Electric article comprising at least one element made from a semiconductive polymeric material and semiconductive polymeric composition
Abstract:
An electric article, particularly an electric cable or an accessory thereof, such as a cable joint or a cable termination, includes at least one element made from a semiconductive polymeric material, wherein the at least one element is obtained by crosslinking a semiconductive polymeric composition including: (a) at least one elastomeric polymer; (b) a filler mixture including: (i) at least one first carbon black having a dibutyl phthalate (DBP) absorption number of from 250 to 600 ml/100 g; (ii) at least one second carbon black, different from the first one, having a dibutyl phthalate (DBP) absorption number of from 80 to 250 ml/100 g; and (c) at least one graphite having a specific surface area, measured according to the BET method, not higher than 20 m2/g.
