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. JDZX9-10 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 JDZX9-10 voltage transformer has its primary winding reliably grounded during installation. The secondary terminal tightening torque should meet the requirements, and the nameplate ratio should match the system voltage. During operation, measure insulation resistance annually (≥1000MΩ with a 2500V megohmmeter), and partial discharge ≤10pC is considered合格.
