yfpower on 13 Dec 24220kV Surge Arrester 220kv lightning arrester adopts the series structure of composite insulator and arrester, which is composed of lightning protection section, insulating section and connecting fittings, and integrates the functions of insulator support and arrester lightning protection. The lightning protection section is made of high-performance ZnO resistors set in an epoxy tube to absorb and discharge lightning energy, and a parallel protection gap is provided to prevent damage to the resistors when the lightning current is too large; the insulation section adopts an enlarged umbrella diameter and umbrella The spaced shed structure prevents icing bridging, improves the lightning resistance level of the line and the flashover voltage of icing and pollution.
