[0002] Many types of work are completed by industrialized equipment, and almost all equipment in industrial plants works continuously. The rhythm of continuous work not only requires adjustments for workers, but also for equipment, especially equipment electricity. For technicians in this field, the material selection of cables for industrial production equipment, especially the structural design of cables for industrial production equipment, is also a big challenge.

[0003] The main challenges faced by cables for industrial production equipment are: 1. Large power supply; 2. High power supply reliability; 3. Stable power supply load; 4. Good heat dissipation performance. The above four points are required for cables for industrial production equipment, and the above requirements are also technical problems to be solved by technicians in this field. Summary of the invention

[0004] In view of the problems existing in the prior art, the present invention discloses a cable for industrial production equipment. The present invention adopts multiple combination layers such as a phase change material layer and an insulating rope material layer, which can ensure that the cable has good heat dissipation performance while ensuring high power supply reliability and stable power supply load.

[0005] The present invention is achieved in that: A cable for industrial production equipment, characterized in that the cable comprises a plurality of groups of conductive inner cores, the plurality of groups of conductive inner cores are square phase change material layers, the phase change material layers fix the plurality of groups of conductive inner cores at the center of the cable; an insulating rope material layer is arranged outside the phase change material layer; The metal shielding layer is arranged outside the phase change material layer, and the shape of the metal shielding layer is circular. An aluminum foil tape layer is arranged outside the metal shielding layer, and the aluminum foil tape layer is square, and the metal shielding layer is tangent to the four sides of the aluminum foil tape layer; the inner sheath is arranged outside the aluminum foil tape layer, and a filler is arranged between the inner sheath and the aluminum foil tape layer; a polyethylene rubber protective layer is also arranged outside the inner sheath.

[0006] Furthermore, the conductive inner core is a whole of thin single wires twisted together; the conductive inner core is at least three groups, and when there are three groups, they are arranged in an isosceles triangle distribution, and when there are multiple groups, they are arranged in a centrally symmetrical or axially symmetrical distribution.

[0007] Furthermore, the phase change material layer is a paraffin / high-density polyethylene phase change material layer.

[0008] Furthermore, silicate sheets are arranged in the insulating rope material layer, and the silicate sheets are irregularly or regularly filled in the insulating rope material layer.

[0009] Furthermore, the filler is recycled rubber.

[0010] Furthermore, a cavity is provided in the polyethylene rubber protective layer, the cavity is provided closely to the inner wall of the polyethylene rubber protective layer, and a desiccant is provided in the cavity.

[0011] Furthermore, the insulating rope material layer is prepared from the following components by weight: polycaprolactam: 20-30 parts; aramid: 20-30 parts; copper alloy: 5-8 parts; aluminum alloy: 10-15 parts; tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer: 8-15 parts; antioxidant: 2-3 parts; flame retardant: 2-3 parts.

[0012] The beneficial effects of the present invention compared with the prior art are: The plurality of groups of conductive inner cores used in the present invention are centrally symmetrically or axially symmetrically distributed, which can ensure a large power supply for industrial equipment, and can also ensure power supply reliability and stable power supply load under a large supply.

[0013] The phase change material layer in the present invention can ensure stable power supply of the equipment under the heavy load of industrial production equipment. Under the dual protection of the metal shielding layer and the aluminum foil tape layer, the cable for industrial production equipment has better safety performance. Secondly, the setting of the inner and outer insulating rope material layers and the polyethylene rubber protective layer ensures that the cable for industrial production equipment has good heat dissipation performance.

[0014] In addition, the present invention limits the material of the insulating rope material layer and adopts a combination of conventional synthetic fiber (polycaprolactam) and high-strength synthetic fiber (aramid). The combination of the above materials makes the insulating rope material layer have good electrical and mechanical properties, giving the prepared product higher strength and wear resistance, and is suitable for insulating ropes that require higher mechanical strength. Tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer is incorporated into the insulating rope material layer, which has a higher temperature resistance level and excellent insulation performance, and is suitable for occasions that need to withstand high temperature and high voltage.
