Copper Catenary Wire For Electric Railway Good Electrical Conductivity
Copper Catenary Wire for Electric railway good electrical conductivity
Copper catenary is a kind of overhead wire used in transmission and distribution system. It is mainly made of copper, a highly conductive metal known for its excellent electrical and thermal properties. Catenary refers to the shape of a wire when suspended between two supports, forming a curve similar to a parabolic arch.
The copper catenary wire is designed to carry high electrical currents over long distances with minimal energy losses. It is often used in high-voltage power lines that transmit electricity from power plants to substations and distribution networks. The wire is typically supported by towers or poles, and its catenary shape allows it to distribute the mechanical tension evenly along its length.
Application
- For use as overhead power source for subways, light and heavy transit systems, electrically powered mine trains, buses, and industrial cranes.
- Catenary wire can carry a certain current to reduce the impedance of the traction network, reducing voltage loss and energy consumption.
- Catenary wire material can be divided copper catenary wire, steel catenary wire, aluminum clad steel load-bearing cable. Steel catenary need to take anti-corrosion measures.
It's important to note that the manufacturing process of copper catenary wires may be subject to specific industry standards and regulations, as they are critical components of electrified railway systems. The process may also vary based on the specific requirements and design parameters of the railway infrastructure.
