交流電力線指的是配電工程中的低壓電力線。一般選擇的 依據(jù)有以下四種： 1)按機械強度允許的導(dǎo)線最小截面選擇 2)按允許溫升來選擇 3)按經(jīng)濟電流密度選擇 4)按允許電壓損失選擇 通信中常用的主要是低壓動力線，因其負(fù)荷電流較大，一般 應(yīng)按照發(fā)熱（溫升）條件來選擇。因為如果不加限制的話， 導(dǎo)線 的絕緣就會隨溫度升高迅速老化和損壞，嚴(yán)重時會引發(fā)電氣 火災(zāi)。 對于220v單相交流電 1：i＝p/220〔p為所帶設(shè)備功率〕 2：電源線面積s＝i/2.5（mm2） 對于380v三相交流電 1：i=p/(380*γ3*功率因數(shù)） 2：相線截面積s相=i/2.5（mm2） 3：零線截面積s零=1.7×s相 絕緣導(dǎo)線載流量估算 估算口訣： 二點五下乘以九，往上減一順號走。 三十五乘三點五，雙雙成組減點五。 條件有變加折算，高溫九折銅升級。 穿管根數(shù)二三四，八七六折滿載流。

針對不同規(guī)范對電線電纜截面積的不同要求展開討論。電線電纜及其導(dǎo)體標(biāo)準(zhǔn)明確對截面積不做考核,僅作為參考。而建筑節(jié)能方面標(biāo)準(zhǔn)簡單地將標(biāo)稱值等同于標(biāo)準(zhǔn)值,使得實際上滿足產(chǎn)品標(biāo)準(zhǔn)的電線電纜,應(yīng)用到建筑節(jié)能工程中反而被判為不合格,所以在建筑節(jié)能規(guī)范中應(yīng)剔除對截面積的硬性要求,改為參考值。
