The S11-M series fully sealed oil-immersed power transformers developed by our company feature low losses, low noise, and high efficiency, delivering significant energy savings while reducing environmental impact. Compared to conventional oil-immersed transformers, these models eliminate the oil reservoir; oil level variations are automatically compensated through the elasticity of corrugated plates in the tank. The transformer is completely isolated from air, preventing oil degradation and insulation aging, thereby enhancing operational reliability and requiring no maintenance during normal operation.

The 35 kV series oil-immersed power transformers feature advanced design with significant improvements in materials, structure and manufacturing processes. High-and low-voltage clamps are secured using steel tension bands or upper/lateral beams, forming a robust frame structure that enhances core clamping strength and resistance to transportation impacts. These transformers demonstrate strong short-circuit resistance, an aesthetically pleasing
