1. Application
Low-smoke free-halogen flame-retardancy wire cables can produces little smoke and innocuous gas without halogen or with little halogen when combustion. It can extremely reduce the damage to the instruments, equipment and body as the fire occurred. So, it was widely used in the crowded public places such as high-rise building, large-sized library, gymnasium, cannabding &controlling building for guard against blast, station, civil airfield, passenger waiting room, emphases cultural relic, subway, underground shop, etc.
The using property of the rated voltage under35KV plastics insulated cable and wire developed by our company, comply with the requirement of G/T12706-2002, GB5023-1997 and GB9330-88, DJ08-93-2002, Meanwhile, its low-smoke and free-halogen property comply with the standard of GB/T17650-1<<2-1998, GB/T17651.1~2-1998. By the national technique inquiry, this products reach to domestic advanced level. Low-smoke free-halogen flame-retardancy wire cables.

3. Grade and choose for the using location
1. Low-smoke free/low-halogen types divides into four kinds: special class, first class, second class, third class according to the using property, fire damage and evacuation & extingulishment difficulty. Meanwhile, it also complies with the requirement of Table3-2.
2. When they laying in colligation, the low-smoke free/low-halogen wires and cables should be flame-retardancy types whose grades comply with Table3-3 and Table3-4. If the location needs integrated lines and constant electricity under the outside fire, they should be fire resistance types.
