| Brand | ROCKWILL |
| Model NO. | Oil-Immersed Electric Furnace Transformer for Steelmaking 10kV to 35kV |
| Rated voltage | 10kV |
| Rated frequency | 50/60Hz |
| Rated capacity | 4000KVA |
| Series | HSSP |
An electric furnace transformer is designed to step down the grid voltage to the operating voltage required by electric furnaces, delivering high, low-voltage current for applications such as steel-making furnaces, alloy furnaces, resistance furnaces, and salt bath furnaces.
Our electric furnace transformers are characterized by stable and reliable power supply, strong short-circuit resistance, and excellent thermal stability.
This power transformer is fully compliant with international standards including IEC 60076-1, IEEE C57.12.00, ANSI C57.12.90, AS/NZS 60076.5 and EN 61558-1. It meets quality requirements and is widely adaptable to the operational needs of power grids in multiple overseas regions.
