Frequently Asked Questions
A Power Transformer is a high-voltage, high-capacity transformer used to transfer electrical energy between generation, transmission, and distribution networks.
Power Transformers are designed for high voltage (≥33kV) and continuous operation at near full load, while Distribution Transformers operate at lower voltages and varying loads.
Power Transformers range from 160 kVA up to 1500 MVA, and voltage class from 12 kV to 1200 kV.
In generation stations, transmission substations, industrial plants, and renewable energy grids.
High-grade Hi-B CRGO silicon steel cores and copper/aluminum windings with Class F or H insulation.
ONAN, ONAF, ODAF, ODWF, and OFAF cooling systems depending on capacity and installation conditions.
