Power transformers are essential electrical devices designed to transfer electrical energy from one circuit to another at different voltage levels efficiently. Specifically engineered for high-capacity electrical distribution, these transformers operate in the range from 5MVA 33KV up to 25MVA 66KV and are ideal for primary distribution networks. They facilitate voltage step-up and step-down processes, enabling seamless energy transmission between generating stations and distribution networks. Our oil-cooled (ONAN) 3-phase power transformers provide reliable performance with enhanced cooling efficiency, ensuring durability and operational stability under heavy load conditions. These transformers are crucial components in electrical substations and power plants, optimizing the transmission and distribution of electricity across grids.
