Silicone Gel Compounds for Non-Linear Stress Grading Applications
Keyword(s):
The paper deals with a field-grading insulation usingsilicone gel as main material/binder. Additives, which providethe nonlinearity of the compounds, consist of a support materialwith metal oxide coating. The nonlinear electrical propertieswere adjusted by the addition of different dopants. In thisinvestigation the fundamental properties of new non-linearconductivematerials (NLCM) were examined. One aim of theinvestigation is to attribute the macroscopic electrical behaviorto the respective doping. For a typical compound, fieldcalculations for a cable joint model are presented and comparedto a conventional design without NLCM.
