Description

technical field [0001] The invention relates to the field of novel composite materials, in particular to a composite material with excellent electrical insulation performance and a preparation method thereof. Background technique [0002] Ultra-high voltage refers to the voltage level from 330 kV to 765 kV, that is, various voltage levels such as 330 kV, 400 kV, 500 kV, and 765 kV. Ultra-high voltage transmission is an inevitable requirement for the increase of power generation capacity and power load, and the extension of transmission distance. EHV transmission is one of the important symbols of the development level of the electric power industry. With the extensive development of electric energy utilization, many countries are building large-capacity hydropower plants, thermal power plants, nuclear power plants, and power plant groups, and the power resources are often far away from the load center. Only by using ultra-high voltage power transmission can the power transm...
