Abstract: The solid insulation transformer (10) has a rectangular core (50) covered with a compressible closed cell foam to eliminate stress during curing of the cast dielectric material (18) surrounding the core and during operation. Heat pipes (22) are placed between the inner coil and the core to extract heat before the temperature builds up. For safety and to eliminate the need for a separate enclosure, an outer multilayer casing (16) having an incorporated grounding conductive layer is provided to cover the sides of the cast body. The outer casing prevents explosion if dielectric breakdown and arcing occur, and reduces the danger of electric shock.
