Description
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
  • Renewable energy grid connection system
Key Features
  • Robust oil-immersed construction for reliable operation
  • Efficient step-down voltage conversion (11KV/33KV)
  • Three-phase power distribution capability
  • Designed for industrial and utility applications
  • Available in multiple capacity options (2000KVA, 2500KVA, 3150KVA)
  • Durable construction for long service life
