|---|---|
The GN30-12 Indoor Rotary High Voltage Disconnector is a new-generation isolator switch designed with a rotary blade mechanism. Mounted on a three-phase common base frame, it features upper and lower planes equipped with two sets of insulators and contacts. Circuit isolation is achieved by rotating the blade to complete the opening and closing operation.
The GN30-12D model includes an additional grounding knife, meeting the diverse requirements of modern power systems. With its compact design, strong insulation, and easy installation, the GN30-12 disconnector is widely used in indoor 12kV, 50Hz AC power systems. It can be applied both independently or as part of high-voltage switchgear to provide reliable circuit isolation under no-load conditions.
Rotary blade mechanism ensures smooth and reliable switching operation.
Compact structure with small footprint, ideal for indoor installations.
Strong insulation capability, ensuring high operational safety.
Available in standard GN30-12 and enhanced GN30-12D with grounding knife.
Easy installation, adjustment, and long service life.
Meets GB1985-89 and other related technical standards.
Indoor 12kV, 50Hz AC power distribution systems.
Circuit isolation under no-load conditions.
Suitable for integration with high-voltage switchgear or independent use.
Reliable isolation for system maintenance and operational safety.
Rated Voltage: 12kV
