Super-hydrophobic ice-resistant coating for special cable

Abstract

The invention discloses a super-hydrophobic ice-resistant coating for a special cable, and belongs to the technical field of power transmission. The super-hydrophobic ice-resistant coating for the special cable comprises a cable core, the outer surface of the cable core is sleeved with an insulating layer, the outer surface of the insulating layer is wrapped with a composite protection layer, and buffer supporting rods are arranged on the outer surface of the composite protection layer in a surrounding array mode. The buffer supporting rods are of a corrugated structure, reinforcing rings are fixedly welded to the concave centers of the buffer supporting rods and arrayed in the extending direction of the buffer supporting rods at equal intervals, a shell is connected between the outer surfaces of the buffer supporting rods in a sleeved mode, the shell is corrugated, and drainage bags are arranged on the shell in a circulating and protruding mode. A drainage groove is formed between every two adjacent drainage bags in a sunken mode, and the drainage bags and the drainage grooves are the same in radian. A super-strong hydrophobic layer can be formed on the surface of the cable, liquid accumulation is reduced through the icebreaking structure, the icing thickness is further reduced, a buffer space is provided, and the influence of icing on the structure of the cable is reduced.

Description

technical field [0001] The invention relates to the technical field of power transmission, in particular to a superhydrophobic anti-icing coating for special cables. Background technique [0002] The high-voltage overhead transmission line will generate a certain amount of heat under the condition of power transmission. In winter, due to the low temperature, the heat generated by the high-voltage transmission line under the condition of power transmission will be immediately absorbed by the surrounding low temperature. Therefore, under weather conditions such as rain and snow, As a result, the attached snowflakes change from a solid form to a liquid form. If the liquid accumulates on the surface of the cable, it will eventually lead to icing on the transmission line. Once the icing thickness of the transmission line exceeds the allowable icing thickness of the design, it is prone to failure, and due to the long power supply distance of the transmission line and the large tra...

Problems solved by technology

Once the icing thickness of the transmission line exceeds the allowable icing thickness of the design, it is prone to failure, and due to the long power supply distance of the transmission line and the large transmission capacity, once a failure occurs, it will cause a total amount of damage to downstream power consumers and individuals. huge economic loss
