How Epoxy Resin Insulators Reduce Radio Interference

The optimized surface geometry of material high voltage standoff and the arrangement of the epoxy resin skirts increase the distance along the skirts and lengthen the leakage path, effectively reducing the probability of discharge current being converted into radio frequency radiation. This aligns with the national standard requirement for measuring RIV under the applied voltage in the high-voltage high voltage standoff insulators radio interference test.

Material high voltage epoxy possesses excellent electrical insulation and tracking resistance. Compared to traditional materials, material epoxy resin insulator exhibits a higher corona initiation voltage under high-voltage conditions, reducing the possibility of discharge between the conductor, insulator, and ground, which could then lead to radio interference (RIV) conduction.
