Copper Electrical Power Transformer 6K - 11Kv 25Kva - 800Kva Oil Power Transformers
1. General
The three-phase distribution transformer applies new type insulating structure and makes short-circuit resistance strong. The iron core of distribution transformer 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 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 distribution transformer will save much of electricity consumption and operating cost.
