ABSTRACT:
Insulation particularly suitable for high voltage power cable consists essentially of low density polyethylene (or crosslinked polyethylene) and an effective amount of an alcohol of 6 to 24 carbon atoms which is a tree growth inhibitor capable of imparting at least a thousand-fold increase in electrical endurance as measured by an accelerated test procedure. Electrical trees can be initiated in the polyethylene in the presence of the alcohol. However, increased electrical endurance is obtained through inhibition of continued tree growth at that site.
