Abstract: The present invention is concerned with the curing of coils of a transformer, and particular with improving the curing of coils of a transformer.
A method (100) of manufacturing a coil body of a transformer utilizing UV-curing is provided comprising the steps of providing fibres (202), impregnating the fibres (202) with an UV-curable matrix (203) by an impregnation device (201, 101), forming a tubular coil body of a transformer by using the fibres (202, 102), and curing the UV-curable matrix (203) by exposing the impregnated fibres (202) to UV-radiation (206) emitted from an UV-light source (205, 103).

Abstract: The present invention relates to the shielding of coils of transformers, in particular to a coil for a transformer, a transformer with a coil, and a method of manufacturing a coil for a transformer.
A coil (100) for a transformer with a coil body (102) is provided. The coil body (102) comprises a conductor (201). A first insulation material (203) is attached to the conductor (201). A conductive electric shielding device arrangement (200) is provided for reducing the maximum strength of an electric field generated in the coil (100) or for smoothing the field generated by each coil body (102) of a plurality of coil bodies (102).
