Product Introduction

Scope of application:

This product is applied to the cables for electric devices of distribution system, control system and signal system for wires and cables for railway passenger cars with rated voltage below 3KV. It is especially suitable for narrow space and occasions with special requirements such as low smoke, halogen-free and flame retardant

roduct executive standard: GB / T 12528-2008 TB / t1484-2017 JB / t8145-1995

Usage characteristics:

Rated voltage (AC) is divided into 500V, 750V, 1500V and 3000V

The allowable long-term working environment of cable core is 125 ℃, and the temperature during short circuit shall not exceed 250 ℃ (short circuit time is 5S)

Minimum operating ambient temperature of cable: cable for non high-strength thin-walled railway passenger car is - 40 ℃,- 60 ℃ for non high strength thin wall railway passenger car cable

Cables for non high-strength thin-walled railway passenger cars are allowed to be used in various grease polluted environments, and cables for high-strength thin-walled railway passenger cars are allowed to be used in harsh environments with various grease pollution and non high concentration acid-base pollution

Allowable bending radius of cable laying:

When the cable diameter is less than or equal to 10mm, it shall not be greater than 2 times of the outer diameter of the cable;
When the cable diameter is greater than 10mm, it is less than or equal to 20mm and not greater than 4 times of the outer diameter of the cable;

When the cable diameter is greater than 20mm, it shall not be greater than 6 times of the outer diameter of the cable
