The contact network is set up in the electrified railway and "Zhi" shaped along the steel rails, which is set up for high -voltage transmission cables with electric bows.The contact network is the main structure of the railway electrification project. It is a special form of power transmission line to power the electric locomotive along the railway.
Overhead cable specification
The model specifications, names and scope of overhead cables are: 1. JKVJKLVJKYJKLYJKYJJKLYJ copper, aluminum core polyvinyl chloride insulator overhead cable copper copper, aluminum core polyethylene insulation cable copper copper, aluminum core junviene insulation cable, for overhead fixationSet the attracting line.
Overhead cable line
The overhead cable route is composed of wires, horizontal burden, foundation, pole tower, gold gear, and pull wires.The overhead cable line is very small due to the surrounding environment and pollution. The power delivery is very reliable. The insulation distance between its lines is very small and will not interfere with the radio waves.At the time, it is not easy to expose the target, and it is also very safe and reliable.Of course, there is a good side on the good side. Its disadvantage is that the cost is high, the cost is large, the cable failure is difficult to find and repair, and the cable line is not easy to change and branch.
