UI lamination cores

UI lamination cores



UI lamination cores are used as an alternative to EI lamination cores for single-phase transformers. They allow for the construction of slimmer transformers. In transformers with UI sheets, both arms of the U sheet bear a coil body each. UI sheets cannot be welded since the cut edges of the U and I sheets lie within the coil body. They therefore have to be reciprocally nested. This can be done manually or with a nesting machine.
