架空絕緣線

中文名稱：架(jia)空絕緣(yuan)線

英文名(ming)稱：Aerial insulation line

架空線(xian)定義(yi)：單層或多層鋁股線(xian)絞合在上(shang)面擠(ji)制絕緣層的導(dao)線(xian)

所(suo)(suo)謂(wei)架空(kong)線(xian)(xian)(xian)是相對(dui)電纜(lan)說的(de)，就(jiu)是由(you)桿塔將導(dao)(dao)線(xian)(xian)(xian)架設在一定高(gao)度傳輸電能的(de)線(xian)(xian)(xian)路(lu)。對(dui)于(yu)(yu)高(gao)壓輸配電網架空(kong)線(xian)(xian)(xian)的(de)對(dui)地絕緣一般是靠空(kong)氣的(de)，之(zhi)前的(de)配電線(xian)(xian)(xian)路(lu)（10kV一下除380V）一般也采(cai)用裸導(dao)(dao)線(xian)(xian)(xian)，但由(you)于(yu)(yu)市區配電環境(jing)復雜，常(chang)常(chang)發生(sheng)短路(lu)接地及雷(lei)擊線(xian)(xian)(xian)路(lu)的(de)情況，導(dao)(dao)致供(gong)電可靠性降低，所(suo)(suo)以目般10kV以下架空(kong)線(xian)(xian)(xian)路(lu)都采(cai)用絕緣導(dao)(dao)線(xian)(xian)(xian)（即(ji)導(dao)(dao)線(xian)(xian)(xian)外層包裹絕緣層），這(zhe)就(jiu)是所(suo)(suo)謂(wei)的(de)絕緣架空(kong)線(xian)(xian)(xian)

架空(kong)(kong)線(xian)(xian)有(you)低(di)壓和高(gao)壓之分，一般(ban)型號分為(wei)很多種，比如路燈架空(kong)(kong)線(xian)(xian)來說，JKLYJ*10KVA*50*100，就說明了架空(kong)(kong)線(xian)(xian)的(de)電壓，型號，材質，芯的(de)截面積和長(chang)度。重慶架空(kong)(kong)線(xian)(xian)纜(lan)。樂山架空(kong)(kong)線(xian)(xian)纜(lan)，梁(liang)平架空(kong)(kong)線(xian)(xian)纜(lan)，綿陽(yang)架空(kong)(kong)線(xian)(xian)纜(lan)，武隆架空(kong)(kong)線(xian)(xian)，綿陽(yang)架空(kong)(kong)線(xian)(xian)，江北架空(kong)(kong)線(xian)(xian)，

      架空絕緣電(dian)(dian)纜主要應用于城市(shi)和林(lin)區電(dian)(dian)網改造中，該產品(pin)結構簡單(dan)，使用安全(quan)，具(ju)有優(you)良(liang)的機(ji)械、物理性(xing)能(neng)和電(dian)(dian)氣(qi)性(xing)能(neng)。耐電(dian)(dian)痕、耐沿面放電(dian)(dian)、耐大氣(qi)性(xing)能(neng)優(you)良(liang)。同時架空電(dian)(dian)纜用于市(shi)郊長距離送電(dian)(dian)時，電(dian)(dian)纜電(dian)(dian)感(gan)值很低，線路壓降小(xiao)，不要增加升壓措施，有很高的經(jing)濟效益。

2、使用特性

2.1電纜長期允許(xu)高工作溫度 （PVC）、（PE）絕緣應不超過70℃； 交聯絕緣（XLPE）應不超過90℃。

2.2短(duan)路時（長(chang)持續時間不(bu)超過5s）導(dao)體高(gao)溫度（PVC）絕緣(yuan)應不(bu)超過130℃； 聚(ju)乙(yi)烯（PE）絕緣(yuan)應不(bu)超過150℃； 交聯絕緣(yuan)（XLPE）應不(bu)超過250℃。
