Special power cable for rail transit

Abstract

The invention relates to the technical field of a special power cable and discloses a special power cable for rail transit. The special power cable comprises an anticorrosion layer. The inner side ofthe anticorrosion layer is fixedly equipped with symmetrically-distributed upper and lower support plates. The opposite sides of the two support plates are respectively and fixedly equipped with a first support rod. The back side of the first support rod is fixedly equipped with a second support rod. The inner portion of the anticorrosion layer is fixedly equipped with insulation rings arranged atthe left and right sides of the first support rod and the second support rod. The inner side of each insulation ring is fixedly provided with an armor layer. The top portion and the bottom portion ofthe armor layer are fixedly equipped with steel wires. The inner side of the armor layer is fixedly provided with a shielding layer. The inner side of the shielding layer is fixedly provided with connecting rods. The ends, away from the shielding layer, of the connecting rods are fixedly provided with a connecting ring. The special power cable for rail transit has the advantage of having high resistance to compression and deformation, and solves the problem that the cable's compression resistance and deformation resistance are far from enough when the cable is applied in rail transit.

Description

technical field [0001] The invention relates to the technical field of special cables, in particular to a special power cable for rail transit. Background technique [0002] Special cables are cables with special purposes that can be used in specific occasions, such as high temperature resistance, acid and alkali resistance, termite resistance, and wires and cables used in ships, aircraft, nuclear power plants, etc. In terms of classification, it is different from Electricity, control, computer cables and other categories do not belong to the same classification method, that is, special cables are also included in the above-listed cables, and generally special cables need to formulate internal control standards for enterprises. [0003] Chinese patent CN200810041136.1 discloses a multi-functional composite elevator accompanying cable. In the present invention, cables with multiple functions are installed in the existing elevator accompanying cable, which greatly reduces the ...
