阻燃型电缆除上述标准外, 其阻燃性能按GA306.1-2001标准规定范围A、B、C三种不同的阻燃类别和I、II、III、IV四个级别, A类别的阻燃型最优用户可根据选用。
耐火型电缆的耐火性能按GA306.2-2001标准注定分成A、B两种不同的耐火型(950摄氏度——1000摄氏度/90min, 750摄氏度——800摄氏度/90min)和I, II,III,IV四个级别,
用户可根据使用场合及要求选用。
2 产品特点及用途
聚录乙烯绝缘和护套控制电缆适用于交流额定电压U0/U为450/750及以下控制、监控回路及保护线路等场合, 作为电气装备之间的控制接线。
阻燃型控制电缆的主要特点是不易着火或着火时延燃仅局限在一定范围内, 适用于对阻燃性能要求较高的场合。
耐火型控制电缆的主要特点是电缆除了能在正常的工作条件下传输电力外, 电缆在着火燃烧仍能保持一定时间的正常运行, 适用于对耐火特性有要求的场合。
3 电缆的长期允许工作温度为70℃
