Copper Cables

Share |

Copper is one of the most widely used metals in the field of electrical fittings and specially in making cables and wires. Due to its excellent electrical properties like electrical conductivity, and magnificent physical properties like light weight, malleability, and ductility copper has become the premiere element for manufacturing top quality cables. Almost in each type of cables whether it is copper control cables, copper power cables, copper telephone cables or any other cables, copper cable is the best suited to these functions.

Types of Copper Cables
Copper is used to make different types of cable which are used in several industries.

Control Copper Cables
Power Copper Cables
Telecommunication Copper Cables
Offshore/Marine Copper Cables

Applications of Copper Cables in Different industries

Telecommunication industry
Electrical power industry
Electrical machineries
Mining industry
Transportation industry

Why Copper is Perfect for Making Electrical Cables?

High electrical conductivity: Due to its high electrical conductivity, the flow of electricity in copper is very fine so it is perfect for making electrical cables.

High ductility: Due to high ductility copper can be stretched into thin fine wires. It can be stretched into any length and of varying sizes.

Good strength: The strength of copper is suitable for making different types of cables.

High resistance to corrosion: Due to its high resistance to corrosion, copper is suitable for making electrical wires and cables. This property makes it suitable for under water uses.

High resistance to creeping: Due to its excellent mechanical strength, copper cables are resistant to creeping and can withstand sufficient load and pressure.

Alloys of Copper

Copper alloys also play an important part in manufacturing electrical cables and wires. Bronze, brass, and copper-tin alloy are some of the most valuable alloys of copper.

Bronze: It is 60% copper and 40% tin. Some other elements are also mixed in it to attain certain specific properties. Bronze is very good for making electrical fittings.

Brass: It is an alloy of copper and zinc. Its electrical and physical characteristics almost resemble to copper hence used in making different types of electrical fittings.

Consumption of Copper Around The World
Among the total production of copper in the whole world the maximum amount is used in making electrical equipment and specially in cables and wires. Here is given a rough idea about its consumption in different areas.

60% of the copper is used for making electrical equipment.
20% of the copper is used in construction purposes like roofing and plumbing.
15% of the copper is used in manufacturing industrial machinery like heat exchangers.
5% of the copper is used in making alloys like bronze and brass.
