Design of high-voltage cable joints

WHILE there exists a large volume of printed matter on all the aspects of high-voltage cables, the design of the related joints on a theoretically rigorous basis has not hitherto been published in a comprehensive manner. Joints can be classified as the homogeneous case and the heterogeneous case. In the former case the joint and cable insulants are assumed of identical material, whereas in the latter the conditions pertain where the cable insulant is of the usual graded construction and the joint insulant of some different material or dielectric constant.
