Oil Immersed Transformer

Xuri Electric manufactures full-series oil-immersed power transformers for industrial power stations, factory power distribution, mining, new energy and municipal grid projects.
This oil-immersed transformer adopts streamlined integrated overall design, symmetric radiators, neatly arranged high-voltage bushings and standardized auxiliary piping, delivering clean, elegant industrial appearance. It uses high-performance silicon steel core and sealed oil cooling system to realize stable voltage conversion, ultra-low no-load loss and long-term 24h heavy-load operation. We support complete customization of capacity, voltage grade and functional accessories to cover diversified project demands. Every transformer undergoes full insulation, temperature rise and partial discharge testing before delivery, with CE & ISO certification and 12-month global after-sales warranty.
