Abstract
A power cable comprising: (A) a conductor, (B) an insulation layer, and (C) a semiconductor layer comprising in weight percent based on the weight of the semiconductor layer: (1) 49-98% of a crosslinked olefin block copolymer (OBC) having a density less than (<) 0.9 grams per cubic centimeter (g/cm), a melt index greater than (>) 1, and comprising in weight percent based on the weight of the OBC: (a) 35-80% soft segment that comprises 5-50 mole percent (mol %) of units derived from a monomer comprising 3 to 30 carbon atoms; and (b) 20-65% hard segment that comprises 0.2-3.5 mol % of units derived from a monomer comprising 3 to 30 carbon atoms; (2) 2-51% conductive filler, the insulation layer and semiconductor layer in contact with one another, is degassed by a process comprising the step of exposing the cable to a temperature of at least 80° C. for a period of time of at least 24 hours.
