Frequently Asked Questions (FAQ)

We've compiled some common and critical questions about the JN22-40.5/31.5 Indoor High Voltage Grounding Switch to assist you:

• Q1: What is the primary function of the JN22-40.5/31.5 grounding switch, and why is it essential for 35kV systems?

• A1: The primary function is to provide a safe, visible, and reliable grounding path for high-voltage circuits (up to 35kV) after they have been de-energized. It's essential to rapidly discharge any residual voltage and prevent accidental re-energization during maintenance or repair work, thereby ensuring the safety of personnel and preventing equipment damage.

• Q2: How does the mechanical interlock system of this switch enhance safety?

• A2: The mechanical interlock system is a critical safety feature that physically prevents incorrect operational sequences.
