The Retrolex 2000kVA Distribution Transformer is a high-performance, three-phase oil-immersed transformer engineered for large-scale industrial, commercial, and utility applications. Designed to handle substantial electrical loads with exceptional efficiency, this unit delivers outstanding reliability, long service life, and superior thermal performance, even under the harshest operating conditions.

This transformer features a robust O.N.A.N. (Oil Natural Air Natural) cooling system, which enhances heat dissipation without the need for external cooling equipment—ensuring uninterrupted operation and reducing maintenance costs.

Equipped with dual high-voltage configurations (11kV / 33kV) and a low-voltage output of 420V, the Retrolex 2000kVA transformer offers flexible voltage transformation options tailored to diverse application needs. Its heavy-duty construction, premium insulation materials, and precision engineering guarantee consistent performance and enhanced safety.

Key built-in features include:

• Conservator Tank – Prevents oil spillage and maintains optimal pressure

• Buchholz Relay – Provides advanced gas detection and internal fault monitoring

• Temperature Indicator – Allows real-time temperature tracking for preventive maintenance

• Oil Level Indicator – Ensures safe operating oil levels are maintained

• Drain Valve – Facilitates easy oil replacement and servicing

• Cable Boxes – Protect and organize high- and low-voltage connections

• Pressure Relief Valve – Automatically releases excess internal pressure

• Off-Circuit Tap Changer – Enables voltage adjustment without energizing the transformer

Manufactured to meet SANS and IEC standards, the Retrolex 2000kVA transformer is designed for demanding environments such as mining operations, industrial plants, commercial power systems, and municipal substations. Whether used for new infrastructure projects or upgrading existing equipment, it offers a high-capacity, low-loss, and maintenance-friendly solution for power distribution.
