隨著著電(dian)纜電(dian)線在配(pei)(pei)(pei)電(dian)網(wang)(wang)(wang)中的(de)(de)(de)不斷推廣營銷與運用(yong)，配(pei)(pei)(pei)電(dian)網(wang)(wang)(wang)可分為電(dian)纜互聯網(wang)(wang)(wang)技(ji)(ji)術(shu)(shu)(shu)和空(kong)架互聯網(wang)(wang)(wang)技(ji)(ji)術(shu)(shu)(shu)（含空(kong)架、電(dian)纜混和互聯網(wang)(wang)(wang)技(ji)(ji)術(shu)(shu)(shu)）。《關于〈城市中低壓配(pei)(pei)(pei)電(dian)網(wang)(wang)(wang)改造技(ji)(ji)術(shu)(shu)(shu)導則〉的(de)(de)(de)實施情況及補(bu)充(chong)(chong)意見》也(ye)對電(dian)纜變電(dian)設備(bei)(bei)互聯網(wang)(wang)(wang)技(ji)(ji)術(shu)(shu)(shu)自(zi)動(dong)化控制(zhi)明確指出了具體要求。因此，在配(pei)(pei)(pei)電(dian)網(wang)(wang)(wang)地(di)域互聯網(wang)(wang)(wang)技(ji)(ji)術(shu)(shu)(shu)采用(yong)電(dian)纜互聯網(wang)(wang)(wang)技(ji)(ji)術(shu)(shu)(shu)時(shi)，應(ying)按照配(pei)(pei)(pei)電(dian)自(zi)動(dong)化的(de)(de)(de)要求，采用(yong)新技(ji)(ji)術(shu)(shu)(shu)、新機(ji)械設備(bei)(bei)，有規(gui)范的(de)(de)(de)要充(chong)(chong)分考(kao)慮自(zi)動(dong)化控制(zhi)示范點，規(gui)范不成熟的(de)(de)(de)也(ye)要在服務設施機(ji)械設備(bei)(bei)型號規(gui)格挑選時(shi)，充(chong)(chong)分考(kao)慮有充(chong)(chong)裕室(shi)內空(kong)間，為進行(xing)自(zi)動(dong)化控制(zhi)方案打下基礎。

電(dian)纜(lan)橫(heng)(heng)截(jie)面(mian)的(de)(de)(de)選(xuan)(xuan)(xuan)擇，關系到投資項目(mu)多少錢、線(xian)(xian)(xian)路(lu)的(de)(de)(de)損耗和工(gong)作(zuo)頻(pin)率質量(liang)(liang)、電(dian)纜(lan)的(de)(de)(de)使(shi)用(yong)壽命等。如選(xuan)(xuan)(xuan)用(yong)橫(heng)(heng)截(jie)面(mian)偏小，會導(dao)致 工(gong)作(zuo)頻(pin)率質量(liang)(liang)減(jian)少、線(xian)(xian)(xian)路(lu)損耗過大(da)，則會使(shi)早(zao)期(qi)投資項目(mu)太高。因(yin)此應根據負(fu)荷預測分(fen)析剖析結果，整體規(gui)劃(hua)(hua)，選(xuan)(xuan)(xuan)擇合適的(de)(de)(de)橫(heng)(heng)截(jie)面(mian)，使(shi)電(dian)纜(lan)電(dian)線(xian)(xian)(xian)考(kao)慮到工(gong)作(zuo)中(zhong)(zhong)中(zhong)(zhong)電(dian)總流量(liang)(liang)下的(de)(de)(de)纜(lan)芯溫度要求(qiu)和電(dian)流量(liang)(liang)要求(qiu)，短路(lu)容量(liang)(liang)作(zuo)用(yong)下的(de)(de)(de)熱(re)穩定要求(qiu)。由于負(fu)荷預測分(fen)析剖析工(gong)作(zuo)執行力性(xing)強、性(xing)較(jiao)低(di)，因(yin)此，選(xuan)(xuan)(xuan)擇電(dian)纜(lan)橫(heng)(heng)截(jie)面(mian)時，還要考(kao)慮到《城(cheng)市中(zhong)(zhong)低(di)壓配電(dian)網改(gai)造技(ji)(ji)術(shu)導(dao)則》和《城(cheng)市電(dian)力網規(gui)劃(hua)(hua)導(dao)則》要求(qiu)。在三(san)相四線(xian)(xian)(xian)制底壓電(dian)力選(xuan)(xuan)(xuan)用(yong)電(dian)纜(lan)電(dian)線(xian)(xian)(xian)時，還要充(chong)分(fen)考(kao)慮零線(xian)(xian)(xian)橫(heng)(heng)截(jie)面(mian)的(de)(de)(de)選(xuan)(xuan)(xuan)擇，在公共性(xing)底壓互聯網技(ji)(ji)術(shu)中(zhong)(zhong)，由于受顧客(ke)因(yin)素傷(shang)害挺(ting)大(da)，三(san)相三(san)層交換機沒法控(kong)制，為改(gai)善工(gong)作(zuo)頻(pin)率質量(liang)(liang)，降(jiang)低(di)線(xian)(xian)(xian)損，零線(xian)(xian)(xian)橫(heng)(heng)截(jie)面(mian)應與相線(xian)(xian)(xian)橫(heng)(heng)截(jie)面(mian)一樣。
