Electric cable is adopted in transmission and distribution system of electricity.The XLPE cable with alternating-current rated voltage of 0.6/1KV and the cross-link XLPE cable of 35KV and below produced by us not only perform well up to the standards of GB12706,IEC60502 and IEC60840,but also have formed a series,ie.cables of flame-retardant model,refractory model,forts-proof model and water-proof model.
The technique of oxide-blanket insulation has been successfully applied to the flame-retardant series.Not only have XLPE cable of 0.6/1KV and cross-link XLPE flame-retardant cable reached class A of GB/T12666.5 Test on bunched wires or cable,cross-link flame-retardant XLPE cable with rated voltage of 6/10KV and 8.7/15KV has also reached Class A highly flame-retardant qualification with a margin.On the basis of the cross-link flame-retardant XLPE series,we have developed the low-smoke non-halogen highly flame-retardant oxygen-tight electric cable,the low-smoke non-halogen degree of which conforms to the national standard of GB/T17651.1.2 and GB/T17650.1.2.In general, the cross-link flame-retardant XLPE electric cable produced by us has been in the leading position domestically.
The refractory-modle cable produced by our factory is the copper-cored cable with the rated voltage of 0.6/1KV,low-smoke non-halogen refractory cable and highly flame-retardant cable,the flame-retardant performance of which is in conformity to GB/T12666.6 Test on fire resisting characteristics of wire or cable,so ,generally the electric cable of refractory series performs well.
The water-proof cable conforms to the standards of IEC502-2.
