Copper Clad Steel Wire

CCS Copper Clad Steel stranded wire is a special type of electrical wire that combines the conductivity of copper with the strength and durability of steel. It consists of multiple small gauge wires twisted together, enhancing flexibility and durability compared to single solid wires. Despite steel's lower conductivity, the copper coating ensures good conductivity while the steel core provides mechanical strength. The steel core grants the wire higher tensile strength, making it more resistant to stretching and breaking. Additionally, CCS wire is lighter than pure copper wire, which proves advantageous in certain applications.

Application

● Telecommunications: Used in cables for telephone lines and other communication systems due to its strength and adequate conductivity.

● Antenna Systems: Ideal for radio antennas and transmission lines because of its strength and resistance to stretching.

● Power Transmission: Sometimes used in overhead power lines and grounding systems where mechanical strength is critical.

● Railway Electrification: Utilized in railway electrification systems where high strength and durability are required.

Construction

The construction of soft-annealed copper-clad steel (CCS) conductors involves a concentric-lay stranded design. These CCS strands incorporate a low-carbon steel core with a 40% conductivity grade material, providing improved flexibility for easier handling during installation. The outer copper layer ensures good electrical conductivity while the steel core offers mechanical strength and durability.
