Abstract

A method can include extruding an electrically insulating elastomeric compound about a conductor where the electrically insulating elastomeric compound includes ethylene propylene diene monomer (M-class) rubber (EPDM) and an alkane-based peroxide that generates radicals that form decomposition products; cross-linking the EPDM via radical polymerization to form an electrically insulating layer about the conductor; heating the cross-linked EPDM to at least 55 degrees C. to reduce the concentration of the decomposition products in the electrically insulating layer; and disposing a gas barrier layer about the electrically insulating layer.
