Abstract: Processes for making cables and cable cores having a crosslinked insulation layer. The processes comprise (a) providing an initial cable core having a conductor, a first semiconductive layer, an initial insulation layer comprising a crosslinkable polymeric composition, and a second semiconductive layer, and (b) subjecting the initial cable core to a crosslinking process. The crosslinkable polymeric composition comprises an ethylene-based polymer, an organic peroxide, and a polyallyl crosslinking coagent. The polyallyl crosslinking coagent and the organic peroxide are present in amounts sufficient to provide an allyl-to-active oxygen molar ratio of less than 1.2.
