From the moment we were born, we have inextricably linked with firefighting. Personal safety has always been a major concern for us. We must try to avoid the occurrence of fires. Therefore, we must learn some basic knowledge in the family. Through the author's summary, it is found that most of the accidents caused by fires are caused by the aging of cables and the large amount of overload. Therefore, we must consider and understand the whole situation in a very low temperature state.
One of them is a flame-retardant cable. The cable has flame-retardant properties. The flame-retardant wire can provide more than 15 times the escape time than the non-flame-resistant wire. The halogen-free low-smoke cable halogen-free low-smoke cable should have no Halogen, low smoke and flame retardant properties, according to GB/T17650.2-1999 (halogen-free test) and GB/T17651.2-1998 (low smoke test), the index requirements are: pH 4.3, conductivity r10us / Mm, the minimum light transmittance is T60%. The material burned by the flame-retardant wire is only 1/2 of the non-flame-retardant wire, and the toxic gas produced by the combustion is only 1/3 of the non-flame retardant product, the smoke generation performance, the flame retardant product There is no significant difference from non-flame retardant products.
In terms of overall fire protection, the cable is very important for the overall safety of people. We must start from the fire itself, which is the greatest relief for us.
