Catenary wire is also known as tram lines, catenary is an important part of the world. Electric locomotive running its pantograph direct contact friction, and from the contact line to get electricity. air circuit breaker, contact wire cross-sectional area should be chosen to meet the requirements of traction power calculation.
Generally made on both sides of the line of contact with the cylindrical groove, which groove clamps for ease of installation and press the technical requirements of suspension fixed contact line position electric meter the pantograph taxi to take stream. Below the line of contact with the pantograph contact arcuate portion, called the line of contact face. Chinese copper contact wire used mostly for two models, the letter T copper, C represents the tram line, G represents grooved form, the latter figure indicates that the copper contact wire cross-sectional area. In recent years, China also introduced a copper contact wire used in Japan.
