0.6/1kv 600/1000V Underground Power Cable PVC/XLPE Insulated Swa 3 Cores
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,
free, and non-smoke non-halogenated and three classes of A,B,C.
Scope of XLPE cable
Type No. of Core Nominal cross-section
|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 20ºC 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 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.
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.
