Brief product introduction
Low-smoke free-halogen flame-retardancy wire cables can produces little smoke and inno cuousgas 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, itwas widely used in the crowded public concourses such as high-rise building, large-sized library,gymnasium, commanding&dontollingbuilding for guard against blast, station, ivil airfield, passenger waiting room,emplases cultural relic,subway,underground shop,etc.
The using property of the rated voltage under 3$k plastics insulated cable and wire developed by our company,comply with therequire-ment of GB/T12706-2008,G8 5023-2008 and GB9330-88,DGJ08-93-2002.Meanwhile, its low-smoke and free-halogen property complywiththe standard of GB/T19650-12-1998,GB/T17651.1~2-1998.B页天和national technique inquiry,this type of products reach to domestic advancedlevel,Lowsmoke free-halogen flame retardancy wire cables.

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 classaccording to theusingproperty, fire damage and evacuation&extinguishment difficulty,Meanwhile, it aslo complieswith the requirement of Table3-2.
2.When they are laying in colligation,the low-smoke free/low-halogen wires and cables should be flame-retardancyrypes whose grades comply with table 3-3and table 3-4. lf the location needs intergrated lines and constant electricity under the outside fire,they should be fire resistance types.
Table 2 the grade choice to the flameretardancy property of electrical wires
| Applicable place | Section area | Flame retardancy grade |
| Special class | 50mm²and above | B class |
| 35mm²and above | C class | |
| First class | 50mm²and above | C class |
