Title:
POST INSULATOR AND MANUFACTURING METHOD THEREFOR, AND TRANSMISSION TOWER
Document Type and Number:
WIPO Patent Application WO/2021/238800
Kind Code:
A1
Abstract:
Specifically disclosed in the present application are a post insulator and a manufacturing method therefor. The post insulator comprises a post insulator body and an insulating sheath; the post insulator body comprises a first end used for connecting an electricity pylon and a free end opposite to the first end; and the free end is wrapped by the insulating sheath. By wrapping the free end by the insulating sheath, the use of an armour clamp structure for the free end can be avoided, thereby avoiding the possible occurrence of a floating potential and partial discharge of a metal component on the free end in high-voltage field strength, and preventing the rapid aging and even insulation failure of the product. In addition, by wrapping the free end by the insulating sheath, the occurrence of friction with wires and damage to the wires can be avoided. Also disclosed in the present application is a transmission tower.
