2000KVA 2500KVA 3150KVA Oil Immersed Step Down Transformer
Three Phase Distribution Transformer - 11KV/33KV
The 2500kVA and 3150kVA Step-Down Oil-Immersed Distribution Transformers are designed for medium- to high-capacity power distribution systems, providing reliable voltage reduction from 11kV or 33kV to low-voltage levels for industrial, utility, and infrastructure applications.
Robust Oil-Immersed Design
These transformers adopt a mineral oil–immersed structure, offering excellent heat dissipation and strong insulation performance. The oil-filled design ensures:
Stable operation under continuous and heavy load conditions
High resistance to short-circuit and thermal stress
Long service life with proven reliability
High Power Capacity & Electrical Stability
Rated capacity: 2500kVA / 3150kVA
Rated voltage: 11kV or 33kV (HV)
Three-phase configuration
Frequency: 50Hz or 60Hz (optional)
The optimized core and winding design delivers high efficiency, low losses, and stable voltage regulation, making the transformer suitable for demanding power distribution networks.
Strong Mechanical & Thermal Performance
Reinforced windings with high short-circuit withstand capability
Efficient cooling system (ONAN, optional ONAF)
Low temperature rise, supporting long-term overload operation
These features ensure reliable performance in industrial plants, substations, and utility networks.
Flexible Configuration & Customization
The transformer can be customized to meet specific project requirements, including:
Vector group selection
Impedance adjustment
Tap changer configuration (off-circuit or on-load)
Special insulation levels or environmental conditions
Typical Applications
Utility and grid distribution substations
Industrial power supply systems
Mining, oil & gas, and heavy industries
Large commercial and infrastructure projects
