1. A wire or cable comprising:
a metal conductor or an optical fiber;
an insulation sheath extruded onto the metal conductor or optical fiber, the insulation sheath comprising a crosslinked composition polymer having gel content of greater than 30% and composed of
an ethylene-based polymer modified with at least one of poly(propylene glycol) allyl ether methacrylate (PPG AEMA), a chain transfer agent, or an asymmetrical polyene, wherein
(A) the crosslinked composition has a dissipation factor (DF) measured at 130° C. (60 Hz, 2 kV) of less than or equal to (≤)0.5%; and
(B) the ethylene-based polymer prior to crosslinking satisfies the following equation at a test temperature of 190° C.
Melt Strength=Ce−0.3(melt index with 2.16 kg load)
where the parameter C is greater than or equal to (>) 15.
