Product Details

Product Overview:

   Gas Vacuum Filling Device for Class IV Installation and Repair QualificationWith the rapid development of the power industry, and the increasing investment in equipment, especially the continuous increase of SF6 electrical equipment, the requirements for installation, commissioning, and maintenance of SF6 electrical equipment are getting higher and higher. To meet market needs, combined with our company's years of experience in testing, inspection, and related professional technical accumulation of SF6 electrical equipment, the vacuum filling device is mainly used in the production of electrical equipment manufacturing departments, and is also suitable for on-site installation and maintenance of 35kV~220kV GIS switches.

Mainly used for vacuuming and vacuum degree measurement during installation, operation, and maintenance of 35kV~220kV porcelain column SF6 circuit breakers, transformers, and other SF6 electrical appliances. It is a compact SF6 gas filling and evacuation device. The entire filling and evacuation device is mounted on a very sturdy metal trolley frame, which can move freely even on gravel roads.
