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

Abstract

The invention proposes an anti-extruding stretch-proof power cable, and the cable comprises a first elastic tube, a second elastic tube, a plurality of first conductors, and a plurality of second conductors. The first elastic tube is disposed at an inner side of the second elastic tube, and the plurality of first conductors are disposed in the first elastic tube in a parallel manner. The second conductors have the elliptical sections, and the short axis of each second conductor is set in the radial direction of the cable. Two ends of each second conductor in each arc-shaped elastic part in the long-axis direction respectively abut against the arc-shaped elastic parts. Moreover, the plurality of second conductors abut against the outer wall of the first elastic tube. The first elastic tube and the second elastic tube are employed for respectively protecting the first conductors and the second conductors, and the interior of the first elastic tube and the interior of the second elastic tube are filled with gas. When the cable is extruded, the extruding force can be buffered through the elastic deformation of the first and second elastic tubes, thereby protecting the first and second conductors from being damaged by extruding, improving the application performance of the cable in a severe environment, and prolonging the service life of the cable.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to an extrusion-resistant and stretch-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 an extrusion-r...
