Abstract :
In this paper the first results concerning the characterization of filled elastomers used for stress control are reported. In particular, two types of cold shrink stress control tubes (SCTs) have been considered: one is based on EPDM and the other on silicon rubber. Their electrical properties are compared over a wide range of applied electrical, mechanical and thermal stresses
