　　用途：耐火电缆广泛应用于高层建筑、地下铁道、地下街、大型电站及重要的工矿企业等与防火安全和消防救生有关的地方，例如，消防设备及紧急向导灯等应急设施的供电线路和控制线路。 2.电缆敷设安装允许弯曲半径非铠装电缆应不小于电缆外径的10倍；铠装电缆应不小于电缆外径的15倍。

凡是装配过电气控制线路或控制柜的同行，想必都对不可或缺的“急停”按钮印象深刻。这种用在紧急情况下的按钮，多为红色蘑菇头自锁式，在整个控制系统中非常醒目。不少同行认为该按钮只是使用常闭触点串入电控系统的控制回路，在其按下后用以切断整个控制回路电源，使线路当中的各个线圈失电，间接控制主回路断电停机。但有时“急停”按钮的功能绝非上述那样简单，如果不结合生产实际情况，恐怕该“急停”按钮非但无法起到相应作用，还会造成不必要的事故。

　　（配线用）HJVV、HJVVP、HPVV通信电缆介绍：用于配线架至交换机或交换机内部各级机器间连接等（包括农村电话局用），线路的始端和终端，供连接市内电话电缆至分线箱或配线架之用，内导体线径（mm）：0.40、0.50、0.60、0.70、0.80、0.90对数（对）：5—1000HPVV低频通信配。
