Development & Testing New Insulating Compound for HV Dry Cable Accessories & Other Apparatus

Conventional outdoor cable terminations use oil as insulation medium and replacing this with a dry type material has long been a goal of cable accessory manufacturers. Dry type cable accessories offer advantages for both environmental and safety reasons. However, the technical challenge for any newly developed material, apart from high dielectric strength, has been achieving sufficiently good thermal conductivity. This is needed since the effect of thermal dissipation by convection, as offered by liquid insulation, is lost when a dry material is used. This presentation introduces a new dry insulating gel for HV outdoor cable terminations as well as other apparatus and outlines its various benefits.
