Flame retardant cable is a kind of cable with flame retardant performance. Its main function is to prevent the spread of fire and protect the safety of people and property when a fire occurs. The working principle of flame retardant cable is mainly achieved through its special material and structural design.

First of all, the outer sheath of flame-retardant cables is usually made of flame-retardant materials, such as polyvinyl chloride (PVC) flame-retardant materials, polyethylene (PE) flame-retardant materials, etc. These materials have good flame-retardant properties and can prevent the spread of flames when a fire occurs, reducing the losses caused by the fire. In addition, the insulation layer and conductor of the flame-retardant cable are also made of flame-retardant materials, which further improves the flame-retardant properties of the cable.

Secondly, the structural design of flame-retardant cables also plays a key role. Flame-retardant cables usually adopt a multi-layer insulation structure, including conductors, insulation layers, shielding layers and outer sheaths. This multi-layer structure can effectively isolate the current, reduce cable heating, and reduce the risk of fire. In addition, flame-retardant cables also use special insulation materials and conductor designs to improve the high temperature resistance of the cable, ensuring that the cable will not short-circuit or leak electricity when a fire occurs, further reducing the hazards of fire.

Finally, flame-retardant cables also have a self-extinguishing function. When a fire occurs, the flame-retardant material of the flame-retardant cable will release a large amount of inert gas to form a protective film to prevent the spread of the flame. At the same time, the insulation layer and conductor of the flame-retardant cable will also cool down quickly, reducing the heat of the fire and preventing the fire from expanding. This self-extinguishing function effectively protects the cable and surrounding equipment and reduces the losses caused by the fire.

In general, the working principle of flame-retardant cables is to prevent the spread of fire and protect the safety of people and property through their special materials and structural design. Flame-retardant cables are widely used in construction, subways, ships and other fields, playing an important role in social security and stability. It is hoped that through continuous research and innovation, the performance of flame-retardant cables can be further improved to provide more reliable protection for people's lives and work.
