Abstract (en)
[origin: EP1808872A2] The invention relates to a clamping, compacting and lifting system for electric transformers and reactors, of the type wherein the magnetic core (1) is equipped with lamination stack clamps (2) maintained in position through tie rods (3). Said system is characterised in that the transformer is lifted by means of constraints between the lamination stack clamps (2.1, 2.2) and the magnetic core (1), such constraints being comprised of pins (4) protruding from the internal part of the lamination stack clamp sections which are inserted into corresponding housings (5) drilled in the magnetic core.
