sf6 o2 Maintance for Maintenance

sf6 o2 Maintance for Maintenance

SF6 has excellent properties for electrical insulation and the suppression of electrical arcs during switching. With the rapid increase in global electricity consumption, the demand for high voltage switches increases. For maintenance of high voltage switches, special recovery units with compressors and vacuum pumps are needed.
