Design & Construction

As we all know, the construction, rated power, voltage level and scope of the application are all key factors that determine the transformer’s design. The transformer is mainly composed of winding and magnetic core. The winding is usually made of electrolytic copper of a high conductivity and insulation material. The magnetic core is usually made of laminations of non-ageing, cold-rolled, grain-oriented, silicon steel of high permeability without burrs.
