    電線電纜用以傳輸電(磁)能,信息和實(shí)現(xiàn)電磁能轉(zhuǎn)換的線材產(chǎn)品,廣義的電線電纜亦簡稱為電纜。電纜的種類比較多,今天我們來講講低壓電纜在實(shí)用過程中都應(yīng)有哪些特點(diǎn)。⒈敷設(shè)的隨意性比較大,路徑不是很明白。⒉敷設(shè)時(shí)不像高壓電纜那樣填沙加磚后深埋,相反埋...

    耐火電線電纜,目前從制作工藝角度來說,分為兩大類:一種是以云母帶繞包為主要防火手段的線纜。其特點(diǎn):生產(chǎn)長度不受限制,安裝使用方便。另一種.以氧化鎂為主要防火手段的線纜。其特點(diǎn):成本較高,生產(chǎn)長度嚴(yán)格,安裝使用較為繁瑣。但從耐火性能來看,后者...
