The disconnector type GN30-12 is a rotating contact blade for indoor high-voltage switchgear, suitable for power systems with 50 Hz alternating current and 12 kV rated voltage. It is mainly used to open and close circuits under no-load conditions to achieve electrical isolation. Its compact design is suitable for installation in high-voltage switchgears, improving distribution system space utilization

Support manual control, control the movement of the blade by turning the handle.
Functions
Provide visible break points to ensure safe isolation during maintenance.
Low power circuits such as charging current and voltage transformers for splitting and combining buses.
Applications
- Built into indoor substations, switchgears and high-voltage switchgears.
- Places not subject to strong vibration, chemical corrosion and explosion hazards.
Precautions
- Working with the load is strictly prohibited: opening and closing must be done after the circuit breaker has been completely switched off.
- Maintenance requirements: Regularly check the condition of the contacts, the cleanliness of the insulators and the flexibility of the mechanism.
GN30-12 type disconnect switches are widely used in electrical isolation scenarios of indoor power systems due to their compact design and reliable operation. Selection should be based on current level, installation conditions and functional requirements
