GN22-12 Three-phase Isolating Switch 6300A High Current Indoor High Voltage

    GN22-12 (C) (D) series indoor high-voltage disconnector high-voltage switchgear is used in power systems with rated voltage of 12kV, 50Hz and below, to connect, disconnect or convert lines under voltage but no load.

Matching mechanism: Equipped with CS6-1, CS6-2 and other manual operating mechanisms, and electric operating mechanisms can also be used.

   This series of switches are operated by CS6-2 manual operating mechanism or electric operating mechanism, and can be installed on the left or right side of the disconnector.

Structural features

This product is a high-current isolating switch with a three-phase common bottom knife structure. It adopts a mechanical locking prototype with a two-step action of closing and contacting, achieving wear-free contact, small operating force, high contact pressure, and good dynamic thermal stability.

Application Areas:

Switchgear Systems: Used in metal-enclosed switchgear for isolating and protecting electrical circuits.

Power Distribution Equipment: Ideal for use in power substations, ensuring safe isolation of the circuit during maintenance.

Electric Power Plants: Utilized in indoor applications where high-voltage electrical isolation is required for safe operations and maintenance.

Transformer Stations: Applied in transformer substations for safe isolation of transformer circuits.

Renewable Energy Installations: Can be used in energy storage or renewable energy systems like solar and wind farms for protection and isolation during maintenance.
