Product Description

The TFS-M-200/15 oil-immersed power transformer is a high-efficiency distribution transformer engineered for reliable performance in power networks. Designed with advanced amorphous alloy core technology, it achieves exceptionally low no-load losses and reduced load losses, significantly minimizing energy waste during operation. This transformer features optimized thermal management for stable low-temperature rise, along with low-noise characteristics suitable for residential or sensitive environments. Its robust construction ensures resilience against electrical stresses and operational fluctuations, aligning with international safety and durability standards. Particularly effective in scenarios with prolonged low-load conditions—such as rural grids or distributed renewable integration—it supports sustainable energy infrastructure. Compliant with stringent certification requirements, this 200 kVA/15 kV class unit exemplifies cutting-edge, eco-conscious power distribution solutions for modern grids.
