Anti-breakage tensile cable

Abstract

The invention discloses an anti-breakage tensile cable. The anti-breakage tensile cable comprises a cable body, wherein the cable body comprises conductors, an insulation layer, a shielding layer and an outer sheath, wherein a plurality of conductors are arranged in the cable body; the cross sections of the conductors adopt circular structures; an optical unit is arranged at the center of the cable body; the insulation layer tightly wraps the outside of the conductors; an insulation tape layer is arranged in a gap part between the insulation layer and the conductors; the shielding layer tightly wraps the outside of the insulation layer; a ripple stainless steel layer tightly wraps the outside of the shielding layer; the ripple stainless steel layer is wrapped with a fireproof mica tape and the outer sheath in sequence from inside to outside; a glue coating layer is arranged between the outer sheath and the fireproof mica tape. The cable has the advantages of reasonable structural design, breakage resistance and long service life.

Description

technical field [0001] The invention relates to the field of cables, in particular to a fracture-resistant and stretch-resistant cable. Background technique [0002] At present, with the development of science and technology, industry and other fields are also making rapid progress, which brings about an increase in the amount of cables. Cables are usually similar ropes with several or several groups of wires twisted at least two in each group. Each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating covering layer. There are many types of cables, which can be used in many fields and different environments. They are different, so there are different requirements for cables, but the existing cables cannot adapt to some areas with harsh environments due to their unreasonable structural design. After long-term use, the sheath often breaks, resulting in The internal structure of the cable ...

[0002] At present, with the development of science and technology, industry and other fields are also making rapid progress, which brings about an increase in the amount of cables. Cables are usually similar ropes with several or several groups of wires twisted at least two in each group.

There are many types of cables, which can be used in many fields and different environments. They are different, so there are different requirements for cables, but the existing cables cannot adapt to some areas with harsh environments due to their unreasonable structural design. After long-term use, the sheath often breaks, resulting in The internal structure of the cable was damaged, which brought a lot of trouble to the later work
