Abstract

552,778. Transformers; reactors. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 27, 1941, No. 15262. Convention date, Nov. 29, 1940. (Class 38 (ii)] In transformers or reactors having a circular winding structure 11 to which cores 12 ... 15 of spirally wound strip are applied as described in Specification 545,229, sections of each core are displaced laterally so that the cores interfit and thus improve the space factor within the winding window. A cooling duct 25 is formed in the middle. In a modification, Fig. 4, three cores 30 are provided with successive layers of strip displaced laterally so that the cores interfit to produce a hexagonal arrangement within the winding window.
