Cable with multi-layer structure

Abstract

The invention provides a cable with a multi-layer structure. The cable comprises a conductor (1), a wrapping layer (2), a shielding layer (3), an armoring layer (4), a flame-retardant layer (5), a waterproof layer (6) and an isolation layer (7), wherein the wrapping layer (2) is arranged on the exterior of the conductor in an extrusion manner; the shielding layer (3) is arranged on the exterior of the wrapping layer (2) in an extrusion manner; the armoring layer (4) is arranged on the exterior of the shielding layer (3) in an extrusion manner; the flame-retardant layer (5) is arranged on the exterior of the armoring layer (4) in an extrusion manner; the isolation layer (7) is arranged on the exterior of the flame-retardant layer (5) in an extrusion manner; the waterproof layer (6) is arranged on the exterior of the isolation layer (7) in an extrusion manner; the flame-retardant layer (5) is 2-3mm in thickness; and the thickness of the armoring layer (4) is the same as that of the flame-retardant layer. The cable with the multi-layer structure has the advantages of simple and reasonable structure, shielding property, tensile property, flame retardancy, waterproof property and the like.

Description

technical field [0001] The invention relates to a cable with a multilayer structure, which belongs to the technical field of power cables. Background technique [0002] Cables are used in all fields of life and are the basis of modern life. However, in some special environments, the requirements for cables are higher, and special requirements such as tensile resistance, waterproof, and flame retardancy are required. Traditional cables cannot meet the above requirements. [0003] Therefore, it is necessary to propose a new technical solution to solve the above problems. Contents of the invention [0004] In view of the above problems, the object of the present invention is to provide a cable with a multi-layer structure. [0005] The present invention is a cable with a multi-layer structure, comprising a conductor, a wrapping layer, a shielding layer, an armor layer, a flame-retardant layer, a waterproof layer, and an isolation layer, the conductor is extruded around the w...
