í‚800kV ultra-high voltage DC synthesized insulator

This invention relates to insulator technique field and to one insulator of +-800kV with direct current, wherein, the umbrella cover uses 110-2-methyl-vinyl ketone as base and adds strengthening agent gas phase white carbon and aluminum hydroxide powder and proper assistant agent and sulfuration agent for mixing; using total injection process to make the silicon glue under high pressure into umbrella cover on the mill surface with continuous distribution with ball heads and ball socket structure ware into one integrated insulator.
