The characteristics of fire prevention wire and cable
Flame retardant cable (Flame retardancy)-block, slow down the spread of Flame wire and cable, make fire do not expand(acsr conductor).
Refractory (Fire resistance)-in the flame cases can keep a certain time of the operation, that is, keep the integrity of the line (Circuit integrity).
Halogen-free (Free halogen)-a wire and cable material does not contain the halogen, the combustion products low corrosion.
Low brine (Low halogen)-a wire and cable material can contain halogen, but the content is Low.
The Low smoke (Low smoke)-cable burning of smoke less, namely pervious to light rate is higher(Aluminum sheet).
LOW toxicity (LOW toxicity)-wire cable material burning gas LOW toxicity.
Our country flame retardant and refractory wire and cable research and development began in 1982. After five years, or 1987 years, many cable manufacturer has been put into production and accepted for the user. According to the characteristic of combustion was named after the confusion and model, the author puts forward the relative test method with burning wire and cable should be the combustion
characteristics, classification of the fire wire and cable, use Chinese pinyin first letters to finalize the design as the corresponding common wire and cable type of prefix. One of the model of flame-retardant wire cable and power cable ZR refractory of model NH already used toda
