Overall if we are to be checked on the ceramic insulator, then we have to use some method to ceramic insulators can be used even when the value of his features are reflected. Jiangsu Province Ceramics Research Institute Insulating Ceramics he is an insulating equipment, we can only be checked regularly, since he can ensure his quality and performance.
We have to look at the surface of the ceramic insulators usually used in negative net him, and if he is not clean insulating effect that will have some impact, if he installed the insulator leakage current loggers later, it is necessary for him to inspect the corresponding . He had no need to look skewed, the skew angle must not exceed 15 degrees, and if it is skewed too serious practical insulators be some impact.
But also on the Jiangsu Province Ceramics Research Institute ceramic insulator caps just feet and just check to see if there is no rust, just feet are not bent, etc., but also often the quality insulators and parts to check to make sure he was using when there will be no quality problems. We have to see if he has cracked ceramic insulators, in fact, burn marks or flashover and so will the quality of the child must have been affected.(picture/text http://www.jiangsuceramics.com/)
