1. A cable insulation having high resistance to the formation or growth of water trees and high aging resistance and consisting of a low polyethylene (I) and from 0.5 to 20% by weight, based on the low density polyethylene (I), of an ethylene polymer (II) which differs from (I) and conventional additives in the usual amounts, wherein the ethylene polymer (II) is an ethylene terpolymer having a melt flow index of from 1.0 to 30 g/10 min, measured at 190 degrees C and under a load of 2.16 kp according to DIN 53.735, and consisting of a) 100 mole parts of copolymerized ethylene b) from 1 to 5.5 mole parts of a copolymerized C1 -C8 -alkyl ester of a C3 -C6 -alkenecarboxylic acid and c) from 1 to 3.2 mole parts of a copolymerized C3 -C6 -alkenecarboxylic acid. |
