Strip wound coil with reinforced edge layer insulation

摘要: A dry type transformer has an iron core, high voltage windings embedded in cast resin, and low resin encapsulated. The winding is constructed with flexible sheet conductors coincident layer insulation sheets that extend beyond the edge of conductor. Cooling air ducts are fabricated as it wound. To prevent extension from collapsing over formed during a vacuum pressure impregnation process, reinforcing means added to extensions them collapsing.
