Copper stranded wire is a kind of conductor made of multiple copper wires twisted together. Common materials include red copper and tinned copper.

Copper stranded wire inherits the good conductivity of copper and can be used to transmit electricity. Overhead transmission lines will use copper stranded wire to transmit electricity and reduce the loss of electricity during transmission. Moreover, copper stranded wire is more flexible. Compared with solid copper wire, it is easier to bend and erect during construction, which is convenient for installers to operate. This has obvious advantages in complex line laying environments.

In terms of tensile strength, the structure of multiple copper wires twisted together gives it good tensile strength. For example, in some power connection scenarios that need to withstand a certain amount of tension, such as the transmission line across rivers, copper stranded wire can effectively avoid breakage due to excessive tension.

Advantages of copper stranded wire in power transmission

- Overhead transmission lines: used for long-distance power transmission, copper stranded wire has good conductivity and low loss, and can effectively transmit power from power stations to substations. And its good flexibility and tensile strength enable it to adapt to different geographical environments and meteorological conditions, such as transmission lines across complex terrains such as valleys and rivers.

- Indoor power wiring: In some places with high requirements for power transmission quality, such as large data centers, hospital operating rooms, etc., copper stranded wire can be used as wires for connection between equipment and distribution boxes to ensure stable power supply.

Copper stranded wire can also be used in the field of communications

- Communication cables: Copper stranded wire can be used as the core wire of communication cables to transmit telephone signals, network data, etc. Its good conductivity helps to transmit signals over long distances, and it can resist a certain degree of electromagnetic interference to ensure the quality of communication.

Copper stranded wire is also widely used in rail transportation

- Electrified railway contact network: As a contact line, it transmits electric energy from the traction substation to the pantograph of the electric locomotive. The high conductivity and flexibility of copper stranded wire can meet the power supply requirements when the train is running at high speed, and can withstand the vibration and tension of the contact network when the train is running.

Copper stranded wire is indispensable for industrial applications

- Motor winding: In motor manufacturing, copper stranded wire can be used to make motor windings. Its good conductivity can reduce the energy loss of the motor during operation, improve the efficiency of the motor, and can withstand the heat and mechanical stress generated when the motor is running.
