Rail transit cable

Specifications

This kind of products is applied to the urban rail transit, and it can be also used in DC 750V traction power transmission or DC 

Parameter scope:

1.The long-term continuous conductor temperature not exceeding 90 °C;

2.The maximum temperature of conductor does not exceed 250 °C when the cable short circuit within 5 seconds;

3.Minimum bend radius of installing cables should be consistent with the standard ,it  is GB/T12706.1. The cable must be installed under the ambient temperature more than 0 °C.

Generally, the products are water-resistant, oil-resistant, anti-sunburn, anti-mouse and anti-termite. Power transmission is high efficient and low loss. The products are applied to 750V/1500V/2temperatureV DC distribution system for urban rail transit.

When short circuit occurs, bending radius is 12 times as long as outer diameter. Halogen-free, low-smoke and flame retardant cables never get burned and never cause emission of heavy smoke and poisonous gas to prevent second hazard. Water-proof and oil-resistant cables are suitable for harsh condition.
