At the same time, the magnetic circuit serves as the basis for the installation and fastening of windings, taps, switches and other parts of the active part of the transformer. During the operation of the transformer, an electric field exists between its windings and the grounded parts, therefore, the magnetic circuit and its fastening parts must be grounded The shape of the parts forming the magnetic circuit, as well as the type and physical properties of the materials used for their manufacture, are determined by the purpose; design features of the circuit element. The magnetic core is assembled from separate thin plates of electrical steel, isolated from each other by a film of a special heat-resistant coating or varnish. The heat-resistant coating is usually applied directly at the steel plant; varnish film - at the transformer plant after cutting the plates. They are used in the manufacture of high-efficiency toroidal transformers.
