Three-phase autotransformer offer dry autotransformer legend dry autotransformer ..

Main features: a variety of power transformers are the main components and electrical equipment, the company's use of advanced production technology; and import Spanish Winder and full vacuum pressure impregnation equipment; windings are born out of the whole column winding method; transformer vacuum impregnation paint, the transformer insulation level to F or H grade. Output and input voltage transformer according to design. There are single-phase, three-phase or multiple inputs and outputs and other specifications, rated power up to 200KVA. Widely used in lighting, electrical machines, machinery and electronic equipment, medical equipment, rectifier devices. Product performance can meet the special requirements of various technical parameters user:??
