The importance of choosing flame retardant wires
In recent years, in power system fire accidents around the world, disasters such as power supply interruptions due to power cable fires have occurred from time to time and are on the rise. It can be seen that the selection of wires is particularly important, especially the use of flame-retardant wires in home decoration, which has become a popular choice.
Flame-retardant wires refer to wires with flame-retardant functions. They are widely used because of their ability to retard and delay flame combustion. They are mainly used for building decoration, lighting, power transmission and distribution. Their technical parameters are generally similar to ordinary wires. Compared with ordinary wires, flame-retardant wires are widely used. , flame retardant wires are more practical.

Three major principles for selecting flame retardant cables
1. First, the volume weight of non-metallic materials of wires or cables should be calculated, and the flame retardant category should be selected based on the initial flame retardant definition.
2. Flame-retardant cables must be marked with a flame-retardant grade. If not, it will be classified as Class C by default.
3. Since it is currently stipulated that the non-metallic content of Class A flame-retardant cables when laid in bundles shall not exceed 7L/m, for cables with larger cross-sections, only a few cables will exceed this regulation. At present, the solution is to divide it into several cable bundles for laying, or to install longitudinal partitions in the cable tray.
