耐火電力電纜
FLAME-RESISTANT POWER CABLE
簡介
BRIEF INTRODUCTION
耐火電纜就是在火焰燃燒情況下能夠保持一定時間安全運行的電纜。耐火電纜適用于高層建筑、油田、電站、電廠、礦山、化工、地鐵等要求防火安全條件高的場合,又是應急電源、消防泵、電梯、通訊信號系統的理想電纜。
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.
