一、電纜不一樣
1、電力電纜
電(dian)(dian)力(li)電(dian)(dian)纜是用以傳送和分派電(dian)(dian)磁能的電(dian)(dian)纜線,電(dian)(dian)力(li)電(dian)(dian)纜常見于大城(cheng)市地底(di)電(dian)(dian)力(li)網、發(fa)電(dian)(dian)廠引出來路線、廠礦(kuang)企(qi)業(ye)內部供電(dian)(dian)系統及過新海水中電(dian)(dian)力(li)線。
2、架空電纜
架空(kong)電(dian)(dian)纜(全名空(kong)架絕緣電(dian)(dian)線(xian)),是(shi)配有電(dian)(dian)纜護套和維護表皮的空(kong)架輸(shu)(shu)電(dian)(dian)線(xian),選(xuan)用類似交聯電(dian)(dian)纜生產工(gong)藝流程生產制造的一種專用型(xing)電(dian)(dian)纜線(xian),是(shi)接近空(kong)架輸(shu)(shu)電(dian)(dian)線(xian)和地(di)底電(dian)(dian)纜線(xian)中間(jian)的新的輸(shu)(shu)配電(dian)(dian)方法。
二、歸類(lei)不一(yi)樣
1、電力電纜
按(an)額(e)定電壓(ya)(ya)可分(fen)成(cheng)(cheng)中、低壓(ya)(ya)電線電纜(35KV及(ji)下列)、高壓(ya)(ya)電纜線(110KV之上)、超(chao)高壓(ya)(ya)電纜(275~800KV)及(ji)其特高壓(ya)(ya)電纜線(1000KV及(ji)之上)。除此之外,還可按(an)電流(liu)(liu)量制分(fen)成(cheng)(cheng)溝通交流(liu)(liu)電纜線和直流(liu)(liu)電電纜線。
2、架空電纜
一般的架空電纜全是單芯的,按其構造(zao)(zao)不一樣可分(fen)成碳(tan)素(su)工具(ju)鋼(gang)線(xian)(xian)(xian)構造(zao)(zao)、拉扯銅(tong)(tong)心線(xian)(xian)(xian)構造(zao)(zao)、鋁合金型材線(xian)(xian)(xian)構造(zao)(zao)、鋼(gang)芯或鋁合金型材芯支撐點(dian)構造(zao)(zao)和自(zi)承式三(san)芯紋合構造(zao)(zao)(線(xian)(xian)(xian)芯能為(wei)碳(tan)素(su)工具(ju)鋼(gang)或硬銅(tong)(tong)心線(xian)(xian)(xian))等。
三、特點(dian)不一樣
1、電力電纜
1)占地(di)面積(ji)少(shao)。一般(ban)鋪設(she)于(yu)土壤層中(zhong)或鋪設(she)于(yu)房間內,斷面,隧道施工中(zhong),電線間絕緣層間距小(xiao),無需(xu)塔桿(gan),占地(di)面積(ji)少(shao),基礎不占地(di)面積(ji)表面室內空間。
2)可信性高。受氣候條件和周邊環境危害小,傳送特性平穩。
2、架空電纜
1)供電系統(tong)可信(xin)性高
選用架空電線(xian)可大幅度降低各種的(de)短路故(gu)障常(chang)見故(gu)障(尤其是空架裸輸電線(xian)普(pu)遍的(de)短路故(gu)障性常(chang)見故(gu)障),與空架裸輸電線(xian)對比(bi),設備故(gu)障率要低4-6倍(bei)。
2)供電(dian)系統安全系數好
選用架空電纜使人(ren)身安全觸電事(shi)故安全事(shi)故大幅降低。
