Our company manufactures three-phase oil-immersed power transformers rated at 110 kV and below. Leveraging our advanced computational and verification software, we conduct comprehensive optimization and validation of key components—including the core, windings, tank structure, lead connections, and oil tank—and perform unit-by-unit checks on electric fields, leakage magnetic fields, temperature distributions, and electromagnetic forces during operation, thereby ensuring that all performance parameters meet stringent standards. State-of-the-art process equipment, meticulous material selection, and highly efficient manufacturing processes combine to deliver products of superior quality that are energy-efficient and environmentally friendly. These transformers are ideally suited for use in power plants, substations, and large industrial, mining, and petrochemical enterprises. Our 35 kV and lower distribution transformers represent the latest series of low-loss copper-wound models. Made from premium materials and incorporating innovative processes and new insulating materials in the winding assembly and insulation systems, these transformers achieve significantly reduced no-load and load losses while offering enhanced reliability and superior performance and structural integrity.
