Abstract

By using an electrically conductive PTFE fabric, high-voltage insulation systems are simplified and can be made thinner, also improving the thermal conductivity. The insulation material is in two layers, each with a hydrophobic and a hydrophobic region, and the hydrophobic regions of the layers are opposed.
