35KV grade S9 series of oil-immersed power transformer
1. General
The three-phase oil-immersed distributing transformer applies new type insulating structure and makes short-circuit resistance strong. The iron core is made up of cold-rolled silicon-steel plate of high-quality. high –voltage winding group is made up of high-quality oxygen-free copper liner 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.
