1250kVA Distribution Transformer – Reliable Power for Industrial and Commercial Networks

The Retrolex Transformers 1250kVA Distribution Transformer is a robust, three-phase, oil-immersed transformer engineered for efficient and reliable power distribution in large industrial, commercial, and utility-scale applications, another one of our most popular options. Designed for optimal performance, safety, and longevity, this transformer features an O.N.A.N. (Oil Natural Air Natural) cooling system, which naturally dissipates heat without the need for mechanical cooling equipment. This energy-efficient cooling system ensures consistent operating temperatures, reduces maintenance requirements, lowers operational costs, delivers stable performance even under fluctuating load conditions, and provides enhanced voltage regulation, improved energy efficiency, and reliable protection for sensitive connected equipment, preventing operational interruptions.

Supporting a high-voltage input of 33kV and a low-voltage output of 400V, the 1250kVA Distribution Transformer is constructed from premium-grade materials for durability and long-term reliability. It incorporates essential components such as a Conservator Tank, Buchholz Relay, Temperature Indicator, Oil Level Indicator, Pressure Relief Valve, Drain Valve, Cable Boxes, and an Off-Circuit Tap Changer. Together, these features ensure safe operation, simplify maintenance, and protect connected equipment, even in demanding industrial or commercial environments.
