The transformer does not require special maintenance, only periodic cleaning of surface contaminants. JDZ9-3, 6, 10 voltage transformers are equipped with a terminal box at the secondary terminal outlet. The terminal box has holes on the front and side for connection, ensuring safety and reliability. The product base is equipped with a grounding bolt and four mounting holes.

Outline Drawing and Installation Dimensions

Ensure that the JDZ9-3, 6, 10KV high-voltage voltage transformer is suitable for 3～10kV ungrounded systems, with the rated voltage ratio customized according to the order. During installation, verify the nameplate parameters. The secondary side must never be short-circuited. If the secondary voltage deviation exceeds ±0.5% during operation, the accuracy should be verified after power-off.
