XLPE insulated power cable has anumber of advantages overpaper insulated and PVC insulated cable.XLPE cable has excellent electric property, mechanical property, high ageing resisting, environmetal stress resisting anti-chemical corrossion, and it is simple construction, using convenient and higher operating of long term temperature.It can be laidwith no drop restriction.Various offlame-retardant andnon-flame retardant XLPE cable can be manufacturedwith 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 ofA, B, C.
Our XLPE cable can be manufactured according to company's specification which is equivalent to IEC60502,IEC 60 332, and IEC 60 754. 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 reducedsize (nominal cross-section) 1 or 2 class in comparison with paper and PVC cable. This is not only improve the quality and properties of products, but also reduce cable's production costs.
