ELEKTRISCHE ISOLIERUNGEN

摘要

The invention relates to electrical insulation material of a polyolefin composition with a phosphate additive which prevents the formation of so-called water trees. The phosphate additive may be a water-soluble alkali or earth-alkali phosphate and/or a hydrolysable phosphoric acid ester (RO)3PO, wherein at least one of the substituents R is an aliphatic radical and the remaining substituents may be hydrogen or an aliphatic radical. The electrical insulation according to the invention is suited particularly for use in cables and wires.
