交聯(lián)聚乙烯絕緣電力電纜XLPE INSULATED POWER CABLE一、交聯(lián)聚乙爆絕緣電力電纜簡介 Brief introlluction to Xlpe lnsulated Power Cable我國自從六十年代以來，交聯(lián)染乙烤電纜得到飛速發(fā)展，已經(jīng)取代了油浸紙絕緣電力電境，交聯(lián)電黣，因其具有優(yōu)異的電氣性能、良好的熱過載特性，電壓等級高，傳輸容量大、重量輕及數(shù)設(shè)不受落差、可垂直數(shù)設(shè)，電纜安裝和運(yùn)行維護(hù)方便等優(yōu)點(diǎn)，它不僅可以在35KV及以下的中，低壓范圍內(nèi)得到廣泛應(yīng)用，而且在66.110及220KV的高壓輸電線路中也已大量采用，并且在某些先進(jìn)工業(yè)國家已經(jīng)開發(fā)出了500KV壓交聯(lián)電力電纜。Since the 1960s,China has made rapid progress in its XLP'E cable,replacing the oil paper insulated power cable, Because of its outstanding electricityproperty.good overload,high voltage,.large transmission capacity.light weight and laying without drop limit,vertical laying.convenient installation andoperation maintenance and other strong points,XL. cable can not only be widely used in 35KV and below medium and low voltage scope, but also largelyused in 66,110 and 220KV high voltage transmission lines. And, in some developed industrial countries 500KV super-high voltage XL, cables have beenopened up.二、產(chǎn)品標(biāo)準(zhǔn) Product Standard:我廠按國際GB/T12706-2008《額定電壓1KV到35KV擠包絕緣電力電境及附件），GB11017-89《額定電壓110KV銅芯，鋁芯交聯(lián)聚乙烯絕緣電力電纜）生產(chǎn)交聯(lián)雜乙烤電埋，GB/T12706-2008標(biāo)準(zhǔn)等效國際標(biāo)準(zhǔn)IEC502-2001《額定電壓1-30KV的擠包絕緣電力電境及附件），GB11017-89參照采用國際標(biāo)準(zhǔn)IEC810-1988（額定電壓：30KV-150KV擠包絕緣電力電纜實(shí)驗(yàn)）。本廠還可以根據(jù)用戶要求，設(shè)計(jì)制造具有某些特殊要求的交聯(lián)電纜Our factory produces XLPE cable according to state standard GB/T12706-2008 "Rated voltage 35KV and below copper core and aluminium coreplastic insulated power cable" and GB11017-89 "Rated voltage 110KV copper core and aluminium core XLPE insulated power cable" .The GB/T12706-2008 standard is equivalent to international standard IEC502-2004 "Rated voltage 1-30KV plastic extruded and wrapped insulated power cable.TheGB11017-89 standard adopts intermational standand IEC840-1988 "Rated voltage 30-150K extruded and wrapped insulated power cable experíment" .Our fatory can also design and produce some XL. cable for special requirements according to clients' demand.三、使用性能 Property for Use:1電纜導(dǎo)體的高額定溫度為90℃。2短路時(shí)（長持續(xù)時(shí)間不超過5S)電纜導(dǎo)體的高溫度不超過250℃.1.
