What do you think a flame-retardant cable looks like? Does it not burn at all? This is not the case. Compared with ordinary cables, flame retardant cables have a relatively low combustion point and will not be out of control like ordinary cables. The following is a detailed explanation: When the wire and cable catch fire, the flame retardant cable can limit the combustion to the local scope and extinguish it within a certain period of time, without spreading, in order to protect various other equipment and avoid causing greater losses. Flame-retardant cable is a new type of flame-retardant cable developed in recent years according to the actual production needs. This product is suitable for fixed laying of flame-retardant requirements in power system. For example: cable tunnel, cable sandwich, main control room, command center and other important occasions.

As with ordinary cables, there is no difference in the structure of flame retardant cables. The difference is the insulation. For example, flame-retardant cables use self-developed environmentally friendly materials as insulation materials and do not contain any toxic substances, such as halogens. Therefore, they are also low in smoke and harmless. They have almost no smoke in the combustion process, no corrosive gases, more conducive to our escape in the event of a fire, and a safer guarantee for our lives.

According to the cable flame retardant combustion test standards and requirements, when the flame retardant cable is burned in bundles, the flame temperature exceeds 815℃, and the fire supply time is 40min. Its performance requirements are: after stopping the fire supply, the combustion should be extinguished naturally; Then wipe the sample, ignore any softening and deformation of non-metallic materials, and measure the carbonization (combustion) length of the sample shall not exceed 2500mm. Flame-retardant cable has the advantages of high purity, low oxygen content, high conductivity, good processing performance, smooth appearance, round surface, no burrs, cracks, peeling, defects and so on.

It can be seen that the flame-retardant cable is characterized by a small fire burning range and can be automatically extinguished. It's not that flame-retardant cables don't burn. When the current passes through the conductor, due to the existence of conductor resistance, it will cause the conductor to heat up, this phenomenon is called the thermal effect of the current.
