YJV series


YJ----Crosslinked polyethylene insulation

V----PVC sheath

YJV The name of the cable type is: XLPE insulated PVC sheathed power cable.

XLPE insulated power cable has excellent thermal mechanical properties, excellent electrical and chemical corrosion resistance. It has the advantages of simple structure, light weight, and not limited to falling drop. It is a new cable widely used in urban power grid, mine and factory.

The insulated crosslinked polyethylene (PE) of the cable is a cross-linked polyethylene that uses chemical methods and physical methods to convert polyethylene of linear molecular structure into a three-dimensional reticulated polyethylene, which greatly improves the thermal mechanical properties of polyethylene and thus maintains excellent electrical properties.
 The maximum rated working temperature of the conductor of XLPE insulated power cable is 90 C, which is higher than PVC insulation and polyethylene insulated cable, so the capacity of cable is further improved.

Detailed parameters



Copper core


Aluminum core


Scope of application





Copper core or aluminum conductor XLPE insulated PVC sheathed power cable

In the room, in the tunnel, in the cable trench and in the pipe, it can also be buried in the loose soil. The cable can bear certain traction, but can not bear the mechanical force.





Copper core or aluminum core XLPE insulated steel tape armored PVC sheathed power cable

It is suitable for indoor, tunnel, cable trench and underground direct buried installation. Cable can bear mechanical external force, but it can not bear large pulling force.

Scope of application

This product is suitable for fixed laying in distribution network or industrial device with rated voltage 0.6/1KV or below. It is often used for aerial work.
