What YJV cable?
YJ ---- Cross-linked polyethylene insulation
V ---- PVC sheath
The name of the YJV cable model is: XLPE insulated and PVC sheathed power cable
XLPE insulated power cables have excellent thermo-mechanical properties. Excellent electrical properties and chemical resistance. It also has the advantages of simple structure, light weight, and no drop limit for laying. It is a novel cable widely used in urban power grids, mines and factories.
Cable insulation-cross-linked polyethylene: It is a cross-linked polyethylene that uses chemical and physical methods to convert linear molecular structure polyethylene into a three-dimensional network structure. Thereby greatly improving the thermomechanical properties of polyethylene, thereby maintaining excellent electrical properties.
The maximum rated working temperature of XLPE insulated power cable conductor is 90℃. The working temperature is higher than that of PVC insulated and polyethylene insulated cables, so the current carrying capacity of the cable is further improved.
