Background

Insulators are devices that are mounted between conductors of different potentials or between a conductor and a ground potential member and are able to withstand the effects of voltage and mechanical stress. The insulating control is a special insulating control and can play an important role in an overhead transmission line. Early-year insulators are mostly used for telegraph poles, and a plurality of disc-shaped insulators are hung at one end of a high-voltage wire connecting tower which is gradually developed, are used for increasing creepage distance and are usually made of glass or ceramics, namely insulators. The insulator should not fail due to various electromechanical stresses caused by changes in environmental and electrical loading conditions, otherwise the insulator will not function significantly and will compromise the service and operational life of the entire line.

According to the different geographic environment, some areas are in strong wind climate throughout the year, therefore when the insulator erects the high-voltage line at the high altitude, not only insulator itself receives strong wind to blow and produces and rock, and because the weight of high-voltage line is great, it is also great that the inertia that produces and rock is blown by strong wind, and the high-voltage line that rocks makes the insulator installation unstable, is easily damaged by strong wind.
