1. A coated conductor comprising a conductive core and an insulation layer at least partially covering the conductive core, wherein at least a portion of the insulation layer comprises a crosslinkable polyolefin formulation comprising (A) a polyethylene polymer and (B) an arylketone of formula (1a-3):

OG Complex Work Unit Chemistry
wherein R7 is an unsubstituted (C1-C5)alkyl group or an unsubstituted (C6-C40)alkyl group; wherein the (A) polyethylene polymer comprises from 51 to 100 weight percent (wt %) ethylene-derived constituent units and from 49 to 0 wt %, respectively, of alpha-olefin-derived constituent units, based on weight of the (A) polyethylene polymer; and wherein the crosslinkable polyolefin formulation comprises from 30.0 to 99.9 wt % of the (A) polyethylene polymer based on total weight of the crosslinkable polyolefin formulation and from 0.1 to 3.0 wt % of the (B) arylketone based on total weight of the crosslinkable polyolefin formulation.
