Industrial furnaces demand more than a standard power transformer. Their electrical loads can be intensive, fluctuating, and highly sensitive to voltage stability. A purpose-built furnace transformer helps convert medium-voltage supply into the lower voltage required by furnace equipment while supporting dependable plant operation.

Designed for High-Voltage Furnace Applications

This oil-immersed transformer is configured for a 35 kV input and 50 Hz frequency, with selectable output voltage options of 234 V, 405 V, and 540 V. Its rated capacity is 12,000 kVA, making it suitable for demanding industrial power systems where substantial energy transfer is required. The two-winding design provides a practical foundation for integrating the transformer into a dedicated furnace power circuit.

Construction details are important when a transformer is expected to operate under heavy industrial conditions. The unit uses 100% copper winding material and silicon steel sheet for the magnetic core. OFWF cooling is specified to support heat management during operation, while the listed GB1094 and GB/T6451 standards provide a reference point for technical review and project documentation.

Practical Purchasing Considerations

For importers, distributors, and project procurement teams, the available voltage configuration can simplify equipment matching across different furnace systems. Before placing an order, buyers should confirm the required output voltage, connection arrangement, installation environment, cooling requirements, protection scheme, and local compliance documentation. The listed connection symbols include Dd0 and Ii0; final technical selection should be checked against the complete electrical design.

Whether you are sourcing for a furnace manufacturer, an industrial EPC project, or a regional distribution program, this 35kV transformer offers a focused solution for medium-voltage power conversion.
