简介
BRIEF INTRODUCTION
耐火电缆就是在火焰燃烧情况下能够保持一定时间安全运行的电缆。耐火电缆适用于高层建筑、油田、电站、电厂、矿山、化工、地铁等要求防火安全条件高的场合,又是应急电源、消防泵、电梯、通讯信号系统的理想电缆。
Flame resistant cable can keep a centain period of safeoperationwhen being burned. It appliesto places requiring high level fire-protecting conditions, such as high-rise buildings, oil fields,power stations, petrolch-emincals and subways.In addition, it'sideal for emergency supply, fire pump, electric elevator and communication symbol systems.
