INSILCOTE is a unique Room Temperature Vulcanised, (RTV) silicone rubber formulation, specifically developed by Mace Technologies, South Africa, in collaboration with the Electric Power Research Group of the University of the Witwatersrand for the prevention of pollution flashover of high voltage outdoor insulation.
The exceptional hydrophobicity of INSILCOTE inhibits the formation of continuous moist conductive layers on insulator surfaces. This, in turn, limits the flow of leakage currents, thus preventing the creation of dry bands and partial discharges – critical steps in the flashover process.
