Distribution transformer having inner and outer low-voltage winding sections and a high-voltage winding section disposed therebetween. Insulation structures separate the various winding sections and include a relatively small thickness of solid insulating material and a liquid dielectric duct. Some of the solid insulating material is axially extended to increase the creep resistance of the winding. The insulation structures are also void of any metallic electrostatic shield or any other member which would hamper adequate processing of the insulation structure during the construction of the transformer.
