Description

Technical Field

[0001] The present application relates to the technical field of fire-resistant and flame-retardant flexible cables, and in particular to a high-temperature resistant, flexible, environmentally friendly, fire-resistant and flame-retardant flexible cable. Background Art

[0002] In modern industry, construction and special environment applications, the performance requirements for cables are becoming increasingly stringent. Traditional cables often have difficulty in taking into account high temperature resistance, fire retardancy, flexibility and environmental protection. For example, in some high-temperature industrial sites, the insulation materials of ordinary cables may age and deform rapidly at high temperatures, resulting in a decrease in electrical performance and even safety accidents; in the event of a fire, if the cable does not have good fire retardancy, it will not only be easily burned, but also become a medium for the spread of fire, aggravating the fire hazard; at the same time, with the enhancement of environmental awareness, the harmful gases and substances generated by cables during use are also receiving more and more attention. Therefore, it is of great practical significance to develop a soft cable that is both resistant to high temperatures and has good flexibility and environmental protection and fire retardancy.

[0003] For example, the patent with the publication number "CN205318870U" and the patent name "A three-core ultra-flexible cable" discloses that "the utility model relates to the field of cable technology, specifically to a three-core ultra-flexible cable, including a cable core and an insulating layer, a filling layer and a sheath wrapped around the cable core from the inside to the outside in sequence, the cable core is provided with three, each of the cable cores includes a plurality of twisted wire groups, each twisted wire group is formed by a bundle of ultra-fine wires arranged in the center and 6 bundles of ultra-fine wires surrounding the center, each bundle of ultra-fine wires is formed by irregular twisting of multiple ultra-fine copper wires; the diameter of the cross section of each ultra-fine copper wire is set to 0.03-0.10mm. Compared with the prior art, the cable of the utility model, on the one hand, adopts ultra-fine wires with a diameter of 0.03-0.10mm, so that the cable core has better flexibility, and on the other hand, the cable adopts the above-mentioned layer-twisted structure, which improves its overall flexibility. The tensile strength is as high as 15.8MPa and the elongation at break is as high as 186% after testing.

[0004] However, this patent cannot improve the flame retardancy of the cable at high temperatures. Therefore, those skilled in the art provide a high temperature resistant flexible environmentally friendly fireproof flame retardant soft cable to solve the problems raised in the above background technology. Summary of the invention

[0005] In order to solve the problems raised in the above background technology, the present application provides a high temperature resistant flexible environmentally friendly fireproof and flame retardant soft cable.

[0014] In summary, the present application includes the following beneficial technical effects: by providing a protective sleeve and a thin hose 2, the protective sleeve is made of a high temperature resistant silicone rubber material with a thickness of 0.5-1.5 mm. After the silicone rubber material continuously works for 1000 hours at a high temperature of 200°C, the insulation performance retention rate is not less than 80%, and it can play a good flame retardant effect. Even if the protective sleeve is damaged, a coolant is provided inside the thin hose, and the coolant can block the fire source.
