IEC60502-2009 Power cables with extruded insulationand their accessories for rated voltages from 1kv(Um=1.2kv) up to 30kn(Um=36kv)
XLPE Cable Applications
- Rated voltage from Uo/U(Um)3.6/6(7.2)KV to26/35(40.5)KV
-Armored cable is suitable for burying in ground.Able to bear external mechanical force but not large pulling force
-None armored cable suitable for layingindoors and outdoors. Able to bear a certain traction during installation, butnot external mechanical forces. Laying single core cable in magnetic ducts isnot allowed.
-Steel tape armoured and steel wire armoured and aluminum wire armoured.

XLPE Cable Model Code Explaination:
Our Chinese nominal way to name the cable:
YJV stands for Cu conductor XLPE insulatedPVC sheathed Power Cable
YJLV stands for Al conductor XLPE insulatedPVC sheathed Power Cable
The subscript 22 is stands for Steel Tapearmored Power Cable
Then subscript 33 is stands for Steel Wirearmored Power Cable
XLPE Cable Installation
-The long time operating temperature shallnot exceed 90°C, Conductorshort circuit temperature for 5 seconds shall not exceed 250°C.
-Installation temperature requires above 0°C,
-The bending radius shall not less than 10time of the cable’s O.D.
