Application:
The HGC SF6 gas treatment cart is designed for the maintenance of SF6 (Sulphur hexafluoride) filled apparatus, such as gas-insulated transformers，Gas Circuit Breaker (GCB) and Gas Insulated Switchgear (GIS) etc. The HGC system can be used to vacuum, fill SF6 gas into new electrical equipment, and recover insulating gas from the SF6 apparatus in service. After purification, compress, and refill it back into equipment.
Feature:
. Vacuumize and monitor the vacuum degree of unit itself and electrical apparatus
. Recovering SF6 insulating gas from electrical equipment
. Dehydrating and filtrating recovered SF6 gas
. Vacuum filling SF6 gas into gas insulated device
