Summary
Read more on ELECTRAHVAC and HVDC cable systems consist of cables and accessories such as joints and terminations. At every cable end, the uniform radial electrical field of the cable is distorted and must be controlled by the accessories. Thus, interfaces between the cable and the accessory are created that are critical for the cable system stability. This Technical Brochure discusses interface compatibility and describes the interface parameters, formalizes failure modes, summarizes development tests and proposes considerations related to qualification testing.
