Product Introduction Gas vacuum and filling device adopts high-quality vacuum pump, fast pumping speed, no need for oil smoke, no noise, no dripping oil leakage and other advantages, because of the easy to use closed structure design, avoid external collision, so that the internal pipeline and electrical components can be protected, so that the machine with long service life can be increased, and the performance is superior. Gas vacuum and charging devices are mainly used in power supply enterprises, power transmission and transformation engineering companies, power plants, ultra-high transmission substations, SF6 electrical switch manufacturing plants and other departments, as auxiliary equipment used in installation, GCBP, GCBT, GIS and other SF6 electrical adjustment and maintenance products. This equipment is used to vacuum and replenish SF6 gas operation above electrical products, and this equipment can also be used as vacuum and inflatable equipment for other sectors.
