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-agcing resisting,environmental stress resisting anti-chemical corrossion,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-retandant and non-flame retardant XLPE cable can be manufactured with three technology(peroxide,silance and irradiation crosslinking).The flame-retardant cable covers all kinds of low-smoke low-halogen,low-smoke halogen free,and non-smoke nonhalogenated and three classes of A,B,C. Our XLPE cable can be manufactured according to company's specification which is equivalent to IEC60502,EIC 60332,and IEC 60754.Some of indexes are superior to above international standard IEC. Some of special XLPE cable can be manufactured according to ther other standards required by customs. 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.

*"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+1 cores,4+1 cores and 3+2 cores should conform to specification of following table:
