A further advantage of perfect layer winding is heat conduction. Generally scramble wound coils due to their poor heat conduction will be hotter nearer the centre, with detrimental effects upon wire insulation. It has been shown that no perceptible difference occurs between the inside and ouside of an orthocyclically wound coil. As mentioned there are certain circumstances where orthocyclic winding is not possible, paper interleaving for example, where this is the case we can perform these winding tasks also.
