Abstract

This work examines the effects of swelling MI type HVDC cable oil on the semiconductive silicone rubber and silicone rubber as used in accessories for application on outdoor termination (EBA) slip on sleeve. The behavior of volume resistivity is monitored as a function of the amount of cable oil diffused into the material. Resistivities of semiconductive silicone samples up to the typical insulator range (${\sim}10^{10}{\Omega}-cm$) are observed as a consequence of swelling due to the presence of the diffused oil. The measured volume resistivities of the oil-impregnated semiconductive silicone rubber are compared to desired value as function of stress relief cone.
