CONNECTION STRUCTURE CABLE TERMINATION ELECTRICAL APPARATUS

摘要

PROBLEM TO BE SOLVED: To obtain a superior performance by making mutually exclusive characteristics of improvement of breakdown voltage characteristic and downsizing and weight reduction compatible in a connection structure between cable connection part and an electrical apparatus. SOLUTION: The cable termination structure has a feature in that an electrical field application part of the outer face of a bushing has an arcuate shape in its profile vertical cross-sectional form. A ground electrode is placed near the outer face of the bushing. Because both on the surface of the bushing and at the boundary between the stresscone and the bushing the property can be improved, the high breakdown voltage property can be obtained.
