Abstract

The winding is made-up of an electrically conductive strip which is wound with an insulating strip onto the outside of a tube into which may be placed a ferrite core. The conductive strip (1) is a thin sheet of aluminium. The insulating strip (2) is either a layer of plastic material or a layer of the oxide of the conductive strip material. The conductive material may be deposited onto the plastic strip. The width of the conductive layer is related to the number of layers such as to decrease the risk of electric arc formation between the outside layers and the edges of the ferrite core. This type of construction of a transformer provides a large surface area with respect to its cross-section.
