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. 

Description provided by Paramex Transformers Ltd.

Frequently asked by buyers
What voltage levels do the distribution transformers support?

Distribution transformers typically support high voltage input levels such as 11kV or 33kV and step these down to low voltage outputs ranging from 400V to 440V for safe local distribution.

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

The Buchholz relay detects gas accumulation caused by internal faults or oil leakage within the transformer and triggers an alarm or disconnects the transformer, thereby preventing catastrophic failures.

What cooling methods are used in these distribution transformers?

These transformers use oil cooling methods such as Oil Natural Air Natural (ONAN) or Oil Natural Air Forced (ONAF) to dissipate heat generated during operation and maintain safe temperature levels.

Are distribution transformers suitable for both pole-mounted and pad-mounted installations?

Yes, distribution transformers are designed to be versatile and can be installed either as pole-mounted or pad-mounted units depending on the site requirements and ease of access.

What standards do these distribution transformers conform to?

These distribution transformers are manufactured in compliance with Indian Standards IS 1180, IS 2026, and relevant IEC standards ensuring safety, reliability, and performance.
