Gas Insulated Switchgear Insulated Equipment for KEPCO

Gas Insulated Switchgear Insulated Equipment for KEPCO

• GITs can be installed together with gas-insulated switchgear in the same room because similar sf 6 gas pressures are used in these components. This can provide high compactness and flexibility in the design layout of the substation. •Gas-insulated on-load tap changers (OLTCs) with vacuum interrupters are used on GITs.
