　　產(chǎn)品簡(jiǎn)介Introduction

　　該產(chǎn)品是在緊壓的銅、鋁導(dǎo)體擠制內(nèi)屏蔽層和耐候交聯(lián)聚乙稀或耐候型黑色高密度聚乙稀絕緣層和外屏蔽層而制得(1kV架空絕緣電纜沒(méi)有內(nèi)外 屏蔽層)，結(jié)構(gòu)簡(jiǎn)單、安全可靠，同時(shí)又具有優(yōu)良的機(jī)械物理性能和電氣性能，耐電痕、耐沿面放電、耐大氣性能優(yōu)良，與祼電線相比，敷設(shè) 間隙小，節(jié)約線路走廊，線路電壓降減小，尤其是減少供電事故發(fā)生，確保人生安全。

　　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.
