Patent ID: 7750080

Claim:
A power cable coating compound consisting of: a) an elastomeric component consisting of: 1) an ethylene alpha-olefin vinyl norbornene elastomeric terpolymer; and 2) an ethylene alpha-olefin copolymer having a Melt Index Ratio of I 10 /I 2 of a least 7, wherein the ethylene alpha-olefin copolymer comprises a copolymer of ethylene and 1-octene, wherein the ethylene alpha-olefin copolymer is present in the coating compound in an amount greater than 50 percent by weight, based on the weight of the ethylene alpha-olefin vinyl norbornene elastomeric terpolymer and the ethylene alpha-olefin copolymer, and wherein the coating compound has a 14-day dissipation factor (600V, 60 Hz, 90° C. water) of less than or equal to about 0.0049; and b) one or more fillers or additives selected from the group consisting of a clay, vinyl silane, lead, antioxidant, low density polypropylene, wax, zinc oxide, peroxide, and combinations thereof.
