ABSTRACT:
An electrical inductive apparatus, for example a transformer or a reactor, comprises a core and at least one winding wound around the core and formed of a plurality of superimposed turns of sheet-formed electrically-conducting material. The winding includes at least one element which, together with a surface of at least one of the turns of the winding, defines a plurality of channels for conducting an electrically-insulating fluid in contact with a part of said surface. These channels are defined between adjacent pairs of a plurality of connected together elongated spacing means of the element which are arranged in substantially parallel spaced relationship and which contact said surface. Each spacing means has a thickness which increases from a central region of the spacing means towards each of its opposite ends. This enables the turns of the winding to be flared out at their opposite ends in a suitable manner with respect to the electrical properties of the winding. The element may be manufactured from a sheet of insulating material by profile sawing in a processor-controlled sawing machine.
