Abstract

The invention discloses an insulating ceramic for a high-voltage power transmission line. The insulating ceramic is characterized by comprising a ceramic body, a semiconductor glaze coating the outer surface of the ceramic body, and an insulating layer attached to the outside of the semiconductor glaze. The outer surface of the ceramic body is coated with the semiconductor glaze, and the insulating layer is bonded outside the semiconductor glaze, so that the insulating ceramic has higher insulating performance, and the power transmission line winding the outer surface is prevented from generating electrochemical corrosion on the insulating ceramic, is safe to use and has long service life.

Description

technical field [0001] The invention relates to the technical field of insulating ceramics, in particular to a special insulating ceramic for high-voltage transmission lines. Background technique [0002] Insulators are special insulation controls that can play an important role in overhead transmission lines. Insulators were mostly used on utility poles in the early years, and gradually developed into high-voltage wire connection towers where many disc-shaped insulators were hung at one end. It was used to increase the creepage distance and was usually made of glass or ceramics. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions, otherwise the insulator will not play a significant role and will impair the service and operating life of the entire line. [0003] However, existing insulators are prone to defects such as leakage, galvanic corrosion, and surface dirt during use, and generally ...
