In cable termination and joints, insulation tape (or rubber plastic prefabricated components) is wound from the edge of the metal sheath to form a transitional cone between the edge of the metal sheath and the outer surface of the increased insulation, which is called a stress cone (in design, the axial field strength of the cone should be a constant).

The function of a stress cone is to improve the electric field distribution at the end of the metal sheath and reduce the electric field strength at the edge of the metal sheath. The following is a simple principle by which a stress cone can play this role.

The shape of the stress cone is designed based on its surface axial field strength being equal to or less than the maximum allowable axial field strength
