1. SFZ9-35 Type 33kv 35kv Oil Immersed 3 Phase Oil Type Power Transformer
The three-phase oil immersed distributing transformer applies new type insulating structure and makes short-circuit resistance strong. The iron core is make 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.
We can supply S10 series, S11 series, S13 series, S15 series, S16 series, high voltage and capacity regulating transformer, furnace transformer, oil field transformer etc.
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 is will save much of electricity consumption and operating cost.
