Abstract
The invention relates to insulators of electric appliances of high voltage power stations and particularly relates to a high voltage casing pipe. The high voltage casing pipe utilizes a pure dry-type insulating structure which does not need to be charged with oil and air, so that environmental pollution is small and maintenance times of a device are fewer. In the meantime, the high voltage casing pipe can effectively avoid explosions when a breakdown occurs, so the operation becomes safer and more stable. The high voltage casing pipe comprises a capacitance core and a full skirt assembly. An insulating layer is arranged inside the capacitance core. The insulating layer inside the capacitance core is an insulating layer which is formed by soaking glass fibers in epoxy resin. The full skirt assembly is a silicon rubber full skirt assembly. The high voltage casing pipe is widely applied to the insulators of the electric appliances of the high voltage power stations.
