Abstract

The invention provides an anti-burn and anti-distortion cable based on flame-retardant inert gas, and relates to the technical field of cables. The invention discloses an anti-burn and anti-distortioncable based on flame-retardant inert gas. The device comprises an outer package, an inner cavity is formed in the outer package, a first fireproof coating is fixedly installed on the inner side of the outer package, an inner package is fixedly installed in the outer package, a connecting rod is fixedly connected between the inner package and the outer package, and a second fireproof coating is fixedly installed on the periphery of the inner package. The invention discloses an anti-burn and anti-distortion cable based on flame-retardant inert gas. Concentrated heating of internal wires is avoided, torsion generated by twisting can be buffered, the phenomenon that the wires are broken due to long-time excessive twisting is avoided, internal filling materials are saved, the flexibility of the cable is improved, the effect of fire on the cable is relieved, fusing of the internal wires is relieved, and time is bought for cutting off a cable power source.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an anti-burn and anti-torsion cable based on flame-retardant inert gas. Background technique [0002] A cable is made of one or more mutually insulated conductors and an outer insulating protective layer. It is a wire that transmits power or information from one place to another. It is usually a similar rope twisted by several or several groups of wires. Each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating covering layer. The cable has the characteristics of internal energization and external insulation. [0003] In the event of a fire, if the cable breaks, it will easily generate a discharge phenomenon, which will make the fire bigger and affect the power consumption in other areas. Therefore, the existing cables need to have anti-burn performance, while the traditional The cables are a...

Problems solved by technology

[0003] In the event of a fire, if the cable breaks, it will easily generate a discharge phenomenon, which will make the fire bigger and affect the power consumption in other areas. Therefore, the existing cables need to have anti-burn performance, while the traditional The cables are all wrapped with different flame-retardant materials for fire prevention, so that the flame will ignite the cable, but the internal wires will still withstand a high temperature. After the temperature reaches a certain level, the internal wires will still be fused, and During the installation and transportation of the cable, it is easy to twist, which makes the internal wires twisted and easily broken. In the traditional cable, the mutually insulated wires are attached to each other, and there is a large amount of backlog filling inside, which not only wastes raw materials, but also in the process of work. The heat generated by the wire is easy to accumulate, which accelerates the heating of the cable

[0004] In order to solve the above problems, the inventor provides an anti-burn and anti-twist cable based on flame-retardant inert gas, which avoids the concentrated heating of the internal wires, can buffer the torsion force generated by twisting, and avoids the occurrence of excessive twisting of the wires for a long time. The phenomenon of fracture saves the internal filling material, improves the flexibility of the cable, slows down the effect of the fire on the cable, alleviates the fusing of the internal wire, and buys time for cutting off the cable power supply
