Abstract

763,349. Transformers. REYROLLE & CO., Ltd., A. Nov. 8, 1954 [Nov. 13, 1953], No. 31589/53. Class 38 (2). A polyphase voltage transformer has the high voltage phase windings 30 and any connections 32, 34, 35 to them all embedded in a single block 36 of low moulding pressure synthetic resin, the high voltage terminal bushings 38 being moulded integrally with the block. The magnetic core having the low voltage windings wound thereon is accommodated in the tunnels 37 in the block.
