Detailed Product Description
1. 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-ageing resisting, 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, silance and irradiation crosslinking). The flame-retardant cable covers all kinds of low-smoke low-halogen low-smoke halogen free, and non-smoke non-halogenated and three classes of A,B,C.
Our XLPE cable can be manufactured according to company specification which is equivalent to IEC 60502, IEC 60332,and IEC 60754.Some of indexes are superior to above international standard IEC.
Some of special XLPE cable can be manufactured according to the 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)1or 2 class in comparison with paper and PVC cable. This is not only improve the quality and properties of products, but also reduce cables production costs.
