Where should a stress cone be used?

A stress cone is specifically designed for high voltage terminations, where it provides essential stress relief to the electrical insulation and conductor. In high voltage systems, electric fields can become excessively concentrated, leading to insulation breakdown if not properly managed. Stress cones help distribute this electrical stress over a larger area, preventing potential failures and enhancing the longevity and reliability of the electrical system.

The design of the stress cone allows it to create a smooth transition between the conductor and insulation, which is critical for ensuring that there are no sharp edges or points that could lead to electrical discharges. Using stress cones in high voltage terminations is a standard practice in the industry, as it contributes to safe operation and maintenance of electrical systems while minimizing the risks associated with high voltage applications.

Other options, such as low voltage junctions, grounding connections, or neutral connections, typically do not require the same level of protection and stress management that high voltage terminations do, making them less appropriate for the use of a stress cone.
