Description

Technical Field

[0001] The utility model relates to the technical field of cables, and more specifically to a novel fireproof cable. Background Art

[0002] Traditional cables are mainly made of organic polymer materials such as plastics or rubber. These materials are flammable at high temperatures. Once they encounter a fire source, they can easily cause a fire. Moreover, these materials will release a large amount of toxic gas and smoke during the combustion process, which not only increases the hazard of the fire, but also causes great trouble to the rescue work and the evacuation of personnel. Therefore, in view of this, the existing structure and defects are studied and improved, and a new type of fireproof cable is provided, in order to achieve a more practical purpose.

At the same time, the ceramic insulation layer can improve the insulation performance and heat resistance of the cable, and the mica fireproof layer uses the excellent properties of the mica material itself, such as high temperature resistance and fireproof performance, to achieve fire protection for cables or other protected objects. When encountering high-temperature flames, the mica fireproof layer will expand rapidly and release moisture to form a protective layer, making the surface of the protected object difficult to burn, thereby achieving a fireproof effect. The internal armor layer and the external armor layer make the cable more sturdy, wear-resistant, and extrusion-resistant outer layer material, protecting the cable from external physical damage and reducing the risk of fire.
