产品简介Introduction
该产品是在紧压的铜、铝导体挤制内屏蔽层和耐候交联聚乙稀或耐候型黑色高密度聚乙稀绝缘层和外屏蔽层而制得（1kV架空绝缘电缆没有内外 屏蔽层），结构简单、安全可靠，同时又具有优良的机械物理性能和电气性能，耐电痕、耐沿面放电、耐大气性能优良，与祼电线相比，敷设 间隙小，节约线路走廊，线路电压降减小，尤其是减少供电事故发生，确保人生安全。
The products are manufactured by extruding a conductor screen layer, an insulated layer of rough-weather-adaptive XLPE or rough-weather-adaptive black HD-PE or PVC, and an insulation screen layer over the compacted copper/aluminium conductor(no conductor screen layer and insulation screen layer for cables of rated voltage 1kV),with the advantage of simple construction, and excellent mechanical,physical and electrical property as well as fine performance of anti-creeping- discharge, rough-weather-adaptive and creepage-proof. Compared with bare conductor, the product can be laid more closely to save the line gallery, and have less voltage-drop. Above all, the products installed reduce power accidents to insure lives safety.
