The GN30-12 indoor rotary high-voltage disconnect switch is a new type of rotary blade disconnect switch. The main structure consists of two sets of insulators and contacts fixed on the upper and lower planes of a shared base frame. By rotating the blade, the switch can perform open and close operations. The GN30-12D model is an enhanced version that includes a grounding knife, meeting the diverse needs of different power systems. The product is compact, space-efficient, and offers strong insulation capabilities, making it easy to install and adjust. Its performance meets the requirements of GB1985-89 “AC High-Voltage Disconnect Switches and Grounding Switches” and is suitable for indoor systems with a rated voltage of 10kV and below, and an AC frequency of 50Hz. It can be used independently or in conjunction with high-voltage switchgear.
1.Altitude: Not exceeding 1000m.
2.Temperature Range: Ambient air temperature up to +40℃ and down to -10℃.
3.Relative Humidity: Daily average not exceeding 95%, and monthly average not exceeding 90%.
4.Seismic Resistance: Withstands seismic intensity up to 8 degrees.
5.Applicable Environments: Suitable for environments without severe dust, chemical corrosion, or explosive substances, and where there are no frequent severe vibrations.
•Ensure that the equipment meets the above environmental conditions during installation and use to guarantee optimal performance and safety.
•For use under special or non-standard conditions, please contact us to develop a suitable solution.
