1. A semiconductive composite material consisting essentially of (A) a polar ethylene-based copolymer and an electrical conducting effective amount of (B) an ultra-low-wettability carbon black (ULW-CB), which has a Brunauer-Emmett-Teller (BET) nitrogen surface area of from 35 to 190 square meters per gram (m2/g), measured by BET Nitrogen Surface Area Test Method; and an oil absorption number (OAN) from 115 to 180 milliliters of oil per 100 grams (mL/100 g), measured by Oil Absorption Number Test Method; and a water uptake of from 400 to 700 parts per million (ppm, weight), measured by Moisture Uptake Test Method;
wherein the (A) polar ethylene-based copolymer is from 66 to 81 wt % of the total weight of the semiconductive composite material;
wherein the (B) ULW-CB is from 19 to 34 wt % of the total weight of the semiconductive composite material.
