Filled and unfilled EPDM rubbers were contaminated with two different particle sizes (50 /spl mu/m and 165 /spl mu/m) and different particle concentrations, to ascertain their influence on the breakdown strength. The inclusions were irregularly shaped iron particles. The breakdown tests were carried out by using /spl sim/0.7 mm thick circular rubber slabs between cylindrical electrodes. The result yielded the characteristic AC breakdown strengths of 78 kV/mm and 86 kV/mm respectively for non-contaminated filled and unfilled rubbers. The electric strength was considerably lowered for larger inclusions but not in the case of smaller ones. A statistical evaluation of the results is also provided.","PeriodicalId":13148,"journal":{"name":"ICSD'98.

Then they were evaluated in the laboratory. The field test was conducted in an environment of light coastal pollution where the materials were non-energized as well as energized with both HVAC and HVDC. The long-term study focused on the hydrophobicity and the material changes of the insulator surfaces combined with the leakage current performance of the insulators. In general, the results presented in this paper show that the surface ageing of the two types of silicone rubbers was relatively moderate and that both the non-energized and energized materials remained highly water repellent. Moreover, no substantial differences in the hydrophobicity between the two material types were observed after almost nine-years in the field. However, the leakage currents of the insulators differed. This indicates that the hydrophobicity, as it is usually measured, is not a good indicator of the surface resistance of the insulator material.","PeriodicalId":13148,"journal":{"name":"ICSD'98.
