適用范圍
Applications
本產(chǎn)品適用于交流額定電壓0.6/1KV及以下聚氯乙烯絕緣耐火電纜,要求電纜在著火情況下仍能保持一定時(shí)間繼續(xù)運(yùn)行的固定敷設(shè)場(chǎng)合。主要用于高層建筑、地下鐵路、核電站及重要工礦企業(yè)與防火安全和消防救生的地方,如應(yīng)急電源、戶內(nèi)消防設(shè)備、火災(zāi)報(bào)警設(shè)備、信號(hào)燈、通風(fēng)排煙設(shè)備、緊急用電梯等的供電線路。能有效地起到消防救生的目的,且由于電纜本身不會(huì)造成火災(zāi),可減少火災(zāi)發(fā)生的頻率及危害。
The product is used under 0.6/1KV,and can work properly for certain period of time even in fire.It is mainly used in high buildings,subways,nuclear station as well as safety devices,such as emergency power supply,fire-fighting equipment,fire alarming lights,elevator power lines.The cable will not burn even in the fire.
