一、 產(chǎn)品特點(diǎn)及用途 Features and applications
聚氯乙烯絕緣聚氯乙烯護(hù)套電力電纜具有良好的電氣性和化學(xué)穩(wěn)定性，結(jié)果簡(jiǎn) 單， 使用方便。本產(chǎn)品適用于交流額定電壓U0/U為0.6/1kV及以下的輸配電電線路上。
阻燃電力電纜的主要特點(diǎn)是電纜不易著火或著火是延燃僅局限在一定范圍內(nèi)，適用于電纜敷設(shè)密集程度較高的發(fā)電站、地鐵、隧道、高層建筑、大型工礦企業(yè)、油田、煤礦等場(chǎng)所。
耐火電力電纜的主要特點(diǎn)是電纜除了能在正常的工作條件下傳輸電力外，電纜在著火燃燒時(shí)仍能保持一定時(shí)間的正常運(yùn)行，適用于核電站、地鐵、隧道、高層建筑等與防火安全和消防救生有關(guān)的地方。
PVC insulated and protective covered power cable,whose electirc property and chemical stability are excellent,is simple in structure and convenient in application.This manufactu is applicable to the transmission and supply line,of which the AC rated voltage Uo/U iS 0.6/1kV or lower level.
The flame-retardant power cable is not easily to catch fire and it can confine the fire in some limited area,therefore the cable is applicable to the places where the density of cable laying is high,such as generating station,subway,tunnel,high-rise building,large industrial and mining establishment,oil field,coal mine and so on.
The fire-resistant power cable is ,beside the power transmission under normal condition,can continue operating normally for some time when it catches fire,so it is applicable to the places which is concerned to the fire protection such as nuke,subway,tunnel,high-rise building and so on.
