Today, BAIJIAN will introduce to you the relevant content of railway locomotive and vehicle cable testing services
Usage characteristics of railway locomotive wires and cables
1. Rated voltage (AC) is divided into 500V, 750V, 1500, 3000.
2. The allowable long-term working environment for the cable core is 125 ℃, and the temperature during short circuit should not exceed 250 ℃ (short circuit time is 5S).
3. Minimum ambient temperature for cable use: -40 ℃ for non high-strength thin-walled railway passenger cars, -60 ℃ for non high-strength thin-walled railway passenger cars 4. Non high-strength thin-walled railway passenger car cables are allowed to be used in environments with various types of grease pollution, while high-strength thin-walled railway passenger car cables are allowed to be used in harsh environments with various types of grease pollution and non high concentration of acid and alkali pollution5. Allowable bending radius for cable laying:
When the cable diameter is less than or equal to 10mm, it should not be greater than twice the outer diameter of the cable When the cable diameter is greater than 10mm, it is less than or equal to 20mm and not more than 4 times the outer diameter of the cable
