Technical Parameters

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. JDZX10-3, 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 JDZX10-3, 6, 10 voltage transformers have a rated voltage ratio of 10/√3/0.1/√3kV and an accuracy class of 0.5/3P. During installation, the distance from the primary high-voltage terminal to ground should be ≥125mm. The secondary load should not exceed the rated capacity, and the junction box moisture-proof sealing gasket should be intact.
