Product Details

Three phase oil-immersed distributing transformer S11-M 30 3150 series 380V control transformer

Product Description

The three-phase power distribution oil 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 highquality oxygenfree copper lines and oil immersed

transformer adopts multilayered drum type structure. All fasteners have been processedwith special treatment to prevent them from loosening.

As hightech product that promoted by the country, power distribution oil transformer has many advantages such as high efficiency, low loss. power distribution oil transformer social benefits are remarkable that it will save much of electricity consumption and operating cost.

1The performance of our S9 S10 S11 series 20kV and 35kV threephase oilimmersed transformer conform to the standardof GB 10941996 “Power Transformer “ and GB/T64512008 “TechnicalParameter and requirements of Three-phase Oil-immersed Power Transformer”.

2 The iron core is made of quality coldolled siliconsteel sheet , and the coil is made of

quality oxygen-free copper, featuring good outlook and safe running.

3The products are widely used in power transmission and distribution of industrial and agricultural power networks.

4Iron core is made of cold-rolled siliconsteel sheet with high conduction of magnetism and adopts

pulling-plank structure, so that its magnetic route is short, losses and noise level is low;

5Compress wire is adopted for winding so losses are low and have good ability withstand short-circuit;

6Its active part adopts special pressing method which could ensure reliable axial pressure;

7The oil tank is bell type with the structure of full folding plate type, having an excellent exterior and easy for maintenance;

8Reliability: All in-service product have no damages or oil leakage occurred;

9Oil tank with various kinds of structure and good appearance.
