Abstract

The study addresses the treeing-performance of unsaturated polyester resins with and without silica nanofillers and epoxy resin. Specimens with embedded needles mounted on a grounded plate are used. Time to electrical tree initiation, time to breakdown and growth behavior are determined. The influence of filler loading on the treeing performance as well as the effect of voltage amplitude are investigated. The results show that the resistance to treeing strongly depends on the type of matrix material used. While 1 wt. % nanofiller leads to improved resistance to electrical treeing, 5 wt. % worsens the treeing performance.
