JDZ9‑3,6,10R 3‑10kV Indoor Cast Resin Voltage Transformer
Model and its meaning

Summarize
As industries continue to evolve and demand more efficient power solutions, voltage transformers will play an increasingly important role in ensuring the smooth and safe operation of power systems in all environments. Investing in high-quality voltage transformers is a positive step towards a reliable and efficient power infrastructure.
Safety is a top priority in electrical systems, and the voltage transformer design incorporates multiple features to enhance user safety. The terminal box, mounted on the transformer's secondary output terminals, provides a secure and organized space for wiring. Access holes on the front and sides of the terminal box provide easy access and connection to the output terminals. This thoughtful design not only ensures safe and reliable wiring but also minimizes the risk of accidental disconnection or short-circuiting, effectively preventing system failures or hazardous situations.

Structure and characteristics
This series of voltage transformers adopt a pillar structure and are fully enclosed with epoxy resin by epoxy casting. They are resistant to pollution and moisture and are also suitable for use in tropical regions. The transformers do not require special maintenance and only need to have their surface dirt cleaned regularly. At its primary output end, there are two easily replaceable fuses for short-circuit protection. The base plate of the product is equipped with grounding bolts and four installation holes for installation.
