Study of the electrical properties of HVAC EPDM and HVAC silicone rubber under DC constraint
Résumé
EPDM and Silicone Rubber (SiR) are elastomeric materials used in HVAC cable accessories due to their good mechanical and electrical properties. In this paper one EPDM and one SiR, are tested in DC conductivity and space charge measurements using the pulsed electroacoustic method (PEA) at different electric fields and temperatures. The electrical behaviour of silicone under DC stress is found to be largely governed by space charges while this effect is more limited for EPDM.
