Summary
The three-phase oil-immersed distributing transformer applies new type insulating structure and makes 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 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 remarkable that it will save much of electricity consumption and operating cost.Product Description
Working conditions
The use conditions are according to IEC60076.Altitude is not over 1000m. Ambient temperature: highest temperature +40 C ;highest monthly average temperature+30 C.lowest temperature-25 C;highest yearly temperature: +30°C.
The wave curve of the power voltage is approximately sine wave. The voltage of three phase transformer should be approximately symmetrical.
