U1000 Rvfv Cable 3X50sqmm Copper Conductor XLPE Insulated
(Low voltage and medium voltage)
1.Brief of XLPE insulated Power Cable
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-aging resistance,environmental stress resisting anti-chemical corrosion,and it is simple construction,using convenient and higher operating of long term temperature.It can be laid with no drop restriction.
Various of flame-retardant and non-flame retardant XLPE cable can be manufactured with three technology(peroxide,silence,and irradiation,cross linking).The flame-retardant cable covers all kinds of low-smoke,low-halogen,low-smoke halogen free and non-smoke no halogenated and three classes of A,B,C.
Our XLPE cable can be manufactured according to company’s specification which is equivalent to IEC60502,IEC60332,IEC60754.Some of indexes are superior to above international standard IEC.
Some special XLPE cable can be manufactured according to the other standards required by customers.
XLPE cable having higher long-term working temperature and greater current rating,at the same environment XLPE cable may be reduced size(nominal cross section)1 or 2 class in comparison with paper and PVC cable.These are not only improving the quality and properties of products,but also reduce cable’s production costs.
2.Scope of XLPE Cable
|Type||Number of Core||Nominal Cross section of conductor mm2|
ZR covers three classes A,B,C of flame-retardant cable.It can be expressed as ZRA or ZRB or ZRC separately.For example:ZRB-YJV or ZRA-YJV22
Only technical data of common cable are listed in Table of Cable’s construction,weight and electrical properties.
Attached Table:Cross section area of neutral conductor in 3+1cores,4+1cores,and 3+2cores should conform to specification of following table:
|Nominal Cross section mm2||Main cores||2.5||4||6||10||16||25||35||50|
|Nominal Cross section mm2||Main cores||70||95||120||150||185||240||300||400|
