WDZBN-RYJS低煙無鹵電纜有哪些特性

一,WDZBN-RYJS低煙無鹵電纜,阻燃性能優越,燃燒時煙度甚少,無腐蝕性氣體逸出,廣泛應用于核電站、地鐵車站、電話交換機及計算機控制中心、高層建筑大樓、賓館、廣播電視臺、重要軍事設施、石油平臺等,以及人員較集中,空氣密度低的場所。

二,產品特性:

1.電纜額定電壓UO/U:450/750V, /U為0.6/1KV , 300/500V。


2.電纜長期工作溫度為:-20℃-90℃,-40℃-105℃


3.推薦彎曲半徑:無鎧裝電纜應不小于電纜外徑的6倍,有鎧裝或銅帶屏蔽結構的電纜應不小于電纜外徑的12倍。


4.抗張強度比一般PVC電線大:一般PVC電線抗張強度大于1.05Kgf/mm2,而低煙無鹵電線抗張強度大于1.2Kgf/mm2;


5.具有良好的耐候性(-30℃~105℃);


6.具備良好的柔軟度(硬度為80—90);


7.具有非移性(因為此產品配方中不用添加可塑劑,故不會有移形性);


8.燃燒時不會產生有毒黑煙(會產生少量白色煙霧);


9.具有較高的體積電阻率:PVC電線一般為1012~1015Ω/cm3,低煙無鹵電線大于1016Ω/cm3;


10.具有良好的耐高壓特性:PVC電線一般耐10KV以上,而低煙無鹵電線高達15KV以上
