The ZHN3-72.5 product is independently developed by our company, and it is the first time in the world that the solid sealing process of the vacuum interrupter is applied to the C-GIS product of the 72.5 kV voltage level, filling the international gap and leading the international technical level. Low-pressure SF6 gas is used as the insulating medium phase to phase and phase to earth of the switchgear, and the gas consumption is only 7% of that of similar products; the use of solid-sealed vacuum circuit breakers avoids the generation of harmful gases and greatly reduces the use and emission of SF6.
