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.
Scope of XLPE cable Type No. of Core Nominal cross-section
Cross-section area of neutral conductor
In 3+1cores and 3+2cores should conform to specification of following table：
|Nominal cross-section||Main core||2.5||4||6||10||16||25||35||50|
|Nominal cross-section||Main core||70||95||120||150||185||240||300||400|
D.C Resistance of finished cable at 20℃ per km is not more than the following:
|Nominal cross-section mm2||15||2.5||4||6||10||16||25|
|Nominal cross-section mm2||35||50||70||95||120||150||185|
|Nominal cross-section mm2||240||300||400||500||630||800||1000|
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 90℃
Short circuit: max. for 5 sec.250℃
The cable can be laid without drop restriction, and the environment temperature shall not be lower than 0℃.
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.
