The present invention discloses a geometry electrode in a shed stress con e of a high voltage power cable termination, one end of the geometry electro de being leaded into a conductor of the power cable and the other end being leaded into a composite insulator cladding the conductor, the composite insu lator having a plurality of shed insulators formed of umbrella shape extendi ng outwards, wherein the geometry electrode has a varying curvature radius a long a direction from the conductor of the power cable to the composite insu lator, with the curvature radius increasing gradually towards the composite insulator, and the geometry electrode extends at least to the position above the shed insulator. The present invention also discloses a shed stress cone and a high voltage power cable using the geometry electrode. Using the tech nical solution of the present invention, the same requirements of the electr ical property could be satisfied, and the thickness of the composite insulat or cladding the geometry electrode could be substantially reduced. Such a de sign could reduce the manufacturing cost, lower the difficulty of manufactur ing, and reduce the time for installation.
