Feature
The three-phase S9/S10, S9-M series oil-immersed distributing transformer applies new type insulating structure and makess short-circuit resistance strong. The iron core is made of 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 typet structure. All fasteners have been processed with special treatment to prevent them from loosening.
As the 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.
