Problems solved by technology

Shape memory alloy is currently the material with the best shape memory performance among shape memory materials; furthermore, the shape memory alloy layer will be deformed when heated, and the shape memory alloy layer arranged on the outer surface of the wear-resistant layer will expand after the wear-resistant layer is produced. , it will deform and wrap the wear-resistant layer, thereby improving the strength and impact resistance of the wear-resistant layer, and preventing the wear-resistant layer from softening when the wear-resistant layer is heated and deformed inside, thereby affecting the strength and stiffness of the wear-resistant layer; When a fire breaks out and the elastic base layer is damaged due to the fire, the fire extinguishing agent in the cavity will be able to extinguish the fire as a source of fire; To prevent the fire from burning to the cable core in the wear-resistant layer, and then affect the normal work of the cable core

Abstract

The invention belongs to the technical field of a cable and particularly relates to a high-strength impact-resistant flame-retardant insulation cable. The high-strength impact-resistant flame-retardant insulation cable includes a cable core and a cable base, wherein the cable core is externally wrapped in the cable base, an outer surface of the cable base is sleeved with a shape memory alloy layer, a surface of the shape memory alloy layer is sleeved with a glass fiber layer, an outer surface of the glass fiber layer is sleeved with an elastic base, the elastic base is internally provided with a chamber, the chamber is internally disposed with extinguishing chemical, and the fire extinguishing flame retardation effect is achieved for a fire through the extinguishing chemical in the chamber. After the shape memory alloy layer on the outer surface of the cable base expands, deformation wrapping for the cable base is generated, so strength and anti-impact performance of the cable base are improved, when internal thermal deformation of the cable base is prevented, softening of the cable base is generated, so strength and stiffness of the cable base are influenced, the glass fiber layer not only has the fire retardant effect, but also has the insulation effect.

Description

technical field [0001] The invention belongs to the technical field of cables, in particular to a high-strength impact-resistant and flame-retardant insulated cable. Background technique [0002] Cable refers to a wire product used to transmit electrical energy, electrical signals and realize electromagnetic energy conversion. According to the use, it can be roughly divided into power cables, control cables and communication cables. Various cables are suitable according to their uses. in different voltage ranges. [0003] Flame-retardant cable refers to the cable that the sample is burned under the specified test conditions. After the test fire source is removed, the spread of the flame is only within a limited range, and the residual flame or residual flame can extinguish itself within a limited time. [0004] There are also some technical solutions for flame-retardant and insulated cables in the prior art. For example, the application number 2017102477540 discloses a flam...
