DRY TYPE TRANSFORMER DESIGNED DETAILS

Low voltage windings

Low voltage windings are made of foil on automatic winding machine with simultaneous winding of interlaminar and frontal insulation. Ducts are provided with fiberglass profiles of a high heat resistance class. Windings are covered with insulating enamels and heat treated.

High Voltage winding

High voltage Windings are made in section-layer form with the series connection of sections. HV winding is made of insulated wire or foil on high accuracy coil-processing machines. Vaccum resin filling of windings is carried out during a completely automated process. Epoxy compound includes a number of components providing a good heat emission, and also a high thermostability.

Magnetic Core

Magnetic core is made of cold-rolled electrotechnical sheet steel with a heat proof coating. Stacking technology and step-lap cutting provide low level of no-load losses. Cutting of electrotechnical steel is carried out on the automatic cutting line with the high cut accuracy.
