Beschreibung
Zusammenfassung:	The present invention is a method for degassing an electrical cable having a crosslinked, semiconductive shield layer prepared from a composition made from or containing (i) a phase I material consisting essentially of a polr copolymer of ethylene and an unsaturated ester having 4 to 20 carbon atoms, (ii) a phase II material consisting essentially of a nonpolar, low density polyethylene, and (iii) a conducting filler material dispersed in the phase I material and/or the phase II material. The degassing temperature is greater than 70 degrees Celsius.
