Structure and Features
This series of voltage transformers has a post-type structure, using epoxy resin fully enclosed casting, resistant to pollution and moisture. It is also suitable for use in tropical regions. The transformer does not require special maintenance, only periodic cleaning of surface contaminants. JDZ10-3, 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 six mounting holes.
Outline Drawing and Installation Dimensions

Ensure that the JDZ10-3, 6, 10 voltage transformers have a switchable accuracy class combination of 0.5/3P, suitable for 3~10kV power systems. During installation, ensure the nameplate ratio and rated capacity match the system, and the secondary wiring polarity is correct. The secondary side must never be short-circuited, as this will burn the windings.
