. At the same time, it often acts as one of the major circuit protective conductors providing adequate amount of earthing to the equipment that is supplied by the cable.

Things To Know On Its Earthing:

In this context, it is crucial to note that the earthing capability of the wire has been in debate. A single cable does not come with a ground wire and the sheath is used only for the purpose of protection. Hence, it is always recommended to earth either one or both the ends of the cable. If both the ends are grounded, circular current pattern can flow between the armoured cables. Grounding only one end means allowing bleeding of voltage. The voltage might be induced in the sheath without creating any form of circular current.

At the same time, many are not aware that single cored cable does not contain any magnetic field from other two phases. When there are three phases in a cable, the magnetic field is zero. In a single core, there is no need to go for any cancelling effect, and the voltage is induced in the armour by the magnetic field.

Understanding The Difference Between Bare Copper Wire & Tinned Wire

In today’s date, copper is widely used as a metal in wide varieties of applications. However, based on the nature of the application for which copper is used, the nature of the metal used will vary. In some cases, bare copper wire can serve the purpose of the application, while in some others it has to be tinned. Asking which one is good will not gives any specific guarantees regarding the performance. There are good bare coppers and bad tinned wires and vice versa. As mentioned, it will largely depend on the purpose of the application, as a whole.

Bare Versus Tinned:

 

There are several controversies and opinions regarding the nature of the copper wire for different applications. Well, it is true that fresh and new bare wire made of copper can perform excellent, but at the same time, it can even oxidize quickly than the tinned ones. This in turn leads to the degeneration of the electrical performance.

As the metal is thinner, the chances of oxidation are more, and this in turn will create an impact on the application. In such a situation, it is often thought that tinned copper wire is an easy and effective way of keeping the conductor wire from getting oxidized. When copper is oxidized, it turns green, which in turn becomes a semi-conductor. This is definitely bad for good conducting bare copper wire.

There are two ways of preventing the process of oxidation. Something might be put over the metal to prevent air from reaching the surface. After all, air contains moisture, and a slight amount of moisture is enough for oxidation. When there is no air, there is no oxide, and hence no corrosion. Soldering wire can often help in sealing the copper. On the other hand, another way to prevent copper from getting oxidized is putting a layer of tin on the copper. Consequently, even when the insulation is stripped off, air will have a lesser chance to enter and cause the formation of copper oxide.

Problem With Tinned Wire:

However, tin layered copper wire also shows problems in the course of time with the increase in the frequencies of the wire. When the entire conductor is used, the tin layer can protect it. However, as frequencies go high, the amount of conductor used is less. Consequently, the tinned layer becomes prominent and affects the performance of the conductor.

It is important to remember that tin has almost about seven times the resistant capacity of copper. Therefore, if any application at 1MHz or higher should not contain any tinned coating. On the contrary, bare copper wire is ideal for the situation. This implies that video cables, category data cables or digital audio cables should be made of bare copper without any tinned coating on it. This is because they are used for high frequency applications. The tinned copper wires are usually preferable for low frequency applications, and they will tend to last longer.

Hence, understanding the application frequency is crucial in selecting the type of wire.

How To Bend Your Copper Pipe?

There are several reasons for which you might have to bend copper pipes. Even though several types of piping are available today, many people still prefer the traditional pipes made of copper. These can be used in behind walls and are available in the forms of rolls. If you want, you can mount them on the surface of the wall or bend them, as per your needs.

In fact, you might not be aware that there are several ways through which you can bend your copper pipes. Every time you may not require specialized plumbing tools for the same. Here are some of the specialized methods that you can follow in order to bend the pipes. 

The useful tools for this purpose are:

• Blow torch,
• Dry sand and funnel
• A vice
• Bucket of cold water
• Pipe benders
• Pipe bending springs
• A square to check the angle of bend.

Make sure that you always use protective gloves and safety glasses while carrying out this function.

Support During Bending:

Supporting the copper pipes during the bending process is essential in order to prevent them from getting collapsed or pleat. Make sure that regardless the method you follow, you support the pipe in some way or the other.

Using blow torches-

This is required in order to bend the tubing. You will have to solder the pipes so that bending is easily managed up to the desired temperature. However, if you have lots of pipe work to do, going for an oxy-acetylene torch will help in effective heating of the pipes to the point that they will bend the pipes.

Using pipe benders-

 

These are designed as per the sizes of the pipes. If you have different shaped pipes, you will have to invest in an entire set of pipe benders. This in turn will make the work accurate, easy and you will not need any kind of heating.

Using Pipe bending springs-

You can heat the copper pipe until it is red hot and achieves the length of the bend. The pipe can then be slipped into the spring easily so that you can bend the pipe supported by the spring. It is here that you will need to cool the pipes with a bucket of cold water. These springs can be less expensive than the pipe benders. Moreover, they can be stored and transported easily from one place to another. It is one time investment and you can use it whenever required.

Using sand for support-

You can bend copper pipes even with sand. Make sure that the sand is dry and fine. Block one end of the pipe with newspapers and fill it with sand. The sand should be compact. Air or moisture in the pipe will make the pipe fold and collapse. When you cannot put in any more send, block the other end, heat it until red hot and bend it manually.

These things can serve your purpose.

How to Take Care of Braided Copper Wire?

Have you got a lot of braided copper wires at home or in your office? Are you planning to buy braided copper wires in bulk? Do you want to learn how to keep them safe enough to use in future as well?

Store the remaining wires in a safe and strong box: In order to keep the wires protected and detangled, it is essential for you to buy a huge box that is strong enough for the wires or cables. Place all the wires together, but make sure that they are not tangled together, or else even if a single copper wire breaks from the braided wire, there are lesser chances for the entire thing to work. Therefore, you need to be extremely careful when you take care of those things, which are used in and for electrical purposes.

Do not entangle the wire in any way at all: No matter how your friends or relatives keep the braided copper wire, you better not allow the wires to be entangled or else they would be of no use in future. To get the best out of such wires, it is necessary for you to place them in a nice box. Keep this box safe and in a secured place. Make sure this box is out of reach of little kids.

Do not clean the wires with water: There are some people, who buy braided copper wires in bulk, thinking that they can clean them with water. Before you do anything like that, it is better to know that NO ELECTRICAL appliance or ANY WIRE that is used for electrical purposes can be washed with water. It is okay to clean the braided copper wire with the help of a wet cloth; this should also be done ONLY if needed!

Top 6 Reason that Makes Copper Wire Best Choice for Building Projects
