Problems solved by technology

Insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions, otherwise the insulator will not have a significant effect and will damage the service and operating life of the entire line
[0003] The insulation performance of the insulators in the prior art is not high enough, and it is easy to generate leakage and galvanic corrosion during use, which reduces the durability of the product, resulting in a lower product life and higher replacement costs

Abstract

The invention discloses an insulating ceramic for high voltage transmission lines. The insulating ceramic comprises, by weight, 20-30 parts of mica powder, 10-15 parts of titanium dioxide, 5-10 partsof calcined talc, 5-10 parts of calcite, 15-25 parts of alumina, 5-10 parts of cobalt oxide, 10-15 parts of calcium carbonate, 10-15 parts of barium carbonate, 3-5 parts of silica, 10-20 parts of Herbof Air-plant, 15-20 parts of Arabic gum and 5-10 parts of a gloss agent. The invention also discloses a preparation method of the insulating ceramic for the high voltage transmission lines. The insulating performance of the insulating ceramic prepared in the invention is significantly improved under the joint action of all above raw materials, so the breakdown phenomenon does not occur even underthe action of strong electric power; and the insulating ceramic has the advantages of effectively improved wear and corrosion resistance, keeps a high smoothness for a long time, and has high hydrophobicity.

Description

technical field [0001] The invention relates to the technical field of insulating materials, in particular to an insulating ceramic for high-voltage transmission lines and a preparation method thereof. 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] The insulation performance of the insulators in the prior art is not high enough, and leakage and galva...
