advantages of Gas Insulated Switchgear Density Monitors

Electrical Clearance: Insulating gas insulation performance is far stronger than air, the electrical clearance of fully insulated switchgear is far less than semi-insulated cabinet Equipment Size: Because of the small electrical gap, the size of the air insulated switchgear is far less than the same voltage level of the semi-insulated cabinet, occupying a small area.
