Epoxy Resin Insulators Have Good Material Compatibility With Sf6 And Environmentally Friendly Gases.

high voltage standoff insulators exhibits stable electrical properties in the SF6 environment, mainly due to the strong electronegativity and inertness of the SF6 gas itself. This gas can effectively regulate the electronic accessory process and have a positive impact on the surface discharge behavior under a high voltage electric field, thereby reducing the phenomenon of local electric intensity concentration. Surface discharge mechanism experiments show that in gases such as SF6, ionized electrons on the resin surface are easily adsorbed by the gas, delaying the discharge development along the solid-gas interface. This demonstrates the favorable combination characteristics of high voltage epoxy with the SF6 environment.
