Q: What is the special cable for rail transit?

A: Thin-wall insulated cable for rail transit vehicles is a cable used for electrical control equipment in locomotive. It adopts tin-plated soft copper conductor and halogen-free low-smoke flame-retardant insulation material, and is produced by thin-wall manufacturing technology. It has the characteristics of small volume, light weight, heat resistance, oil resistance, acid and alkali resistance, cold resistance, wear resistance and ozone resistance. Especially suitable for high-speed and ultra-high-speed rolling stock relatively closed, personnel concentration and other environmental requirements of the rolling stock internal distribution cabinet and power supply system.

Q: What are the characteristics of the cable?

The cable is made of tin-plated soft copper conductor and halogen-free low-smoke flame-retardant insulating material, and is produced by thin-wall manufacturing technology. The product is small in size and light in weight, and has the characteristics of heat resistance, oil resistance, acid and alkali resistance, cold resistance, wear resistance and ozone resistance. It has excellent physical and mechanical properties, convenient installation, safe use and reliable operation. In the case of fire, it can effectively limit the spread of fire and the release of smoke to avoid danger to personnel.
