Introduction to Products
The performances of our S9,S10,S11 series 20KV and 35KV three-phase oil-immersed  transformer conform to standards GB1094-1996 "Power Transformer" and GB/T6451-2008 "Technical Parameters and Requirements of Three-phase Oil-immersed Power Transformer". Its core is made of quality cold-rolled silicon sheet and is of a full-miter non-puncture structure and its coil is made of quality oxygen-free copper. It is artistic in appearance and sage in running and is widely used in transmission and distribution of industrial and agricultural networks.

Main Function and Features

High reliabity,advanced levelof performance,reasonable economical indicators
The core joints are of stepped shape with 3 steps,and the surface of the core is coated with cured paint to lower losses and noise.
The winding has novel structure and its oil passage is reasonable designed. Its newly designed insulation structure helps enhance its mechanical strength and the short circuit withstanding ability
The oil tank is in various types,all have good outlook.
