ABSTRACT:
In an electric high voltage cable of 1-500 kV, the cable insulation is resistant to the formulation or the growth of water trees and consists of from 70 to 99 parts by weight of an ethylene polymer (I) and from 1 to 30 parts by weight of an ethylene copolymer (II) which is composed of from 80 to 92% by weight of ethylene and from 8 to 20% by weight of a C.sub.4 -C.sub.10 -.alpha.-olefin having a density of from 0.890 to 0.915 g/cm.sup.3 and a crystallite melting point of from 90.degree. to 125.degree. C.
