對于電線電纜的阻燃處理，要將電纜用絕熱耐燃材料包扎，亨通光伏電線，當電纜周圍著火時，包扎的電纜被絕熱耐燃材料與火隔離就可以避免遭燒毀。如果電纜自身著火，因包扎體內缺少氧氣可使火自熄，避免火勢蔓延到包扎體外。再就是要將電纜穿過墻壁、盤底、豎井的孔洞，用耐火材料封堵嚴密，防止電纜著火時，高溫煙氣擴散和蔓延造成火災面擴大。還需要在電線電纜的表面涂刷防火涂料，并用防火包帶將電纜需防燃的部位纏包。

電線單股(gu)和(he)多股(gu)的區別

單股電線(xian)(xian)的每一(yi)(yi)根(gen)(gen)(gen)電線(xian)(xian)，是由(you)單一(yi)(yi)的一(yi)(yi)根(gen)(gen)(gen)粗電線(xian)(xian)組(zu)成(cheng)的，又(you)叫做硬線(xian)(xian)；而多股電線(xian)(xian)的每一(yi)(yi)根(gen)(gen)(gen)電線(xian)(xian)，則是由(you)多個(ge)細銅絲組(zu)成(cheng)的一(yi)(yi)根(gen)(gen)(gen)電線(xian)(xian)，又(you)叫做軟線(xian)(xian)。

家裝電線(xian)型號(hao)單(dan)支導(dao)體(ti)硬線(xian)有WDZ-BYJ和BV兩種型號(hao)：

多(duo)股絞合(he)軟線有WDZ-BYJ、BVR、RV三種型號：

WDZ-BYJ：低(di)煙無鹵交(jiao)聯聚(ju)烯烴電線（根據導體結果不同，分硬線和軟線）

BV：PVC電線(xian)，只有一根銅線(xian)的單芯線(xian)比(bi)較硬

BVR：PVC電線(xian)，好多股銅絲絞在一起的單芯(xin)線(xian)

較(jiao)軟RV：PVC電線，更(geng)多股銅(tong)絲絞在(zai)一起的單芯線
