      BTGYR柔性防火電纜

      BTGYRZ柔性防火電纜用途: 適用于適用于工業裝置、建筑物、構筑物及其附屬設施配電用固定敷設具有較高防火、耐火要求的額定電壓1kV(Um=1.2kV)電力電纜。

      BTGYRZ柔性防火電纜:

      一、BTGYRZ柔性防火電纜產品執行標準:Q/HL-2015-08


      二、BTGYRZ柔性防火電纜用途:

      適用于適用于工業裝置、建筑物、構筑物及其附屬設施配電用固定敷設具有較高防火、耐火要求的額定電壓1kV(Um=1.2kV)電力電纜。


      三、使用特性:

      1、額定電壓U0/U:450/750V、0.6/1kV

      2、長期使用工作溫度:

      YTTW型長期使用工作溫度200℃,短時(90min)工作溫度1000℃。

      BTLY、BTLV型長期使用工作溫度105℃,短時(90min)工作溫度1000℃。

      FA-BTGYRZ、FA-BTLHYZ型長期使用工作溫度90℃,短時(90min)工作溫度1000℃。


      3、電纜的敷設溫度:

      具有聚氯乙烯護套、聚烯烴護套的電纜,安裝時的環境溫度不宜低于0℃。

      YTTW型電纜敷設時最低環境溫度:固定敷設-60℃,非固定敷設-20℃。


      4、電纜的運行彎曲半徑

      非鎧裝電纜不小于電纜外徑的的10倍,鎧裝電纜不小于電纜外徑的的15倍。


      5、其他特性:

      1、按GB12666.6

      A. 類在火焰溫度950℃中燃燒,相間及相與外護套之間施加750V電壓,歷時90min絕緣不損壞。

      B. 類在火焰溫度750-800℃中燃燒相間及相與護套之間施加750V電壓,歷時90min絕緣不損壞。

      2、按英國BS6378標準,柔性防火電纜能滿足以下要求:

      A. 級650℃ 3h

      B. 級750℃ 3h

      C. 級950℃ 3h

      S. 級950℃ 20min

      絕緣不損壞。

      3、安全性好,防火電纜能在火焰中正常供電,起動滅火設備,減少火災損失,對人身安全也特別可靠,其銅護套是優良導體,是最好的接地PE線,且連續到電纜全長,大大提高了接地保護靈敏度與可靠性;

      4、使用壽命長,無機絕緣材料耐溫高,且不易老化,他的壽命比有機絕緣電纜高許多倍,在正常工作狀態下,其壽命可以與建筑物等同;

      5、柔性防火電纜的運輸和安裝包括安裝配件近似于普通電纜,較簡單;

      6、經濟性好,柔性防火電纜由于制作工藝先進,安裝簡單,在同等條件下其綜合費用比礦物絕緣電纜的費用明顯降低。
