10kV grounding switch
Product Overview
The JN15-12/31.5-210 series indoor high-voltage earthing switch (hereinafter referred to as the “earthing switch”) is a new type of earthing switch developed by our company through the introduction of advanced foreign technologies and in response to market needs. It is suitable for use in indoor 3–40.5 kV three-phase AC power systems operating at 50 (60) Hz, and is designed to be paired with various models of high-voltage switchgear. It can also be used for earthing purposes during maintenance of high-voltage electrical equipment. Comprehensive testing has demonstrated that its performance complies with the requirements of GB 1985 “AC High-Voltage Isolating Switches and Earthing Switches” and IEC 129.
