Furnace Duty
Transformer
Any furnace that uses voltage other than standard commercial power needs a furnace transformer. For both home as well as industrial furnaces, our transformer changes the voltage of the input power to a different voltage for use within the furnace.
Advantages
- Trouble-free performance during surges and frequent short circuits
- High current at low voltages
- Optimum utilisation of active materials for compactness
Key Features
- Designed for induction furnace, arc furnace, and submerged arc furnace application
- Magnetic circuit: CRGO lamination M3 to M5 type
- Transformer type: Dry or oil-cooled
- Electric circuit: Electrolytic grade 99.9% pure copper with transposition in LV coil for current sharing in parallel conductors
- Dielectric circuits: Electric grade press paper, boards, and mineral oil
- Thermal circuit: Adequate cooling ducts provided radially and axially for smooth internal oil flow
- Radiator cooling banks provided for natural air cooling ONAN and additional fans for ONAF cooling
- High current transformers provided with OFW cooling
