Mar. 13, 2018

Y- (polyethylene power cable), J- (crosslinking), V- (PVC sheathed), YJV cable fully called crosslinked polyethylene insulated PVC sheathed power cables. Most of the black outer cables we see are YJV cables.

Usage conditions and precautions of YJV cable:


Different YJV cables have different usage characteristics, and the frequency rated UO/U is 0.6/1kv.

the long-term maximum operating temperature of cable conductor is 90 ℃.

When a short circuit (the longest duration no more than 5 s) cable conductor does not exceed the highest temperature of 250 ℃.Cable laying ambient temperature should not be less than 0 ℃.Single-core cable bending radius: not less than 15 times the cable diameter, multi-core cable is not less than 10 times the cable diameter.


Special tools should be used for cable laying, such as line frame, guide roller, etc., to prevent mechanical damage during laying and keep away from heat source.When the cable is laid out, the inner diameter of the pipe shall not be less than 1.5 times of the outer diameter, and the cable shall not be compressed when the cable is in pipe, and the total area of the cable shall not exceed 40% of the total area of the pipe.
