Introduction:

The DC traction cable of rail transit is the network cable and return cable connecting the high-speed DC switch and catenary in the DC traction power supply system of urban metro, ground light rail and other rail transit. The insulation structure of the cable is designed according to the characteristics of the DC power supply system. The cross-linked polyethylene or ethylene propylene rubber with excellent electrical performance is used as the insulation material to ensure that the cable has excellent electrical insulation performance. At the same time, the cable also has excellent water-proof performance, high flame-retardant, halogen-free, low smoke environmental protection performance as well as anti UV, anti rat and anti termite performance, which can meet the requirements of complex application environment of rail transit cable, high requirements of safety and environmental protection performance, and ensure the long-term safe and reliable operation of the cable. In addition, the DC traction cable of rail transit may be used in the underground tunnel, and the laying environment is relatively narrow. The cable also has certain bending resistance, which can meet the needs of smaller bending radius during the use of the cable.

Purpose:

The DC traction cable for rail transit is applicable to the DC 1500V and below low-voltage positive cable, connecting cable and negative cable that directly supply power to the traction locomotive in the urban subway and light rail power supply system.

Characteristic:

1. The cable has excellent electrical insulation performance and stable and reliable transmission. 2. The cable has excellent environmental protection performance of high flame retardant, halogen-free and low smoke. 3. The cable has excellent safety performance against ultraviolet, water, rat and termite.
