Properties ,
Combustion performance (flame retardant cable) according to GB/T18380-2001 standard test
Operating characteristic ,
1. Cable highest long-term working temperature is 90 C
2. Cable the ambient temperature under installation should not below 0 C, cable bending radius should be more than twenty times of cable diameter
3. In case of short circuit, the highest temperature of the conductor shall not be more than 250 C, duration is no more than 5 seconds
4. Laying temperature shall not be lower than 0 C
5. Short circuit, the highest temperature of the conductor shall not be more than 160 C, duration is no more than 5 seconds
6.used for rated voltage 1.8/3 0.6/1, 3.6/6, 6/6, 6/10, 8.7/10, 8.7/15, 12/20, 21/35, 26/35 kv, power transmission and distribution system.
7. YJV YJLV suitable for indoor and outdoor installation, can withstand certain laying traction, but unable to bear external mechanical forces of situations. Single core cable are not allowed in the pipe laying in ferromagnetic materials. YJV22, YJLV22 suitable for buried laying, able to bear external mechanical forces effect, but unable to bear large pulling force.
