An improved clamping device for maintaining clamping pressure in a winding of a power transformer during its useful life. A remotely actuated hydraulic jack, or similar device, is used to initially apply a clamping force to the transformer winding. A spring-loaded mechanical follow-up device maintains the coil clamping force at a relatively fixed value when the remotely activated clamping force is relieved.
