Abstract

The invention discloses an anti-icing cable. The cable comprises a core, a shielding layer and an anti-icing layer arranged in sequence from inside to outside, wherein the anti-icing layer comprises the following raw materials by weight: 60-75 parts of fluorosilicon resin, 20-30 parts of methyl vinyl silicone rubber, 10-15 parts of SiO2-glass fiber gel, 5-8 parts of polypropylene fiber powder, 3-5 parts of nano SiO2, 4-6 parts of nano TiO2, 0.5-1 part of a dispersing agent, 0.5-1.5 parts of a flame retardant, 1-2 parts of a silane coupling agent and 1-2 parts of an antioxidant. The anti-icing cable has excellent hydrophobic property and anti-icing performance, and is excellent in insulating performance, high in compressive strength, high in flexibility and anti-aging; and the anti-icing layer of the anti-icing cable can replace the insulating layer in the cable and a sheath outside the cable, so that the cable mass is lowered and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the field of power cables, in particular to an anti-icing cable. Background technique [0002] Most of the existing power overhead insulated cables are composed of conductors and insulating layers, and are used for long-distance power transmission. This kind of cable can meet the requirements of safe power transmission under the weather conditions without ice rain, wind and snow. However, in actual operation, in the case of heavy snowfall and freezing rain, frost, ice and icicles will form on the surface of the cable, which increases the weight of the overhead insulated cable, resulting in broken wires or towers, and circuit interruption. Bring inconvenience to people's life, also cause huge loss to the country. The use of anti-icing machinery not only consumes a lot of manpower and material resources, but also has a slow cleaning speed, which cannot fundamentally solve the problem. Therefore, preparing anti-icing cables is a...
