A Study on Electric Conduction Characteristic in the Glass Transition Point of electric Power Equipments Cross - Linked Polyethylene

전력설비용 가교 Polyethlene의 Glass 전이점에서의 전기전도 특성에 관한 연구

It happened that there was a sudden peak with the capacity of change, when I measured the capacity of change, cubical expansion and Thermally Stimulated Current on the Cross - Linked Polythylene. Crystal melting began at 375 K and changed into formaless shapeless at 380 K. The conduct of a particle on the surfase of dipole, electron trap was founded to be ion conduction nature under the low electronic field, wherase, the electron nature under the high electronic field. Consequentity, under the semi-conduction layer electronic a particle was injected to inter-fase and accumulated for a time and appeared to be TSC.
