Description

Technical Field

[0001] The utility model belongs to the technical field of cables, and particularly relates to a cable with an antifreeze structure. Background Art

[0002] Cables are usually rope-like cables made of several or several groups of wires twisted together. Each group of wires is insulated from each other and twisted around a central core. The entire cable is covered with a highly insulating covering. They are often installed in the air or underground or underwater for telecommunications or power transmission. The wire and cable industry is the second largest industry in China after the automotive industry.

[0003] At present, cables are widely used, and the performance requirements for them in different usage scenarios vary greatly. For example, for cables installed outdoors, low temperature environments are not conducive to the service life of the cables.

[0004] Therefore, in view of the shortcomings of the above-mentioned scheme in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, the present utility model was created, and a cable with an anti-freeze structure is provided to solve the above-mentioned problems. Utility Model Content

[0005] The utility model provides a cable with an antifreeze structure, which solves the problems in the prior art.

[0006] The technical solution of the utility model is implemented as follows: a cable with an antifreeze structure comprises: a plurality of conductors, an insulating layer is arranged outside the plurality of conductors, a plurality of fillers are arranged outside the insulating layer, two conductive busbars are matched inside the fillers, and graphite particles are arranged between the two conductive busbars;

[0007] An inner sheath is arranged outside the filler, a heat preservation layer is arranged outside the inner sheath, a waterproof layer is arranged outside the heat preservation layer, a steel wire armor layer is arranged outside the waterproof layer, and an outer sheath is arranged outside the steel wire armor layer.

[0008] By adopting the above scheme, the two conductive busbars have formed a loop in the inner sheath. Under the action of thermal expansion and contraction, the cable shrinks when the temperature drops. At this time, the graphite particles and the conductive busbars contact each other to form a circuit. The graphite particles are conductive, and the flow of current will be accompanied by heat, thereby improving the cable's anti-freeze ability.

[0009] As a preferred embodiment of the cable with an antifreeze structure, the filler is located between two conductors, a slot is provided in the middle of the filler, and the conductive busbar is slidably fitted in the slot.

[0010] By adopting the above solution, the slot is used to enhance the position stability of the conductive busbar.

[0011] As a preferred embodiment of the cable with an antifreeze structure, the inner sheath and the outer sheath are both made of chloroprene rubber.

[0012] As a preferred embodiment of the cable with an antifreeze structure, the thermal insulation layer is a glass wool.

[0013] As a preferred embodiment of the cable with an antifreeze structure, the waterproof layer is a waterproof cloth.

[0014] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: the utility model proposes a cable with an antifreeze structure with good antifreeze ability. Under the effect of thermal expansion and contraction, the cable shrinks when the temperature drops. At this time, the graphite particles contact with the conductive busbar to form a circuit. Since the graphite particles are conductive, the flow of current will be accompanied by heat, thereby improving the cable's antifreeze ability, reducing freezing and extending its service life.
