Advanced Outdoor Energy Transformer for Rectifier Duty Paper Mills

S11 Oil-Immersed Power Transformer

The S11-M series hermetically sealed oil-immersed power transformers offer low loss, low noise, and high efficiency, achieving excellent energy-saving effects and reduced pollution. Unlike standard transformers, the hermetically sealed design removes the oil conservator. Volume changes are automatically compensated by the corrugated oil tank sheets. This isolation from air prevents oil deterioration and insulation aging, significantly enhancing operational reliability.

Key Features:

• Laminated with high-quality cold-rolled silicon steel sheets to reduce no-load loss and noise.
• High and low voltage windings use oxygen-free copper for superior conductivity.
• Dyn11 connection group minimizes harmonic impact on the power grid.
• Hermetically sealed structure eliminates the need for core lifting or regular maintenance.
• Noise levels are measured significantly lower than international standards.
