How To Effectively Extend The Lifespan Of Epoxy Resin Insulators?

When selecting materials for high voltage standoff insulators, epoxy resin systems with low bubble content and high cross-linking degree are preferred. Residual bubbles after epoxy resin casting will significantly accelerate insulation degradation. Properly controlling the curing process and avoiding micropore-induced cracking can delay internal stress accumulation.

Surface treatment for high voltage epoxy involves cleaning and the application of functional coatings. To address the flashover risk caused by 333 surface contamination, performance can be improved through hydrophobic coatings. Developing annual or periodic cleaning plans helps mitigate the corrosive effects of the external environment on epoxy resin insulator.
