Abstract
Fluid-filled electrical apparatus suitable for use in harsh environments. The electrical apparatus includes a tank having bottom and side members whose configuration provides corrosion protection for the electrical apparatus. A plurality of radially spaced, annular shoulders in the bottom member, with flanges therebetween, define a configuration wherein the innermost circular-shaped portion of the bottom member fits with the cylindrical side member with the lower edge of the side member disposed in proximity to one of the flanges in the bottom member to form a joint suitable for welding. The outwardmost flange of the bottom member extends downward from the joint and beyond the side member to provide an edge or rim upon which the entire tank rests and, further, presents sacrificial metal to the environment which protects the joint despite corrosion of the outermost flange.
