Problems solved by technology

[0005] The invention provides a flexible insulated fireproof cable with a metal sheath, one purpose of which is to provide the cable with the ability to withstand external impact and extrusion, so as to avoid the burning of the cable during use, and to solve the problem of the cable being subjected to external impact and pressure. When extruded, it is easy to break the cable, so that the cable is damaged and burned; another purpose is to solve the problem that the cable is prone to damage due to the limited compressive capacity of the cable when the cable is erected for too long In order to achieve the effect that the cable core in the cable can be prevented from being damaged when the length of the cable is too long

Abstract

The invention discloses a flexible insulating fireproof cable provided with a metal sheath, and relates to the technical field of cables, the flexible insulating fireproof cable comprises three cable cores which are mutually twisted, a buffer filler is arranged among the gaps of the cable cores, the outer wall of the buffer filler is provided with a thermal insulation layer, the outer wall of the thermal insulation layer is provided with a shielding layer, and the shielding layer is provided with a metal sheath. A protective layer is arranged on the outer wall of the shielding layer, a flame-retardant layer is arranged on the outer wall of the protective layer, and a plastic insulating layer is arranged on the outer wall of the flame-retardant layer. According to the invention, through the cooperation of the flame-retardant layer, the flame-retardant outer layer, the flame-retardant inner layer, the flame-retardant connecting layer, the anti-deformation filler and the metal sheath, the surface of the metal sheath can be protected through the anti-deformation filler through the cooperation between the anti-deformation filler and the metal sheath; the flame-retardant outer layer and the flame-retardant inner layer can buffer the impact force between the metal sheath and a hard object, so that the cable is prevented from being damaged, and the cable can be prevented from burning through the cooperation between the flame-retardant outer layer and the flame-retardant inner layer.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a flexible insulated fireproof cable provided with a metal sheath. Background technique [0002] As one of the largest supporting industries in the national economy, wire and cable is the foundation of various industries. Its products are widely used in electric power, construction, civil, communication, shipbuilding, military industry, aviation, petrochemical and other fields. Wires and cables are closely related to the development of the national economy. They are known as the "blood vessels" and "nerves" of the national economy. Basic products necessary for future electrification and information society. Calculated by the scale of output value, the wire and cable industry is second only to the automobile manufacturing and parts and accessories manufacturing industry in the subdivision industries of my country's machinery industry; it is the largest among more than 20 subdivisi...
