Generator Transformers (VPI Dry Type)

Generator Transformers

Product RangeUpto 5 MVA
VoltageUpto 33KV

VPI Dry Type Generator Transformers are designed to connect generators to the electrical grid or plant distribution systems, efficiently stepping up or down the voltage as required. The VPI process ensures superior insulation, making these transformers ideal for high-current, high-temperature environments.

With their air-cooled, fire-safe design, they are suitable for power plants, renewable energy stations, and backup generator systems where oil-filled transformers pose a safety concern. They combine long-term reliability with low maintenance costs.
