架(jia)(jia)空(kong)絕(jue)緣線(xian)(xian)是指由(you)電(dian)線(xian)(xian)桿、電(dian)塔等(deng)設施架(jia)(jia)設在(zai)高空(kong)中(zhong)用以電(dian)流(liu)(liu)傳輸的電(dian)線(xian)(xian)，架(jia)(jia)空(kong)絕(jue)緣線(xian)(xian)由(you)于(yu)常年(nian)暴露在(zai)室外，要面臨(lin)風吹日曬、雨雪侵蝕(shi)、雷電(dian)干擾等(deng)風險，因此對架(jia)(jia)空(kong)絕(jue)緣線(xian)(xian)的電(dian)流(liu)(liu)傳輸質量、護套使用壽命、抗老化、耐腐(fu)蝕(shi)等(deng)都有很(hen)高的要求，既要保證電(dian)流(liu)(liu)傳輸損耗低還保證一定的質量。架(jia)(jia)空(kong)絕(jue)緣線(xian)(xian)多用于(yu)遠距離電(dian)流(liu)(liu)傳輸、城市供電(dian)、工程工地(di)供電(dian)等(deng)領域(yu)。

       導線包含鋼(gang)芯(xin)(xin)(xin)鋁(lv)絞(jiao)線，擴徑鋼(gang)芯(xin)(xin)(xin)鋁(lv)絞(jiao)線，空芯(xin)(xin)(xin)導線，鋼(gang)鋁(lv)混絞(jiao)線，鋼(gang)芯(xin)(xin)(xin)鋁(lv)包鋼(gang)鉸(jiao)線，鋁(lv)包鋼(gang)鉸(jiao)線等，配電(dian)網關鍵選用(yong)架空絕緣線。

      初期(qi)空(kong)架配電設備(bei)路線(xian)(xian)(xian)一般選用裸導(dao)(dao)線(xian)(xian)(xian)，因為(wei)樹技，起重機，建(jian)筑工程(cheng)(cheng)施工，鳥(niao)等小動物觸碰(peng)導(dao)(dao)線(xian)(xian)(xian)，汽車碰(peng)撞電線(xian)(xian)(xian)桿，吊線(xian)(xian)(xian)，拋(pao)扔(reng)，風刮臟物等常常導(dao)(dao)致路線(xian)(xian)(xian)掉閘。伴隨著大城市(shi)的(de)發展(zhan)趨勢(shi)，很多在建(jian)的(de)房(fang)屋建(jian)筑間距有可能較近，因此(ci)執行空(kong)架配電設備(bei)路線(xian)(xian)(xian)絕緣(yuan)層化指配網發展(zhan)趨勢(shi)的(de)全過程(cheng)(cheng)。

       架空絕(jue)緣配電(dian)設備路(lu)(lu)(lu)線(xian)(xian)適(shi)用大城市人口密(mi)集地域，路(lu)(lu)(lu)線(xian)(xian)過道狹小，搭建裸(luo)導線(xian)(xian)路(lu)(lu)(lu)線(xian)(xian)與(yu)房屋建筑的(de)間隔無(wu)法達(da)到安全性規定(ding)的(de)區域及其(qi)景色綠化帶(dai)(dai)，防護(hu)林帶(dai)(dai)區和污濁(zhuo)比較嚴重(zhong)的(de)地方等。

      空架配(pei)電設備路線(xian)用絕緣(yuan)層(ceng)(ceng)(ceng)導(dao)(dao)線(xian)，按其(qi)結構(gou)形式一般分成髙壓(ya)(ya)(ya)分相式絕緣(yuan)層(ceng)(ceng)(ceng)導(dao)(dao)線(xian)，低電壓(ya)(ya)(ya)分相式絕緣(yuan)層(ceng)(ceng)(ceng)導(dao)(dao)線(xian)，低電壓(ya)(ya)(ya)貝塔(ta)射線(xian)式絕緣(yuan)層(ceng)(ceng)(ceng)導(dao)(dao)線(xian)，髙壓(ya)(ya)(ya)貝塔(ta)射線(xian)式半導(dao)(dao)體材料屏蔽(bi)掉絕緣(yuan)層(ceng)(ceng)(ceng)導(dao)(dao)線(xian)，髙壓(ya)(ya)(ya)貝塔(ta)射線(xian)式金屬材料屏蔽(bi)掉絕緣(yuan)層(ceng)(ceng)(ceng)導(dao)(dao)線(xian)。
