An electrically conductive and semiconductive device utilizing polymers having resistance to water treeing and good dielectric properties as well as other improved properties. The polymer comprises ethylene polymerized with at least one C3? to C20? alpha-olefin and optionally at least one C3? to C20? polyene. The polymer utilized has a density in the range of about 0.86 g/cm?3 to about 0.96 g/cm?3, a melt index in the range of about 0.2 dg/min to about 100 dg/min, a molecular weight distribution in the range of about 1.5 to about 30, and a composition distribution breadth index greater than about 45 percent. For the polymer utilized, the tree rating is generally less than 40, the power factor is in the range of 0.0002 to 0.0005, and the dielectric constant is in the range of 1.8 to 2.4. |
