摘要： A transformer tank for a shell form transformer, for housing an active part of a three-phase transformer including transformer phases is provided. The tank includes a bottom tank part and a medium tank part comprising bottom plate and walls, a cover plate, reinforcing beams joined to the walls, interphase plates and stiffening supports for strengthening the cover plate. The interphase plates are to be arranged in a lower space of the tank, between adjacent transformer phases, extending from one wall to an opposite wall of the tank and coupled to the reinforcing beams. Each stiffening support is to be coupled to an interphase plate and extends in an upper space of the tank between the interphase plate and the cover plate, to cooperate with the cover plate. A three-phase shell form transformer and a method to assemble the transformer are also provided.
