MC380V矿用采煤机电缆供应商

                天津市电缆总厂橡塑电缆厂—耐火电缆介绍如下

             ：  

      产品详细信息                                                            

       本产品适用于交流额定电压0.6/1KV及以下的地铁、高层建筑、商场、剧院、发电站、化学工厂、城市广场及其他公用事业等对电缆阻燃特性要求高的场合。电缆的无卤低烟、低卤低烟特性，当火灾发生时，蔓延速度慢，烟浓度低，可见度高，有害气体释放量小，便于人员撤离。燃烧气体的腐蚀性小，也避免了对仪器设备的损害，低卤、无卤的特性，使得电缆材料在耐老化和耐紫外线及其它辐照性能大大提高，从而延长电缆的使用寿命。

      使用特性                                                              

      1.电缆额定电压UO/U:600 /1000V，交流聚烯烃UO/U为0.6/1KV                                     

      2.电缆*工作温度为:-20℃－90℃，-40℃－105℃                                           

      3.*弯曲半径:无铠装电缆应不小于电缆外径的6倍，有铠装或铜带屏蔽结构的电缆应不小于电缆外径的12倍。
