  • Relief of an Electric Field via a Cone Structure

    edge. A structure of cone type is a major method to alter the lines of equi potential and to relieve the electric stress around the ground. The dimensions of the cone depend on the cable structure. In this paper we introduce a way to calculate the displacement of equipotential lines when a cone is brought into a coaxial cable, RG220, and then

  • Shielding Of Power Cables

    As well, leakage current and capacitive current through the insulation presents a danger of electrical shock. The grounded shield equalizes electrical stress around the conductor, diverts any leakage current to ground. Be sure to apply stress relief/ cones at the shield ends, especially for cables operating at more than 2Kv to earth.

  • What Is Electrical Stress?

     · Electrical Stress Explained. Without an insulation shield, you can see how the voltage leaves the conductor travelling through the insulation, very erratically and effectively seeking ground/earth, creating hot spots and eventually cable failures – basically this is electrical stress.

  • Stress cones | Mike Holt's Forum

     · You have electrical energy coming down the pipe (wire) and if you just cut off the insulation, it will tend to blast right out the end. You need a stress cone to bring it to a subtle stop. Consider that the first layer of the insulation on the high voltage cable is semiconducting, so you need fitting on the end (the stress cone) that mimmics the conductor's insulation.
