Electrified railway catenary is in along the rail over "the" shape erection

Electrified railway catenary is in along the rail over "the" shape erected for pantograph high voltage transmission lines to take the stream. Catenary railway electrification project of the main frame is erected along the railway line air supply to the electric locomotive special form of transmission lines. The suspension from the contact support means, the positioning means, post and base of several parts. air circuit breaker contains the following elements: 1. Basic components, such as cement pillars supporting steel Voltage stabilizer and the foundation of these structures; 2 base mounting structure, the role of this element is mainly connected catenary Electric energy meter member; 3 catenary wire, this part of the role is to transmit current to the electric locomotive; 4 other auxiliary components, including the return line, the additional suspension and so on. Catenary, rail and earth return wire referred to as traction network.
