A brief review of the theory of paper lapping of a single-core high-voltage cable

A brief outline of the theory of the lapping operation for high-voltage single-core paper-lapped cable is given, showing the stability conditions which the insulation thickness must satisfy in order that bending of the cable on the reel or capstan does not cause any damage to the insulation itself. An example of the design of a high-voltage cable is considered, showing the application of the theory outlined and its practical use.
