Low-smoke, halogen-free (low halogen) wire and cable produce very little smoke during flame combustion, and the released gas does not contain halogen (low halogen) elements, and is non-toxic (low toxicity). When a fire occurs, it can greatly reduce the harm to instruments, equipment, and human body, and is therefore widely used in high-rise buildings, hospitals, large libraries, sports venues, disaster prevention and control command buildings, stations, civil airports, passenger waiting rooms, key cultural relics protection places, underground subways, underground shopping malls, or densely populated public places.
The plastic insulated wires and cables with rated voltage of 35KV and below developed and produced by our company not only meet the performance requirements of GB/T12706-2002, GB5023-1997, GB9330-88, and DJ08-93-2002, but also have formed a series, namely flame-retardant type, fire-resistant type, especially the low-smoke halogen-free (low halogen) performance meets the national standards GB/T17650-1-2-1998, GB/T17651. 1-2-1998, and has been verified by the national first-level scientific and technological inspection. This type of product has reached the domestic advanced level of similar products.
