Abstract
This invention involves a compound and hollow insulator and its manufacturing method thereof. The insulator includes a connector, an insulating tube and petticoat. The insulating tube is made by winding epoxy glass fiber. The petticoat is arranged outside the insulating tube. The connector is arranged at the two ends of the insulating tube. The petticoat becomes an integrated body through injecting silicon sulfide rubber at the high-temperature so that the electrical and mechanical property is better. Meanwhile, the ratio of the qualified products is improved.
