电线电缆的绝缘和护套一般是由塑料或橡胶制成,具有易燃性。当电缆在过载、短路、局部过热等故障状态及外热作用下就会引起绝缘材料绝缘电阻下降、失去绝缘能力、甚至燃烧,引发火灾事故。
电线电缆密集铺设的场所,极易引起火灾。电缆的火灾一旦发生,其火势猛烈,同时产生大量浓烟和有毒气体,因扑救困难,往往造成重大的经济损失,严重威胁人们的生命和财产安全。
电线电缆
防火测试
为了减少和避免电线电缆火灾事故的发生,线缆所要求达到的阻燃性能级别也比较严格。电线电缆防火测试一般包括单根燃烧,成束燃烧,烟雾密度,烟雾毒性等。使用场所、火灾危险性、疏散和扑救难度不同,适用标准不同,不同国家的要求也有所差异。比如,轨道交通工具载客数量多,火灾风险大且逃生时间长,所以要求轨道交通用电线电缆达到的阻燃性能级别要求也非常严格。
