APPLICATION
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(yīng)急電源、消防泵、電梯、通訊信號系統(tǒng)的理想電纜。
Flame resistant cable is cable which can keep a certain period ofsafe operation when being burned.It applies to those places requiring high level fire-protecting conditions, such as high-rise buildings , oil fields, power stations, petrolchemincals and subways.In addition, it's an ideal cable for emergency supply , fire pump,electric elevator and communication symbol systems.
