Product Description
GN19-12, 12C Series Indoor High-Voltage Disconnect Switches
GN19-12, 12C Series Indoor High-Voltage Disconnect Switches
The GN19-12, 12C series indoor high-voltage disconnect switches, manufactured by Yueqing Liyond Electric Co., Ltd., are designed for indoor use with a rated voltage of 12kV, three-phase AC 60Hz. These switches are used for dividing and closing circuits under voltage and no load conditions.
Features:
- Three-pole type structure
- Consists of base frame, rotating shaft, lever, porcelain pillar insulator, gate knife, and connection board
- Conductive part fixed on the base by pillar insulators
- Improved mechanical strength and heat dissipation area of contact knife
- Models available: GN19-12/400, 630, 1000, 1250
Working Principle:
The conductive part of the disconnect switch is fixed on the base by insulators, with contact knives connected to tie insulators and the spindle. The spindle is linked to the moving mechanism through the handle, ensuring stable operation.
Model Meaning:
The model numbers of the disconnect switches indicate the rated current capacity, with variations in features such as magnetic locking plates for enhanced safety.
