Abstract	Supersmooth (SS), extra-clean semiconductor shields have been demonstrated to be markedly improved in extruded surface smoothness and to contain a minimal level of ionic impurities. In well-accepted accelerated cable aging tests for wet locations, where the SS extra-clean semiconductives are used as conductor shields, substantial improvements in cable performance have been demonstrated. Additional studies have shown that the SS extra-clean shields initiate far fewer vented water trees in the associated insulation. Both the SS ethylene ethyl acrylate (EEA) and SS ethylene vinyl acetate (EVA) products demonstrate these improved properties. When these superior semiconductives are combined with tree-retardant cross-linked polyethylene (TR-XLPE) insulation, the very best cable performance properties were obtained. It is concluded that, for cables that will be subjected to wet service conditions, the use of SS extra-clean conductor shields combined with TR-XLPE insulation will offer high-quality, cost-effective long-life cable construction.<>
