Power cable jkv

JKV/B cable belongs to overhead insulated cable. The Chinese name of JKV/B cable is copper-core PVC insulated separable combined overhead insulated cable. The service voltage of JKV/B cable is 0.6/1KV, and the common specification of JKV/B cable is 1 * 10; 1*16; 1*25; 1*35; 1*50; 1*70; 1*95; 1*120; 1*150; 1*185; 1*240。

Yjy-jkv wire and cable

YJV-JKV is only applicable to 1kV copper core XLPE insulated PVC sheathed overhead cable.    1. The name of YJV cable model is cross-linked polyethylene insulated PVC sheathed power cable.    2. JKV is a copper core PVC insulated overhead cable, which is only applicable to 1kV.    

Jkv function of power cable.    

Cross-linked polyethylene insulated power cable has excellent thermo-mechanical performance, excellent electrical performance and chemical corrosion resistance, and also has the advantages of simple structure, light weight, and laying free of drop restrictions.

Purpose of power cable

At present, it is widely used in urban power grids, mines and factories. JKV overhead cable is used for overhead fixed laying or household incoming line, and is only used in 0.6/1KV lines. Insulation-crosslinked polyethylene (XLPE) of cables uses chemical and physical methods to convert linear molecular structure of polyethylene into three-dimensional network structure of cross-linked polyethylene, thus greatly improving the thermal mechanical properties of polyethylene and maintaining excellent electrical properties. The maximum rated working temperature of XLPE insulated power cable conductor is 90 ℃, higher than that of PVC insulated and PE insulated cables, so the current carrying capacity of the cable is also further improved.
