Abstract
A core-form transformer winding with liquid coolant flow diversion bands is disclosed. The apparatus includes a winding tube with a central longitudinal axis. A number of coil sections are axially displaced along the central longitudinal axis of the winding tube. Radial ducts are formed between the coil sections. Internal vertical ducts are formed within each of the coil sections. A liquid coolant is used to cool the windings during operation. Flow diversion bands are placed around every other coil section. The flow diversion bands generate a partial blockage of the liquid coolant, which produces a radial flow into one or more of the radial ducts, resulting in vertical flow through the internal vertical ducts.
