Abstract

Results are presented concerning the characterization of both electrical properties (volume resistivity, permittivity, tan δ) and mechanical properties (mass density, tensile strength, elongation, etc.) of cross-linked polyolefin stress control tubes (SCT). The authors also examine the chemical compatibility of such materials with the impregnation oil used in paper impregnated cables; results concerning the above properties obtained after an accelerated aging test in oil at 100°C, according to ASTM D471/2, are reported. In order to correlate the behavior of materials with that of components, partial discharge characteristics and impulse withstand voltages for extruded cable terminations manufactured with unaged and 4-th oil aged SCT are compared
