架空導(dǎo)線
架空導(dǎo)線 :
■應(yīng)用
輸電線路上最常用的一種導(dǎo)線。由硬圓鋁線及鍍鋅鋼線組合絞制而成。也可在鋼芯及鋁線上凃防腐材料,稱為防腐鋼芯鋁絞線。主要用在沿海及化工等對(duì)導(dǎo)線具有嚴(yán)重腐蝕性氣氛的地區(qū),可提高導(dǎo)線的使用壽命
在近代電網(wǎng)中,超高壓線路均采用分裂導(dǎo)線,使導(dǎo)線在線路建設(shè)中的比例增大。我公司已可生產(chǎn)1400mm2的鋼芯鋁絞線,主要用作500KV變電所的軟母線。外徑為51mm.
■標(biāo)準(zhǔn)
符合標(biāo)準(zhǔn)GB/T 1179-2008:圓線同心絞架空導(dǎo)線。(IEC61089,MOD)
