Copper Bare Wires Manufacturer, Bare Copper Wire Price, Exporter & Suppliers in India.
Bare Copper Wire Manufacturer in India, Copper Bare Wire, Copper Wire Suppliers
Amardeep Steel Centre is biggest Bare Copper Wire Manufacturer, Supplier, Exporter in India. Bare Copper Wire is made by bunching/ stranding of multiple numbers of copper wires together in different specification as per client’s requirement. It is designed for extra strength and flexibility. Copper is a good conductor of electricity and generally copper bare wires are used for electric fitting and cable wires are made of copper only. They are also known as “Electrolyte Copper” they are used in subways, conduit, and transit systems both light and heavy. Copper bare wires have great advantages over other wires and are therefore used heavily in all types of electrical fittings all across the world.
Some of these properties of Copper Bare Wire make it best for electrical and other uses
Features Of Copper Bare Wire
Heat Resistant:
copper wires are heat resistant and second in electric conductivity the first being silver. They can also handle a wide load of electricity and it is much easier to handle them. That is why large circuits and subways are made out of copper wires.
Malleability:
This is an important quality of copper wires as their malleability allows them to be shaped in any form easily. The wires take any form that is required
Ductility:
this is another quality of copper wire which makes it even thinner than a strand of human hair that is why bare copper wires are preferred when it comes to headphones and other things in which thin wires are required.
Resistant to corrosion:
Bare copper wires are resistant to corrosion which makes their use even more preferable as in long term they would be easy to handle and use.
Energy Efficient:
Bare copper wires are energy efficient which clearly means that they are heavily used in the manufacturing process as they give better results as compared to other wires. Maintenance of Copper bare wires is also easy and they are easy to handle. So when thinking of wires one should go for copper wires and cables and Amardeep Steel Center is the place where one would get all types of copper wires of good quality.
Application Of Bare Copper Wire
Solid and stranded (classes AA and A) bare copper wire are suitable for overhead transmission and distribution applications. A stranded conductor of greater flexibility (classes B and C) are suitable for uninsulated hook up, jumpers, and grounds in electrical construction. Soft Drawn copper is unilay construction.
Specification of bare copper wire and cable meets or exceeds the following ASTM specifications :
- B-1 Hard-Drawn Copper Wire.
- B-2 Medium-Hard Copper Wire.
- B-3 Soft or Annealed Copper Wire.
- B-8 Concentric-Lay-Stranded Hard, Medium-Hard or Soft Copper Conductor.
- B-33 Tinned Conductors
- B-787 19 Wire Combination Unilay-Stranded Soft copper wire.
