PRODUCTS CENTER
Use
This product is suitable for circuits of AC 50Hz and rated voltage 0.6/1kv for power transmission and distribution.
Working conditions
1)The maximum rated temperature of the cable conductor is 70 ℃.
2)The maximum temperature of the cable conductor does not exceed 160 ℃ in case of short circuit (the longest duration is no more than 5s).
3)The ambient temperature of the cable is not less than 0 ℃ during laying, and the minimum bending radius should be not less than10 times of the cable outer diameter.
