Abstract

An improved clamping means for retaining in position the windings of liquid-immersed electric induction apparatus of the high current type. Shock-absorbing spring clamps interposed between one end of power transformer windings and a portion of the frame resiliently exert a follow-up clamping force on the windings under steady state conditions and resist by dashpot action any transient or shock force tending to cause winding displacement, such as electromagnetic force under short circuit conditions.
