A self-adaptive rigid-flexible double-state fireproof cable

Abstract

The invention discloses an adaptive rigid-flexible dual-state fireproof cable, which belongs to the field of cables. In the high-temperature environment of fire, the invention takes the lead in transferring the high temperature from the outside to the inside of the thermosetting filling liquid through the heat-conducting air filter soft wire, so as to promote the internal heating of the thermosetting filling liquid. The water is heated and evaporated, and the water molecules are transferred to the outside world through the heat-conducting air filter soft silk. After the thermosetting filling liquid loses water, it is sintered into a solid under the action of high temperature. , the water vapor evaporated to the outside plays a certain flame retardant effect on the fire environment outside the cable core. The cable core is effectively protected, and at the same time, the cable at this part changes from the original flexible state to a rigid state, which automatically realizes its own fire protection, and also facilitates the rapid judgment and detection of the damage of the present invention in a fire later.

Description

technical field [0001] The invention relates to the field of cables, and more specifically relates to an adaptive rigid-flexible double-state fireproof cable. Background technique [0002] The wire and cable industry is the second largest industry in China after the automobile industry. The product variety satisfaction rate and domestic market share both exceed 90%. As one of the most important cable product R&D and production bases in the world, China currently has Flame retardant, high temperature and low temperature resistance, low inductance and low noise, green environmental protection, low smoke and halogen-free, anti-ant and rodent, waterproof and moisture-proof, etc. A series of cable products with unique performance and special structure, and have formed a certain productive forces. With the continuous improvement of social security and system safety requirements, through the extensive publicity, promotion and cooperation of the government, industry and enterprises...

Problems solved by technology

These two cables have been used in the market for many years, but with the development of the times and the advancement of science and technology, the cables in the existing technology can no longer meet the needs of the development of the modernization process, such as multi-core cables in skyscrapers, tunnels, airports and other places. The demand for long-length cables is increasing day by day. These places require cables to have a long fire resistance time, and the production with the original old technology can no longer meet the modern needs.

[0004] However, due to the hard texture of the steel fireproof cable, it is very inconvenient for the construction, and the bending degree of the flexible cable is also small. Because the inner insulation is made of magnesium oxide, it is easy to cause cracks in the inner insulation when bending. Therefore, in the prior art This kind of cable can no longer meet the needs of the development of the modernization process
