Abstract
An effective seal between the suspension mounting and the glass fiber rod of a compound high voltage insulator is obtained by filling the gap with a mixture of cross-linkable monomers or polymers formed from two or more reactive components, the mixture having a viscosity prior to cross-linking of less than 100,000 mPa.s and a penetration value between 1-500 mm/10 after cross linking. Particularly suitable are polymers based on polyorganodimethylsiloxanes.
