A COMPREHENSIVE PROGRAMME FOR THE EVALUATION OF ESSENTIAL MATERIAL PROPERTIES OF SILICONE RUBBER FOR OUTDOOR HIGH VOLTAGE APPLICATIONS

, , , , , and . (1997)

Abstract

The papers deals with the scientific background and selected results of Cellpack's Silicone Rubber (SR) Programme, which was started in late 1994. The necessity for establishment of the programme is briefly discussed. From the investigated material properties, in this contribution the results are presented, which focus on the hydrophobicity of the SR-surfaces. To evaluate this essential property, there are no standards available yet. For this reason, accelerating ageing procedures using either simultaneous voltage and moisture stresses or UV-radiation are applied to investigate the hydrophobicity resistance. The transfer of hydrophobicity is measured by a layer penetration test. These results are related to the results gained by the salt fog procedure for composite insulators, which is described in IEC 1462 Draft and Type II Report.
