Product Introduction:
The SZ11-35 series 35kV oil-immersed on-load tap-changing transformer adopts high-permeability cold-rolled silicon steel core and fully oblique joint structure to effectively reduce loss. The windings are made of high quality oxygen-free copper wire and the high-voltage winding is of multi-layer cylindrical structure. All fasteners are treated specially to loosen. This product is high efficiency and low loss, greatly save energy and operating costs, the first choice for medium-voltage power distribution scenarios. It is widely used in the world in substations, load centers and new energy power plants.
