Porcelain insulators in electrostatic precipitator

Electrostatic precipitators (ESPs) are commonly the most used filtration technology at industrial environments considering that ESPs allow to have a high dedusting efficiency. ESP insulators are key components in a precipitator inasmuch as if they do not work properly, the efficiency decreases quickly, and even having an inadequate insulation can end up in a serious accident. Therefore, there are several recommendations given about the adequate material for each insulator type and also about how to maintain an ESP insulator in good working conditions.
