The first silicone cable accessories were developed in the late 1960ies. They appeared together with the first extruded XLPE-cables. Focus of the engineers at this time was a design with field-grading and insulating parts in a prefabricated body that allowed easy assembling and avoiding mounting errors. The first parts of both, terminations and joints were still rather massive as the outstanding electrical behavior of silicone was not yet fully understood but test results and first service experiences in comparison to the - at this time state-of-the-art - polyurethane and other alternative solutions were found encouraging. Thus, the main idea of a prefabricated, silicone-elastomeric body remained and was further refined since. Today - having gained more and long-term experiences of the rather unique combination of properties of silicone elastomers - customers enjoy availability of a wide portfolio of all types of silicone elastomers and auxiliary silicone materials for medium- and high-voltage cable accessories. The paper deals with some important aspects of the subject in an overview.
