Do Epoxy Resin Insulators Retain Their Mechanical Strength After Being Damaged?

When high voltage epoxy resin is damaged, the glass fragments near the steel cap and iron foot are trapped, while the mechanical strength of the remaining part of high voltage standoff is still strong enough to prevent the epoxy resin insulator string from breaking, thereby improving the safety and reliability of power system operation. Therefore, regular inspection and maintenance are of great significance to extending its service life, maintaining its mechanical strength, and reducing the risk of failure.
