Transformer Heating Oven Manufacturer, Supplier & Exporter in India
A transformer heating oven dries the core-coil assembly, windings and insulation (paper, pressboard) of distribution and power transformers before oil filling. Removing moisture from the insulation is essential to achieve the required dielectric strength and long transformer life.
MV International is a leading Transformer Heating Oven manufacturer, Transformer Heating Oven supplier and Transformer Heating Oven exporter based in Bahadurgarh, Haryana (Delhi NCR). Since 1989 we have designed, fabricated, tested and commissioned heat-processing equipment for more than 1,800 customers. Every Transformer Heating Oven is built in our own works, run-tested before dispatch and supported by our service team after installation.
How Our Transformer Heating Oven Works
The active part is lifted onto a trolley or placed by crane and heated with recirculated hot air, thermostatically controlled from room temperature up to about 200°C. A strong exhaust removes moisture, and a slow heating rate prevents damage to insulation. Ovens can be paired with vacuum drying systems for higher ratings.
