       低烟无（低）卤电线电缆在火焰燃烧情况下产生极少量烟雾，释放的气体不含卤（低卤）元素，无毒（低毒）。当火灾发生时，可大大减少对仪器、设备和人体的危害，因而被广泛应用于高层建筑、医院、大型图书馆、体育馆、防灾指挥调度楼、车站和民用机场、旅客候车室、重点文物保护场所以及地铁、地下商场或人口密集的公共场所。
        本公司开发生产的额定电压 35kv 及以下塑料绝缘电缆电线，其使用性能不及符合gb/t12706-2002、gb 5023-1997和 gb 9330-88、dj08-93-2002规定要求，并且已形成系列，即阻燃型、耐火型，特别是低烟无卤（低卤）性能符合国家标准 gb/t17650-1-2-1998、gb/t17651.1-2-1998，经国家一级科技查新，该类产品达到同类产品的国内先进水平。

        low-smoke free-halogen flame-retardancy wire cable can prodces little smoke and inno cuousgas without halogen or with little halogen when combustion. it can extremely reduce the damage to the instruments, equipment an body as the fire occurred,so,it was widely used in the crowded public concourses such as high-rise building,large-sized library, gymnasium,commanding&controlling building foe guard against blast, station,civil airfield，passenger waiting room, emphases cultural relic,subway,underground shop,etc.
        the using property of the rated voltage under 35kv plastics insulated cable and wire developedby our company, comply with the requirement of gb/t12706-2002、gb 5023-1997 and gb 9330-88、dj08-93-2002. meanwhile,its low-smoke and free-halgen propery comply with the standard of gb/t17650-1-2-1998、gb/t 17651.1-2-1998.by the national technique inpqity,this type of productsreach to domestic advanced level.lowsmoke free-halogen flame-retardancy wire cables.

二、产品的型号、名称见表1   the type and its specification see table 1

三、产品使用场所的分级及应用   grade and choose for the using location

1. 低烟无(低)卤使用场所应根据建筑物的使用性质、火灾危险性、疏散和扑救难度等分为特级、一级、二级、三级。
2. 低烟无(低)卤电线电缆成束缚设时，采用阻燃电线电缆，阻燃级别选择应符合表2、表3，在外部火势作用下，需保持线路完整性、维持通电的场所，其线路应采用耐火电线电缆。
1. low-smoke free/low-halogen types divides into four kindsapecial class,first class,second class,third class accordinto the using propety,fire damage and evacuation&extinguishmentdifficulty.meanwhile,it also complies with the requirement of table 3-2.
2. when they are laying in colligation,the low-smoke free/low-halogen wires and cables should be flame-retardancy types whose grades comply with tables3-3 and table3-4.if the location needs integrated lines and constant electricity under the outside fire. they should be fire resistance types.
