describe catenary wiring system

A catenary wiring system is a type of overhead electrical wiring system that is used to supply power to trains or other vehicles. In this system, the electrical cables are suspended from a series of poles or towers, forming a “catenary” shape. The weight of the cables is supported by the poles or towers, and the electrical current is transmitted through the cables to the vehicles.

Two suitable cables that are commonly used in a catenary wiring system are:

1. Copper conductor cables: Copper conductor cables are made of copper wire and are used to transmit electrical current in the catenary wiring system. Copper is a good conductor of electricity and is resistant to corrosion, which makes it an ideal choice for use in overhead electrical wiring systems.
2. Aluminum conductor cables: Aluminum conductor cables are made of aluminum wire and are also used in catenary wiring systems. Aluminum is a good conductor of electricity and is lightweight, which makes it easier to install and maintain in overhead wiring systems. However, aluminum is more prone to corrosion than copper and may require more maintenance to prevent degradation.
