本產(chǎn)品適用于0.6/1kv及以下的高層建筑物、地鐵、隧道、劇場、人防工程、石化企業(yè)等場所作輸配電線路或火災(zāi)報(bào)警設(shè)備、通信設(shè)備等應(yīng)急設(shè)施的供電線路及信號控制線路。電纜除低煙無鹵高阻燃特性外，還應(yīng)能處在火焰燃
燒中正常工作180min，當(dāng)火災(zāi)發(fā)生時(shí)，不發(fā)生短路和斷路故障，一直保障電力供給，維持系統(tǒng)運(yùn)行。并且燃燒時(shí)煙霧透光率高、毒性低，從而達(dá)到其防火安全和消防救生的功能。
　　It can be used not only to transmit and distribute  power on the power line of 0.6/1kv voltage or below  for high-rise building, subway, tunnel, theater, civil  air defense engineering, petrochemical system, but  also as power supply wire and signal control circuit  of emergency facilities such as power transmission  and distribution systems, fire alarm equipment and  communications equipment and so on. Besides  of features of LSZH and high flame resistance, it can also normally operate within 180min under the condition of flame burning. When the fire occurs, shor t-circuit and open circuit faults would not happen. It could endure continually supplying power and maintain the normal.
