Abstract
The invention relates to a core rod of an ultra-high-voltage post composite insulator used for power transmission and transformation in the power industry and a manufacturing method thereof. The core rod consists of a rod core and a winding tube, wherein the winding tube is arranged on the periphery of the rod core and is a tube made by winding and curing a glass fiber yarn dipped with epoxy resin glue. The core rod is characterized in that the rod core is a core body with a damping slot on the surface thereof, and the winding tube consists of a layer I, a layer II and a layer III, and the three layers are respectively formed by winding and curing a glass fiber yarn dipped with epoxy resin glue.
