Abstract
An electrical transformer winding can be mounted in its finite form onto the magnetic part of the transformer. The transformer winding has two annular coaxial coils (1, 2). The coils (1, 2) are mounted between two insulating material end-pieces (3, 4). These end-pieces (3, 4) are held by tie-rods (7) also made of insulating material. The tie-rods (7) fit into holes (10) in the end-pieces (3, 4). At one end of each tie-rod (7) there is a tapered face (9) and at the other end there is a wedge (11). The wedge (11) has serrations which mate with serrations in the tie-rod (7). The tie-rods (7) are made of reinforced resin.
