Abstract
A transformer tank for a shell type transformer includes a wall, the wall surrounding a tank interior, a clamping arrangement for exerting a clamping force on a magnetic core of the shell type transformer. The clamping arrangement includes a beam fixed on the wall, and a plunger, the plunger including a first axial end configured to exert the clamping force on the magnetic core. The plunger is movable with respect to the beam along its longitudinal axis and a value of the clamping force is settable depending on the position of the plunger relative to the beam.
