25kVA Distribution Transformer

25kVA Distribution Transformer – Reliable Small-Scale Power Distribution

The Retrolex Transformers 25kVA Distribution Transformer is a compact, three-phase, oil-immersed transformer designed for small commercial, residential, and light industrial power distribution. It is engineered for efficiency, safety, and long-term reliability.

This transformer features an O.N.A.N. (Oil Natural Air Natural) cooling system, which naturally dissipates heat without fans or external cooling equipment. As a result, it ensures stable voltage regulation, reduces maintenance requirements, lowers operational costs, and provides reliable performance even under fluctuating load conditions. Moreover, it is built to withstand environmental challenges such as temperature variations, humidity, dust, and other harsh conditions, ensuring uninterrupted service.

Supporting standard high-voltage inputs of 6.6kV or 11kV and providing a 420V low-voltage output, the 25kVA Distribution Transformer includes essential protective and monitoring components. These consist of a Conservator Tank, Buchholz Relay, Temperature and Oil Level Indicators, Pressure Relief Valve, Drain Valve, Cable Boxes, and an Off-Circuit Tap Changer. Collectively, these features provide safe operation, simplified maintenance, and long-term reliability for small-scale networks.

Overall, the Retrolex Transformers 25kVA Distribution Transformer delivers dependable, efficient, and safe energy distribution. It ensures reliable service, reduces operational costs, protects connected equipment, and maintains consistent power quality for residential, commercial, and light industrial applications.
