Oil Filled Transformer Manufacturer
We are a professional manufacturer of three-phase oil-immersed distribution transformers. Our transformers feature a new insulation structure that enhances short-circuit resistance. The core is made of high-quality cold-rolled silicon steel sheets, and the high-voltage winding uses high-quality oxygen-free copper wire in a multi-layer circular structure.
