Problems solved by technology

[0002] In the field of automatic production and processing, the power cable is often squeezed due to the action of the processing parts, and the power cable is often broken; when the power cable is squeezed, it will inevitably squeeze the conductor core wire, thereby Impact on power transmission quality
In addition, the current-carrying capacity of power cables is usually related to the cross-sectional area of ​​the conductor core. When the current increases, the temperature of the conductor will increase. Change, so that the insulation reliability of the insulation layer is greatly reduced, affecting the service life of the power cable

Embodiment Construction

[0020] refer to figure 1 , the present invention proposes a twist-resistant and anti-deformation power cable, including a central conductor 1, a plurality of outer conductors 2 and an elastic protection tube 3, wherein:

[0021] The elastic protection tube 3 is made of polyurethane material, the center wire 1 and the four outer wires 2 are all arranged in the elastic protection tube 3, and the gap between the center wire 1, the four outer wires 2 and the elastic protection tube 3 is filled with Refractory materials9.

[0022] The central conductor 1 has a circular cross-section, the outer conductor 2 has an elliptical cross-section, and the central conductor 1 includes a central conductor 11, a central insulating layer 12 wrapped outside the central conductor 11, and a central shielding layer 13 wrapped outside the central insulating layer 12. The shielding layer 13 is formed by loosely winding copper wires, and the outer shielding layer 23 is formed by overlapping and wrappi...

Abstract

The invention provides a twisting-resisting and anti-deformation power cable. The power cable comprises a center conductor, multiple outer conductors and an elastic protective tube, wherein multiple outer conductors are longitudinally arranged at the outside of the center conductor in parallel, and two ends of any outer conductor are respectively contacted with the center conductor and the elastic protective tube; an inner sheath, a total shielding layer and an outer sheath are orderly covered out of the elastic protective tube; the elastic bracket with the number same as the number of the outer conductor is arranged between the elastic protective tube and the inner sheath, and one elastic bracket is arranged between any two adjacent outer conductors; one end of the elastic bracket is connected with the inner wall of the inner sheath, and the other end of the elastic bracket is connected with the elastic protective tube and the elastic protective tube is pressed between any two adjacent outer conductors; and the elastic buffer material is filled in a gap between the elastic protective tube and the inner sheath. The cable provided by the invention can buffer the extrusion force through the elastic deformation of the elastic protective tube, the elastic brackets and the elastic buffer material in the extrusion, thereby preventing the center conductor and the outer conductors from being damaged by extrusion, and the use performance of the cable is improved.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a twist-resistant and deformation-resistant power cable. Background technique [0002] In the field of automatic production and processing, the power cable is often squeezed due to the action of the processing parts, and the power cable is often broken; when the power cable is squeezed, it will inevitably squeeze the conductor core wire, thereby affect the quality of power transmission. In addition, the current-carrying capacity of power cables is usually related to the cross-sectional area of ​​the conductor core. When the current increases, the temperature of the conductor will increase. Change, so that the insulation reliability of the insulating layer is greatly reduced, affecting the service life of the power cable. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a twist-resista...
