Casting compositions for producing electrical insulators

摘要

Liquid or pastelike casting composition based on a polymeric matrix resin or on a mixture of such resins for producing self-healing electrical insulators, said casting composition comprising in uniform distribution a selected hydrophobicizing compound or a mixture of such compounds in encapsulated form. The casting composition comprises a thermosettable casting resin system, based preferably on a thermosettable polycondensate, a thermosettable polyadduct, and/or a hybrid form thereof.
