Three=phase power transformer with load-bearing rated coil former

摘要

A transformer structural arrangement comprising at least one coil bobbin (5-7) comprised of an insulating material of rugged composition and having at least one central recess which is enclosed by embedded windings and into which is inserted at least one linear side-limb of at least one separable, ring-shaped discrete core designed as a core column (1-4) made of a magnetically active material. At least one coil bobbin mechanically carries and supports the at least one discrete core.
