Description

Technical Field

[0001] The utility model relates to the technical field of multi-core special cables, in particular to a corrosion-resistant multi-core special cable. Background Art

[0002] Special cables are cables with special purposes and can be used in specific occasions, such as cables that are resistant to high temperatures, acids and alkalis, and termites, as well as cables used in ships, airplanes, nuclear power plants, etc. In terms of classification, they do not belong to the same classification method as power, control, and computer cables. That is, the cables listed above also include special cables. Generally, special cables require the formulation of enterprise internal control standards. The use environment of special cables is different from that of general wires and cables. The use environment of special cables is more complicated.

[0003] When the existing cables are subjected to external pressure, the cable sheath is easily deformed, thereby changing the position of the internal conductor, and there is a great possibility that the conductor will be deformed and damaged.

[0004] For example, a special multi-core composite wire and cable disclosed in Chinese patent CN211957181U separates the supporting core and the single core by connecting the wire-adjusting reel. The supporting plate can increase the strength of the connecting wire-adjusting reel so that when the entire cable is subjected to force, it is supported by the supporting plate, so that the entire connecting wire-adjusting reel will not be easily deformed, thereby protecting the supporting core and the single core, and the single core and the supporting core can be effectively protected by the insulating wrapping layer.

[0005] The existing special cables do not have the function of heat preservation when working, which makes the power loss degree large and causes the waste of power.

[0006] For this reason, we urgently need to provide a kind of corrosion-resistant multi-core special cable with heat preservation function. Utility Model Content

[0007] The utility model aims to provide a corrosion-resistant multi-core special cable to solve the problem that the existing special cables mentioned in the above background technology do not have the function of heat preservation during operation, resulting in a large degree of power loss and a waste of power.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a corrosion-resistant multi-core special cable, comprising a conductor, the outer end of the conductor is connected to a protection mechanism, the protection mechanism comprises a thermal insulation unit and a protection unit, the thermal insulation unit is arranged at the outer end of the conductor, and the protection unit is arranged at the outer end of the thermal insulation unit.

[0009] The heat preservation unit comprises a heat preservation layer, an insulating layer and a supporting layer. The heat preservation layer is sleeved on the outer end of the conductor, the insulating layer is sleeved on the outer end of the heat preservation layer, and the supporting layer is sleeved on the outer end of the insulating layer.

[0010] A further improvement is that the material of the thermal insulation layer is thermal insulation cotton, so that when the temperature of the outer end of the cable drops, the conductor can be kept warm under the protection of the thermal insulation layer.

[0011] A further improvement is that the material of the insulating layer is PVC polyethylene, so that the conductor is insulated from the outer end, ensuring the smooth transmission of electrical energy.

[0012] A further improvement is that the support layer is a steel wire mesh structure, which makes the cable tensile resistant, improves the performance of the special cable, and prolongs the service life of the special cable.

[0013] A further improvement is that the protection unit includes a buffer layer, a waterproof layer and a protective layer, the buffer layer is sleeved on the outer end of the support layer, the waterproof layer is sleeved on the outer end of the buffer layer, and the protective layer is sleeved on the outer end of the waterproof layer.

[0014] A further improvement is that the material of the buffer layer is rubber. The buffer layer made of elastic rubber can protect the internal conductor when the cable is impacted, thereby preventing the conductor from being damaged due to the impact.

[0015] A further improvement is that the waterproof layer is made of waterproof rubber cloth, which can prevent rainwater from entering the cable and damaging the conductor when the protective layer at the outer end is damaged.

[0016] A further improvement is that the protective layer is made of polyvinyl chloride, so that by putting the protective layer made of polyvinyl chloride on the outermost end of the cable, it can play an anti-corrosion role on the entire cable, and at the same time, when used in the soil, it can prevent being bitten by insects such as ants.

[0017] In summary, the present application discloses a corrosion-resistant multi-core special cable.

[0018] This technical solution can keep the conductor warm when the temperature of the outer end of the cable drops, under the protection of the insulation layer, and can prevent the waste of electric energy.

[0019] Furthermore, by covering the outermost end of the cable with a protective layer made of polyvinyl chloride, the entire cable can be protected from corrosion, and when used in the soil, it can be prevented from being bitten by insects such as ants. BRIEF DESCRIPTION OF THE DRAWINGS
