伴隨著(zhu)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)在(zai)配網(wang)(wang)(wang)(wang)中的持續營銷推廣與應用，配網(wang)(wang)(wang)(wang)可分成電(dian)(dian)(dian)纜(lan)(lan)線(xian)互(hu)(hu)聯網(wang)(wang)(wang)(wang)和空(kong)架互(hu)(hu)聯網(wang)(wang)(wang)(wang)（含空(kong)架、電(dian)(dian)(dian)纜(lan)(lan)線(xian)混(hun)和互(hu)(hu)聯網(wang)(wang)(wang)(wang)）。《關于〈城市(shi)中低壓配電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)改(gai)造技術導則〉的實施情(qing)況及補充(chong)意見》也對(dui)電(dian)(dian)(dian)纜(lan)(lan)線(xian)配電(dian)(dian)(dian)設(she)(she)備(bei)互(hu)(hu)聯網(wang)(wang)(wang)(wang)自動化(hua)(hua)技術明(ming)確提出(chu)了實際規定(ding)。因(yin)而(er)，在(zai)配網(wang)(wang)(wang)(wang)地區互(hu)(hu)聯網(wang)(wang)(wang)(wang)選用電(dian)(dian)(dian)纜(lan)(lan)線(xian)互(hu)(hu)聯網(wang)(wang)(wang)(wang)時(shi)，應依照配電(dian)(dian)(dian)自動化(hua)(hua)的規定(ding)，選用新技術應用、新機器設(she)(she)備(bei)，有標(biao)準的要考(kao)慮到自動化(hua)(hua)技術試點，標(biao)準不成熟的還要在(zai)配套設(she)(she)施機器設(she)(she)備(bei)型號選擇(ze)時(shi)，考(kao)慮到有充(chong)足空(kong)間，為完成自動化(hua)(hua)技術計劃方(fang)案奠定(ding)基礎。

電(dian)纜線(xian)(xian)(xian)(xian)截(jie)(jie)(jie)面(mian)的(de)挑選，關聯到項(xiang)(xiang)目投(tou)資是多少、路(lu)線(xian)(xian)(xian)(xian)的(de)耗損和工作(zuo)(zuo)電(dian)壓(ya)(ya)品(pin)質(zhi)、電(dian)纜線(xian)(xian)(xian)(xian)的(de)使(shi)用(yong)期(qi)等。如(ru)采用(yong)截(jie)(jie)(jie)面(mian)偏小，會造成 工作(zuo)(zuo)電(dian)壓(ya)(ya)品(pin)質(zhi)降低、路(lu)線(xian)(xian)(xian)(xian)耗損過(guo)大，則會使(shi)前期(qi)項(xiang)(xiang)目投(tou)資太(tai)高。因(yin)而應依(yi)據負(fu)載(zai)預測(ce)分析結(jie)果，建設規劃，挑選適(shi)合的(de)截(jie)(jie)(jie)面(mian)，使(shi)電(dian)線(xian)(xian)(xian)(xian)電(dian)纜考(kao)慮工作(zuo)(zuo)中(zhong)(zhong)電(dian)流量下的(de)纜芯溫(wen)度規定和電(dian)流規定，短路(lu)容(rong)量功效下的(de)熱(re)平穩規定。因(yin)為負(fu)載(zai)預測(ce)分析工作(zuo)(zuo)執(zhi)行力性(xing)強(qiang)、性(xing)較(jiao)低，因(yin)而，挑選電(dian)纜線(xian)(xian)(xian)(xian)截(jie)(jie)(jie)面(mian)時，也要(yao)(yao)考(kao)慮《城市中(zhong)(zhong)低壓(ya)(ya)配電(dian)網改(gai)造技術導則》和《城市電(dian)力網規劃導則》規定。在三相(xiang)四線(xian)(xian)(xian)(xian)制(zhi)底壓(ya)(ya)電(dian)力網采用(yong)電(dian)線(xian)(xian)(xian)(xian)電(dian)纜時，也要(yao)(yao)考(kao)慮到零線(xian)(xian)(xian)(xian)截(jie)(jie)(jie)面(mian)的(de)挑選，在公(gong)共底壓(ya)(ya)互聯網中(zhong)(zhong)，因(yin)為受(shou)客戶要(yao)(yao)素(su)危害很大，三相(xiang)負(fu)載(zai)均(jun)衡無(wu)法操縱，為改(gai)進工作(zuo)(zuo)電(dian)壓(ya)(ya)品(pin)質(zhi)，減少線(xian)(xian)(xian)(xian)損，零線(xian)(xian)(xian)(xian)截(jie)(jie)(jie)面(mian)應與(yu)相(xiang)線(xian)(xian)(xian)(xian)截(jie)(jie)(jie)面(mian)同樣。
