Problems solved by technology
[0002] Cables are used to transmit directional motion charges, which are widely used in power systems and information transmission systems. In the process of charge transmission, due to the certain resistance of the wires in the cables, when the current flows, under the action of the magnetic field and force field The cable core will be squeezed, which will cause wear to the rubber layer and insulation layer of the cable inner cavity. After a period of time, the cable may no longer be a sealed structure. Once the cable core comes into contact with air, it will cause fire, and then Blow out the entire line, causing an accident

The invention discloses a pressure-resistant cable. The pressure-resistant cable comprises an outer cover, a rubber layer, cable cores and a filler, wherein an anaerobic layer is arranged on the inner side of the outer cover; a steel tape armoring layer is arranged on the inner side of the anaerobic layer; the cable cores and the filler are arranged on the inner side of the steel tape armoring layer respectively; each cable core consists of an insulating layer, a shielding layer and a cable conductor, the inner side of each insulating layer is connected with the corresponding shielding layer, and the corresponding cable conductor is arranged in the inner cavity of each shielding layer; a fixed plate is arranged on one side of each cable core; an upper supporting plate is arranged at the bottom of each cable core; and the bottom of each upper supporting plate is connected with a lower supporting plate through a cushion. The pressure-resistant cable is provided with the rubber layer, so that the cable cores and the fixed plates can be fixed; the pressure-resistant cable is provided with the filler, so that the cable cores are prevented from moving at random when being subjected to a force field; the two fixed plates are arranged between the adjacent cable cores, so that the cable cores are cushioned on the cushion under the supporting of the supporting plates when being extruded by force, and the rubber layer and the insulating layer are prevented from causing abrasion.
Description
technical field [0001] The invention relates to the technical field of power equipment, in particular to a pressure-resistant cable. Background technique [0002] Cables are used to transmit directional motion charges, which are widely used in power systems and information transmission systems. In the process of charge transmission, due to the certain resistance of the wires in the cables, when the current flows, under the action of the magnetic field and force field The cable core will be squeezed, which will cause wear to the rubber layer and insulation layer of the cable inner cavity. After a period of time, the cable may no longer be a sealed structure. Once the cable core comes into contact with air, it will cause fire, and then Blow the whole line, causing the accident. Contents of the invention [0003] The purpose of the present invention is to provide a pressure-resistant cable to solve the problems raised in the background art above. [0004] In order to achiev...
