当人们要求电缆线路在发作火灾时能持续发挥作用,而且当电缆因为运用上的需求架设在高危区域的线路上时,电缆有必要具有耐火功能。一旦遇上火灾,此种耐火电缆仍能在必定时间内持续安全运转,为人员及设备的抢救供给电能。核电缆的耐火功能按运用要求不同,分一般耐火功能要求和特别耐火功能要求。特别耐火功能要求为:在对电缆碰击条件下进行1000% ,5min焚烧试验,火焰平息后持续碰击5min,一起用规则压力的高压水冲电缆,要求在整个试验过程中电缆能坚持持续通电。
360彩票网 美国1974年制定IEEE383电缆规范后,年发作核电厂电缆着火延燃事端,促进人们注重难燃性试验规范的严厉性问题。关于核岛用电缆制品,到达无卤/低烟/阻燃,即要求电缆制品能经过IEC332-3成束焚烧试验,焚烧烟浓度到达IEC1034-2的技能要求,焚烧腐蚀性气体到达IEC754-2规则的推荐值的要求,绝缘线芯经过IPCEAS-19-81规则的单根笔直焚烧试验。
