Reinforced composite shielding instrument control cable

Abstract

The invention discloses a reinforced composite shielding instrument control cable. The cable comprises a cable core, an insulating layer, a copper strip shielding layer and a shielding sheath layer, and the insulating layer, the copper strip shielding layer and the shielding sheath layer sequentially wrap the outer side of the cable core from inside to outside. The cable core comprises a belting layer, main wire cores and control wire cores which are extruded in the belting layer, and a reinforcing layer which coats the outer side of the belting layer; and the reinforcing layer comprises semi-ring single bodies I arranged on the outer side of the belting layer at equal intervals in the length direction of the belting layer and semi-ring single bodies II arranged on the outer side of the belting layer at equal intervals in the length direction of the belting layer. When the cable is extruded, the elastic layer firstly plays a preliminary buffering role, then pressure is applied to the reinforcing layer, so that the first semi-ring monomer and the second semi-ring monomer get close to each other, and at the moment, the first inclined plane and the second inclined plane between the first semi-ring monomer and the second semi-ring monomer are matched, so the first semi-ring monomer and the second semi-ring monomer move upwards towards the axial direction of the cable, so that the pressure is decomposed to the length direction of the cable, and the compression resistance of the cable is improved.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a reinforced composite shielding instrument control cable. Background technique [0002] At present, the cables used in the fields of iron and steel plants, power plants, ships and aviation have high quality requirements in all aspects of the cables, because safety in these fields is very important, and generally no safety hazards are allowed to exist. There are many instruments in these fields, and it is extremely easy to squeeze the cable during operation, resulting in the breakage of the cable core, which has a greater safety hazard. [0003] In view of this, a reinforced composite shielded instrument control cable is designed to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a reinforced composite shielded instrument control cable to solve the problems raised in the background art above. [0005] In order to a...
