Product details

Distribution transformers are essential for stepping down high-voltage electricity from transmission lines to lower voltages suitable for local distribution to homes, businesses, and industrial facilities. They are typically smaller than power transformers and feature components like an oil tank, conservator, Buchholz relay, and cooling mechanisms.

Frequently asked by buyers
What types of cooling mechanisms are integrated in these distribution transformers?

The distribution transformers use oil-immersed cooling mechanisms such as ONAN (Oil Natural Air Natural) or ONAF (Oil Natural Air Forced) cooling systems to maintain an optimal temperature during operation.

How does the Buchholz relay enhance the safety of these transformers?

The Buchholz relay acts as a gas actuated relay inside the transformer oil and triggers an alarm or trip in case of internal faults such as gas accumulation due to insulation failure, ensuring early fault detection and preventing major transformer damage.

What voltage levels can these distribution transformers handle?

These transformers typically step down from a primary voltage level up to 33 kV to a secondary voltage of 230/400 V, suitable for local distribution in residential and industrial setups.

What are the installation options available for these transformers?

Distribution transformers can be pole-mounted, pad-mounted, or installed in substations based on the site requirement and load conditions.

Are these transformers compliant with Indian electrical standards?

Yes, they are designed and manufactured to comply with Indian Standards (IS) and International Electrotechnical Commission (IEC) standards ensuring safety, reliability, and efficiency.
