3 core XLPE power cable Application Standards

IEC60502-2009 Power cables with extruded insulationand their accessories for rated voltages from 1kv(Um=1.2kv) up to 30kn(Um=36kv)

 

3 core XLPE power 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.

Tips:

Our Chinese nominal way to name the cable:

YJV stands for Cu conductor XLPE insulated PVC 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

 

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.
