100kVA Distribution Transformer – Compact Three-Phase Oil-Immersed Solution

The 100kVA Distribution Transformer from Retrolex Transformers is a compact, three-phase, oil-immersed transformer designed for light commercial and industrial power applications. It is built for efficiency, safety, and long-term reliability. Moreover, it features an O.N.A.N. (Oil Natural Air Natural) cooling system, which naturally regulates operating temperatures without the need for fans or pumps. This energy-efficient design reduces maintenance requirements, lowers operational costs, and ensures stable performance across varying load conditions. In addition, it provides enhanced voltage regulation for sensitive electrical equipment, making it ideal for small-scale distribution networks.

The transformer supports standard high-voltage inputs of 6.6kV or 11kV and provides a 420V low-voltage output. Additionally, it includes essential protective and monitoring components such as a Conservator Tank, Buchholz Relay, Temperature and Oil Level Indicators, Pressure Relief Valve, Drain Valve, Cable Boxes, and an Off-Circuit Tap Changer. These features ensure safe, reliable, and low-maintenance operation. Furthermore, they support consistent energy delivery, long-term operational efficiency, and seamless integration with existing electrical networks. The transformer also protects connected equipment, complies with international electrical standards, and operates dependably under fluctuating load conditions.
