Product Description

1.Application
XLPE insulated power cable has a number of advantages over paper insulated and PVC insulated cable. XLPE cable has high electric 
strength, mechanical strength, high-ageing resisting, environmental stress resisting aiti-chemical, corrosion, and simple construction, using
 convenient and higher operating of long term temperature. It can be laid with no drop restriction.
Various of flame-retardant XLPE cable can be manufactured with three technology .The flame-retardant cable covers all kinds of low-smoke, 
halogen 
free, and non-smoke non-halogenated and three classes of A,B,C.

Voltage test:
Each drum of finished cable should withstand power frequency voltage 3.5kV for 5 minutes,the insulation is not breakdown.
Service conditions and operation parameters of Cable:
The cable is applied to fixed installation for rated voltage 0.6/1kV of power transportation and distribution line.
Max. rated temperature of conductor. nominal operating 90ºC
Short circuit: max. for 5 sec.250ºC
The cable can be laid without drop restriction, and the environment temperature shall not be lower than 0ºC. 
4.Standard
Our XLPE cable can be manufactured according to the company’s specification which is equivalent to IEC 60502,IEC60332,IEC60754. 
Some indexes are superior to above international standard.
