Problems solved by technology

At present, when the cable is used, there are many harsh environments, and the cable is prone to damage in the harsh environment, so the cable in the harsh environment needs to be maintained frequently, and the cost is extremely high, especially in the high temperature environment, the cable Excellent insulation, fire resistance, and high temperature resistance are the most basic conditions for cables, and fire is also a common disaster at present, and in the process of disasters, power protection settings rely on cables to transmit signals and electric energy to a large extent. Let it work, therefore, the fire performance of the cable is very important for today's production and life
[0003] Existing flame-retardant cables have relatively simple flame-retardant methods, and the flame-retardant methods are usually directly using flame-retardant rubber sleeves, or applying flame-retardant coatings, or spraying flame-retardant powder on the surface of the rubber layer. The method of forming a flame-retardant layer, but the existing coating method and spraying method do not have suitable proprietary equipment. Traditional spraying, dipping and spraying guns and other equipment or methods have defects, which will affect the molding quality. Therefore, it needs to be improved; in addition, the existing flame-retardant cables must contain multiple wires, and the adjacent wires are mainly separated by fillers such as wire ropes, but the stability is poor, the extrusion resistance is insufficient, and there is no Has good thermal conductivity

Abstract

The invention discloses a fireproof and pressure-resistant rubber special-shaped cable and a preparation process thereof. The fireproof and pressure-resistant rubber special-shaped cable has good fireproof and flame-retardant performance and extrusion-resistant performance, and the forming quality is high in the preparation process. The fireproof and pressure-resistant rubber special-shaped cable is characterized by comprising an outer sheath and a plurality of wires arranged in the outer sheath, wherein each wire comprises a wire core and an insulating layer wrapping the outer wall of the wire core, a flexible framework of a flat structure is arranged in the outer sheath, the wires are horizontally arranged at equal intervals and embedded in the flexible framework, a flame-retardant sleeve is further arranged between the outer sheath and the flexible framework, and a flame-retardant filling layer is further arranged between the flame-retardant sleeve and the outer sheath. The invention is applicable to the technical field of cables.

Description

technical field [0001] The invention belongs to the technical field of cables, in particular to a fireproof and pressure-resistant rubber special-shaped cable and a preparation process thereof. Background technique [0002] Cables are generally used to transmit electrical energy, electrical signals, etc., and cables have become an indispensable part of information transmission in today's life. At present, when the cable is used, there are many harsh environments, and the cable is prone to damage in the harsh environment, so the cable in the harsh environment needs to be maintained frequently, and the cost is extremely high, especially in the high temperature environment, the cable Excellent insulation, fire resistance, and high temperature resistance are the most basic conditions for cables, and fire is also a common disaster at present, and in the process of disasters, power protection settings rely on cables to transmit signals and electric energy to a large extent. Let i...
