The SGC1 single busbar switchgear is an armored metal-enclosed medium-voltage switchgear suitable for indoor installation. The structure of the switchgear is single-layer mid-mounted type. Each compartment is isolated from each other by grounded metal partitions. The components in the same compartment use air as the insulating medium.
The switchgear can be equipped with traditional transformers and protection relays, or with new sensors and intelligent control/protection units.
