Product Description

The S11-M-20 series 20kV oil-immersed transformer adopts high-permeability cold-rolled silicon steel core, full-oblique joint structure, which can effectively reduce losses. The windings are made of high quality oxygen free copper wire. The high voltage winding is of multi-layer cylindrical structure. All fasteners are specially treated to prevent loosening. This product has high efficiency and low loss, which can save a lot of energy and operating costs, and is the preferred choice for 20kV power distribution scenarios. At present, it is widely used in the urban power distribution network, industrial parks and new energy power plants around the world.
