耐熱合金-鋼芯鋁合金絞線

發(fā)布時(shí)間:2018-03-21 點(diǎn)擊量:1988

一、相關(guān)結(jié)構(gòu)
        鋼芯鋁絞線是由鋁線和鋼線絞合而成的,適用于架空輸電線路用。

它內(nèi)部是鋼“芯”,外部是用鋁線通過絞合方式纏繞在鋼芯周圍;鋼芯主要起增加強(qiáng)度的作用,鋁絞線主要起傳送電能的作用;
二、相關(guān)型號(hào)
       鋼芯鋁絞線的型號(hào)分為:JL/G1A JL/G1B JL/G2A JL/G2B JL/G3A
其中:G1A或G1B指的是普通強(qiáng)度鋼線。
G2A或G2B 指的是高強(qiáng)度鋼線。
G3A指的是特高強(qiáng)度鋼線。
型號(hào)差異:以JL/G1A-240/30型鋼芯鋁絞線為例。
在國標(biāo)(GB/T1179-2008)中以目前的JL/G1A-240/30表示;
在國標(biāo)(GB/T1179-1983)中以LGJ-240/30表示。
三、主要應(yīng)用
       對(duì)高電壓的輸電線路,由于線路的路徑有限,又不可能在一個(gè)路徑上架多條線路,人們想出了采用一個(gè)路徑,一套鐵塔,掛多條導(dǎo)線,即一條線路相當(dāng)于架了多條線路的方法;對(duì)500KV的輸電線路,我國大多采用掛四條導(dǎo)線的方式,這種架線的方式稱為同塔并架。
四、相關(guān)優(yōu)點(diǎn)
      鋼芯鋁絞線具有結(jié)構(gòu)簡單、架設(shè)與維護(hù)方便、線路造價(jià)低、傳輸容量大、又利于跨越江河和山谷等特殊地理?xiàng)l件的敷設(shè)、具有良好的導(dǎo)電性能和足夠的機(jī)械強(qiáng)度、抗拉強(qiáng)度大、塔桿距離可放大等特點(diǎn)。因此廣泛應(yīng)用于各種電壓等級(jí)的架空輸配電線路中。
五、技術(shù)條件
      1000平方毫米鋼芯鋁絞線技術(shù)將依托寧東—山東±660千伏直流輸電工程開展項(xiàng)目實(shí)施。公司開展一系列科研工作,綜合考慮電磁環(huán)境、機(jī)械性能、桿塔荷載、經(jīng)濟(jì)性等因素,認(rèn)為在寧東—山東工程中采用1000平方毫米鋼芯鋁絞線,具有多方面優(yōu)勢,可減少工程本體投資、降低運(yùn)營成本,是開展“兩型三新”輸電線路建設(shè),實(shí)施資產(chǎn)全壽命周期管理,推動(dòng)資源節(jié)約型、環(huán)境友好型社會(huì)建設(shè)的具體體現(xiàn)。
