1. Application

    Low-smoke and halogen-free wires and cables can produce very little smoke, and the gas released has no halogen and are non-toxic (with low toxicity). It can reduce damages to apparatus, equipment and humans dramatically and are widely used in hospitals, high buildings, large-scale library, gym, waiting room and other place with high-density population.

    The plastic insulated wires and cables we produced meet the requirements of GB/T 12706-2008, GB 5023-2008, GB/T 9330-2008 and DJ 08-93-2002. Also our products can be categorized into flame-retardant series, fire-resistant series, etc.

3. Grade-classification & Application
1) Low-smoke free/low-halogen model divides into four kinds:special class,first class,secondclass,third class according to the propety, fire damage and evacuation & extinguishment difficulty. Meanwhile, it also complies with the requirement of Table3-2
2) When they are laying in colligation, the low-smoke free/low-halogen wires and cablesshould be flame-retardant types that 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 resistant types.
