Abstract

The invention discloses an insulating material, which belongs to the technical field of electric engineering. The insulating material is characterized by comprising, by weight, 20 to 28 parts of nanometer silica, 20 to 28 parts of polycarbonate resin, 1 to 3 parts of aluminum hydroxide, 10 to 20 parts of potter's clay, 80 to 100 parts of polyethylene, 1 to 5 parts of polyethylene glycol, 30 to 50 parts of silicone rubber, 2 to 5 parts of a vulcanizing agent, 4 to 8 parts of a diluent, 2 to 5 parts of fumed silica, 20 to 40 parts of a fire retardant, 20 to 40 parts of quartz powder, 4 to 8 parts of silicone oil, 54 to 72 parts of polyether-ether-ketone resin, 10 to 17 parts of talcum powder, 13 to 20 parts of light calcium carbonate, 9 to 18 parts of lubricant, 8 to 16 parts of anti-oxidant and 10 to 16 parts of calcined mica.

Description

technical field [0001] The invention relates to a material, in particular to an insulating material. Background technique [0002] With the rapid development of the national economy, people's electricity consumption has risen sharply, and the power system is also constantly developing and improving, so the requirements for power quality are getting higher and higher. In order to stabilize voltage fluctuations caused by unbalanced power generation and power consumption and ensure voltage quality, on-load tap changers are used in modern transformer equipment to regulate system voltage. [0003] The insulating material coated on the wall of the oil drum of the on-load tap-changer not only needs to be insulated, but also needs to be moisture-proof, anti-corrosion, and high-temperature resistant. At present, although there are many types of surface insulation materials on the market, their performance is relatively single, and their uses are highly targeted. They cannot meet the...
