Abstract

The invention discloses a 10 kV graphene composite shielding low-noise anti-interference overhead insulated cable, comprising a highly conductive composite aluminium conductor. The highly conductive composite aluminium conductor is composed of 37 highly conductive composite aluminium wires of a diameter of 2.54 mm by four-layer intertwisting in a "1+6+12 +18" structure mode; a graphene composite semiconductive shielding layer, a crosslinked polyethylene internal insulating layer and a modified weather-proof insulation external insulating layer are extruded outside the highly conductive composite aluminium conductor in common; and an outer surface of the modified weather-proof insulation external insulating layer is provided with a nanometer micro-spiral air guide groove by thermal printingand then a graphene composite glass fibre layer is arranged through extrusion weaving or sparse winding, and a layer of fluorocarbon paint is sprayed outside the graphene composite glass fibre layer.The 10 kV graphene composite shielding low-noise anti-interference overhead insulated cable has the advantages of high electric strength, high temperature resistance, high thermal stability, high anti-interference performance, high humidity resistance, good embrittlement resistance and weather aging resistance, and thus the service life of the cable is greatly prolonged, and the safety of the cable is greatly improved.

AI Technical Summary

Problems solved by technology

The shielding effect of the inner shielding layer is poor, and the insulation effect of the insulating layer is poor. When used in harsh weather environments such as the field, the open air, and strong sunlight, the cable itself consumes a lot of energy, has poor weather resistance, poor insulation performance, and large ultraviolet radiation damage.

There is no nano-micro-spiral air guide groove on the surface of the traditional overhead cable insulation layer, which cannot guide the wind direction, resulting in large noise, disturbing the residents and polluting the environment.

Traditional overhead cables have large consumables per unit length, high cost, low cost performance, backward technology, and waste of labor

[0003] At present, there is no professional manufacturer of this product in China; the traditional production technology is backward, the structural design is unreasonable, and the yield is low. In addition, the requirements for the safety, anti-electromagnetic interference and electromagnetic resistance of overhead cables are getting higher and higher in recent years, resulting in Due to the existing technology, many manufacturers cannot design and produce intelligent environmental protection medium voltage power cable products that meet the technical requirements

And the production process has the following problems: 1, the processing capacity is large, and the production cost is high

2. It is not conducive to laying and management, and the risk factor is large

3. Difficult assembly of finished products and long production cycle

4. The structure is unreasonable; 5. It cannot effectively reduce the impact grounding impedance of the grounding body, and cannot reduce the counter-attack overvoltage; 6. It is not suitable for construction difficulties such as acidic soil, alkaline soil, swamp, hot and humid areas, beaches, and mountains and hills. used where the rate is high
