                35Kv Class
                S11 35kV Series
                SZ11 10/35kV Series
                SZ11 10/35kV On-Load Distribution Transformer

                  Brief  introdution

                • Using advanced production equipment and manufacturing processes, along with high quality materials, 35kv series three phase transformers are low loss, low noise transformers with high level of anti-lightning capability to withstand sudden short-circuit. The online monitoring and distance control functions make the unmanned station workable. The product is tested and certified by China National Transformer Quality Supervision Testing Centre.(CTQC).

                • Product is suitable for three-phase 50HZ, 35KV voltage level distribution system of urban and rural industry and agriculture, it is also applicable in mining, petrochemical industries, power plants and electricity distribution works, package substations and other applications.

                  Features

                • Core made of high quality cold-rolled silicon steel, step-up lamination which significantly reduce the no-load loss and no-load current and noise.
                • High quality oxygen-free copper wire for both high and low voltage winding to ensure low resistance and load loss.
                • New winding structure, properly designed tap zone and oil duct layout to improve the mechanical strength and resistance to sudden short-circuit.
                • Pleasing-appearance, conventional-type or bell-type structure corrugated oil tank.
