Speed sensor connecting cable

Abstract

The invention relates to the technical field of power cables, and discloses a speed sensor connecting cable. The speed sensor connecting cable comprises a cable, wherein a plurality of bundles of conductors are arranged in the cable, the outer side of the conductor is coated with a layer of natural butylbenzene insulation, the plurality of bundles of conductors are embedded in an inner sheath, theinner sheath is internally provided with a filler, the outer side of the inner sheath is wrapped with an armor layer, the outer side of the armor layer is wrapped with an outer sheath, the inner sheath is internally provided with a plurality of strip-shaped cavities, the outer sheath is internally provided with a plurality of arc-shaped cavities, and the arc-shaped cavities are distributed on theouter side of the armor layer. According to the speed sensor connecting cable, the plurality of arc-shaped cavities are formed in the outer sheath, so that the mass of the overall production raw materials of the outer sheath is reduced, and the environment is protected in the production link. In addition, the arc-shaped cavities are filled with the flame-retardant gas, the arc-shaped cavities inthe outer sheath have certain elasticity, and collapse of the arc-shaped cavities when the outer wall of the outer sheath is pressed is avoided.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a speed sensor connection cable. Background technique [0002] Connecting cables usually use the purity of the copper content of the wire to indicate the quality of the wire. For example, 6N means that the copper content of the wire has reached 99.99997%. Most of the good performance is composed of multi-core wires, and there are also single or several thick copper wires. [0003] Existing connecting cables generally include a series of structures such as conductor, natural styrene-butadiene insulation, filling, inner sheath, armor layer and outer sheath. The outer sheath is generally made of rubber and is generally a solid structure. It consumes more rubber raw materials, which makes the cost of the cable higher, and is not conducive to environmental protection, and generally the outer sheath is located on the outermost side of the cable but does not have certain flame ret...

[0003] Existing connecting cables generally include a series of structures such as conductor, natural styrene-butadiene insulation, filling, inner sheath, armor layer and outer sheath. The outer sheath is generally made of rubber and is generally a solid structure. It consumes more rubber raw materials, which makes the cost of the cable higher, and is not conducive to environmental protection, and generally the outer sheath is located on the outermost side of the cable but does not have certain flame retardancy. Therefore, we propose a speed sensor connection cable to solve the problem. above question
