For a 10 MVA unit, price is driven by voltage class (e.g., 11/33 kV vs 33/132 kV), cooling type, loss guarantees, and additional features like OLTC, monitoring, and special bushings. Regional manufacturing costs and logistics (road/port access) play a role. If the transformer must meet strict noise limits, seismic standards, or have low loss values, design complexity and material quantity increase, raising price. Utility project volume and long-term framework agreements can secure better pricing.
