An insulator made by adopting the polymeric crystalline silicon insulator material not only can meet the electrical performance and the mechanical performance requirement of a conventional insulator, but also can meet a service life requirement, can also solve the electric corrosion resistance problem and the aging problem of a chute boot material under a direct-current voltage, has anti-fouling and self-cleaning functions, is high in cost performance, is energy-saving and environment-friendly and is free from pollution; after reaching a service life period, a product can be recycled.

Description

technical field [0001] The invention belongs to the technical field of insulators, and in particular relates to a polymer crystal silicon insulator material for direct current transmission and its preparation method and application. Background technique [0002] With the development of the economy, my country's demand for electricity continues to increase, and due to the extremely uneven distribution of my country's primary resources, power energy is mainly distributed in the southwestern and western regions, while power demand is relatively concentrated in the eastern and southern regions with better economic development This leads to inconsistencies in energy distribution and demand, and also makes long-distance and large-capacity power transmission inevitable. DC transmission is a very important means to solve long-distance, large-capacity, high-voltage and grid interconnection in the world's power power countries. The development of direct current transmission can be div...
