                S11-M Off-load Distribution Transformers

                  Brief  introduction

                • S11-M series integrate state-of-the-art transformer design and construction. Compared to S9-M series, S11-M series are more efficient, no-load loss is reduced by 20 %. Since its high performance in energy saving, the product is recommended by China Machinery Industry Federation (CMIF).
                • The products can be used in various fields, possible applications includes: industrial and petrochemical plants, railways, coal mines and other industries, public places, indoor or outdoor unit substation, it can be especially used as rural and urban power grid distribution equipment.

                  Features

                • High-quality corrugated tank with modern folding technology, compact airtight preventing early oil aging.
                • Cold-rolled grain-oriented high-silicone-content steel, step-up lamination, low no-load loss, and low no-load current.
                • First Grade oxygen-free copper, new windings structure.
                • Newly designed insulation structure with improved life expectancy, High mechanical withstand capability.
                • Cost-effective: 30% reduction on energy compared to conventional type.
