Abstract:
An insulated wire or cable is made by a process comprising the steps of:
(A) extruding onto a covered or uncovered metal conductor or optical fiber a composition having a DF measured at 130° C. (60 Hz, 2 kV) or 120° C. (60 Hz, 8 kV) or 100° C. (60 Hz, 8 kV) of ≤0.5% and comprising:
(1) a high melt strength ethylene-based polymer made in a tubular reactor, and
(2) a peroxide, and
(B) crosslinking the high melt strength ethylene-based polymer.
