A study on analysis of interfacial breakdown properties with variable temperalure in straight cable Joint modeling EPGXY/EPOM interface

온도에 따른 케이블 직선 접속재 모델링 EPOXY/EPDM 계면의 파괴 특성에 관한 연구

In power cable joints, the interfaces of two different dielectric materials are inevitable. In addition, the interfacial breakdown between two internal dielectric surfaces represents one of the major causes of failure for power cable joints. We chose epoxy/EPDM interface, one of the interface in cable joints, and investigate dielectric interfacial breakdown phenomenon. First, design specimen with Flux 2D. Second, find interface condition which has high dielectric strength. Third, investigate interfacial breakdown properties with variable temperature.
