S9/S10/S11 Series Three Phase Oil Immersed Power Distribution Transformer
General
The three-phase oil-immersed distribution transformer applies new type insulating structure. The iron core is made high-quality cold-rolled silicon-steel plate. High-voltage winding group is made up of high-quality oxygen-free copper lines and it adopts multilayered drum type structure. All fasteners have been processed with special treatment to prevent them from loosening.
As high-tech product that promoted by the country. the product has many advantages such as high efficiency, low loss. Its social benefits are remarkable that it will save much of electricity consumption and operating cost.
Technical Datas
Note: High-pressure tap range: ± 5% or ± 2 × 2.5%; Frequency: 50Hz
