Embodiment Construction

[0012] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of an extrusion-resistant and tensile-resistant power cable proposed by the present invention.

[0013] refer to figure 1 , an anti-extrusion and stretch-resistant power cable proposed by the present invention, comprising a cable core, a wrapping layer 3, an elastic anti-extrusion layer 4, a shielding layer 5, and a sheath layer 6;

[0014] The cable core is composed of an elastic support frame 1 and a plurality of conductors 2. The conductor 2 includes a conductor 21 located in the middle, and the conductor 21 is covered with an insulating layer 22. The support plates 12 are integrated, and the support plates 12 are arranged radially along the cylinder 11. One end of all the support plates 12 is located in the cylinder 11 and meets at the central axis of the cylinder 11, and the other end passes through the side wall of the cylinder 11. The outer side of the cylinder 11 leans against the wrappi...

Abstract

The invention discloses an extruding-resistant and stretch-proof power cable which comprises a cable core, a lapped covering layer, an elastic extruding-resistant layer, a shielding layer and a sheath layer. The cable core is formed by an elastic supporting frame and a plurality of wires. The elastic supporting frame is integrally formed by a cylinder and a plurality of supporting plates arranged in the radial direction of the cylinder. One end of each supporting plate is located in the cylinder, and the other end of each supporting plate penetrates through the side wall of the cylinder and abuts against the lapped covering layer at the position of the outer side of the cylinder. A plurality of steel wires are arranged in the elastic supporting frame in the longitudinal direction. Each wire comprises a conductor arranged in the middle and an insulating layer covering the conductor. The wires are longitudinally arranged between any two adjacent supporting plates and located on the outer side of the cylinder. The cable core is wrapped with the lapped covering layer wrapped with the elastic extruding-resistant layer. A plurality of longitudinal through holes are formed in the elastic extruding-resistant layer wrapped with the shielding layer. The shielding layer is wrapped with the sheath layer. The extruding-resistant stretch-proof power cable is excellent in extruding-resistant and stretch-proof performance.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an extrusion-resistant and stretch-resistant power cable. Background technique [0002] In metallurgy, electric power, petrochemical and other working environments that have special requirements for cables such as mobile anti-corrosion, cables are more likely to be squeezed and stretched by the outside after installation, especially in the process of anti-extrusion, the wires in the cable core are easily deformed or even The core is easy to break, and the smooth transmission of power and communication cannot be guaranteed, causing huge economic losses. Therefore, how to manufacture a power cable that is resistant to extrusion, stretching and stable in structure has become a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the present invention p...
