電纜基本絕緣水平

2021-11-30  來自: http://www.jiayandianzi.com/Product-index.html 瀏覽次數:195

  電纜每一電導體與屏蔽掉或金屬材料護線套中間的雷擊沖擊性承受工作電壓最高值,即基本上絕緣層水準要求。220kV及之上電纜線路的雷擊沖擊性承受工作電壓有兩個標值,可依據高壓避雷器維護特性,電纜線路單脈沖波特性長短及其相接機器設備雷擊沖擊性絕緣層水準等要素選擇。

  電纜種類(1)交聯聚乙烯和油紙電纜絕緣性能能較為?;瘜W交聯油紙絕緣層電纜具備電氣設備特性,使用期限較長的優勢,一般場所下均可應用。但油紙電纜與交聯聚乙烯電纜對比,其生產制造安裝工序較為復雜,成本費較為高。以介電損耗小的紙塑復合型絕緣層和抗老化特性優良的烷基苯合成機油為絕緣層構造的油式電纜,適用220kV及之上額定電壓。除此之外,油紙絕緣層電纜還適用髙壓直流輸電線路。

 ?。?)在110KV及下列電纜線路,一般以交聯聚乙烯(XLPE)絕緣層電纜為種類。1kV及下列配電設備電纜,除負載比較輕的線路可采用聚乙烯(PVC)絕緣層電纜外,也應取用交聯聚乙烯絕緣層電纜。注:現階段,1-500電纜關鍵選用交聯聚乙烯電纜,油紙絕緣層電纜,油式電纜僅余一些總量。
