Owing to its simple structure, easyinstallation and low cost, bolt-type power connector-parallel groove clamp is widely used inoverhead power transmission and distribution line. However, owing to high current load and harshenvironment in China, there are still some problems in application of this kind of connector. So,some failure connectors replaced from domestic overhead power lines are collected. The main reasonsthe failure are given out through investigation into residual contact force, connection resistance,substrate quality, makeup, condition of contact interface and installation, manufacture techniqueetc. Then, the current test on parallel groove clamps is carried out and finite element method isused to simulate its failure process.展开更多
