Description

Technical Field

[0001] The utility model belongs to the technical field of cables, and in particular relates to a high-temperature resistant and wear-resistant cable. Background Art

[0002] Cable is a general term for items such as optical cables and electrical cables. It is an indispensable and important equipment in modern society. Cable is an electronic transmission medium composed of conductors, insulation layers, sheath layers and other parts, and is mainly used to transmit electrical signals, electricity or data. They are widely used in many fields such as communications, construction, industry, energy, transportation, and medical care. They are important tools for multiple functions such as control installation, connecting equipment, and transmitting electricity. The structure of cables usually includes conductors, insulation layers and sheath layers. Conductors are elements that conduct current and are usually made of conductive materials such as copper or aluminum. The insulation layer is wrapped around the outside of the conductor to prevent current leakage and short circuits, while protecting the conductor from the external environment. The sheath layer is wrapped around the outside of the insulation layer to provide additional mechanical and environmental protection.

This wear-resistant and high-temperature resistant cable is provided with a first functional layer comprising a mica tape layer and a phosphate lead powder coating layer, wherein the mica tape layer has excellent high-temperature resistance and flame resistance, the phosphate lead powder coating layer has high-temperature resistance, high strength, and crack resistance, and also has good oil resistance, acid and alkali resistance.

Utility Model Content

[0005] In response to the problems mentioned in the background technology, the purpose of the present utility model is to provide a high-temperature resistant and wear-resistant cable to solve the problem that the material inside the cable will expand thermally in a high-temperature environment; and when the temperature drops, it will shrink, resulting in deformation and cracking of the cable structure. In addition, the heat dissipation performance inside the cable is poor, which can easily lead to excessively high internal temperature of the cable, affecting the overall performance and life of the cable.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A high-temperature and wear-resistant cable comprises a cable core, a reinforcing core ring and a cable protective cover, the outer wall of the reinforcing core ring is symmetrically fixedly connected to a support plate through an annular array, the end of the support plate away from the reinforcing core ring is fixedly connected to the inner wall of the cable protective cover, the cable core and the support plate are staggered, one end of the support plate is provided with a mounting groove, a thermally conductive strip is fixedly connected inside the mounting groove, a silicone filler is filled between the cable protective cover and the reinforcing core ring, the cable core is located in the silicone filler, a cross reinforcing plate is fixedly connected inside the reinforcing core ring, and a silicone filler is filled between the cross reinforcing plate and the reinforcing core ring. The thermally conductive strips arranged on the support plate can quickly conduct heat generated inside the cable, thereby reducing the working temperature of the cable, and at the same time can help evenly distribute the heat inside the cable, reduce local overheating, and avoid performance degradation or damage caused by uneven temperature distribution. The silicone filler can maintain the stability of its physical and chemical properties in a higher temperature environment, thereby enhancing the overall high-temperature resistance of the cable, and at the same time can more effectively isolate the conductor to prevent current leakage and short circuit.

The waterproof layer can prevent water and moisture from invading the interior of the cable, prevent current leakage or short circuit, and the thermal insulation layer can maintain stability in a high temperature environment to prevent the cable from being damaged by high temperature.

[0009] As an optimal technical solution, the outer protective layer includes a thermal insulation layer, a waterproof layer and a wear-resistant layer. The waterproof layer is fixedly connected to the outside of the thermal insulation layer, and the wear-resistant layer is fixedly connected to the outside of the waterproof layer. The thermal insulation layer is made of ceramic fiber, the waterproof layer is made of polyethylene, and the wear-resistant layer is made of polyurethane.

[0010] As an optimal technical solution, the outer wall of the wear-resistant layer is symmetrically fixed with flame-retardant convex hulls through a ring array. The interior of the flame-retardant convex hulls is filled with mineral fillers, which can provide additional fire protection, slow down the spread of flames, and isolate external heat to a certain extent to prevent the cable from being damaged by external high temperature.

[0011] As a preferred technical solution, heat dissipation holes are symmetrically opened on the outer wall of the wear-resistant layer. The heat dissipation holes are evenly distributed on the wear-resistant layer. The heat dissipation holes are conducive to the dissipation of heat inside the cable.

[0012] As an optimal technical solution, the armor layer includes a metal braided layer, which is made of aluminum alloy. The metal braided layer in the armor layer can effectively protect the cable from external physical damage, such as mechanical impact, cutting, puncture, pulling, etc.

[0013] As a preferred technical solution, the inner sheath includes an inner lining layer and an insulating layer. The inner lining layer is fixedly connected to the outside of the insulating layer. The insulating layer is made of cross-linked polyethylene and the inner lining layer is made of polyvinyl chloride. The inner lining layer in the inner sheath can resist the invasion of external corrosive media, significantly enhance the durability of the cable, and reduce cable damage and failures caused by external environmental factors. The insulating layer can provide electrical isolation, prevent electrical contact between cables, and ensure the safe operation of the cables.

[0014] In summary, the present invention has the following beneficial effects:

[0015] First, in the present invention, the heat generated inside the cable can be quickly conducted away by the heat conductive strips provided on the support plate, thereby reducing the operating temperature of the cable. At the same time, the heat inside the cable can be evenly distributed, thereby reducing local overheating and avoiding performance degradation or damage caused by uneven temperature distribution.

[0030] Principle and advantages of use: The heat-conducting strips 8 provided on the support plate can quickly conduct heat generated inside the cable, thereby reducing the operating temperature of the cable. At the same time, they can help evenly distribute heat inside the cable, reduce local overheating, and avoid performance degradation or damage caused by uneven temperature distribution. The heat-conducting strips 8 improve heat dissipation efficiency and reduce the operating temperature of the cable, thereby slowing down the aging of the material and extending the service life of the cable. In addition, the silicone filler 9 can maintain the stability of its physical and chemical properties in a high temperature environment, thereby enhancing the overall high-temperature resistance of the cable.
