Abstract: The invention relates to an electrical insulation composition of a polyolefin, which can be used for medium and high voltage from about 10 kV and which resists effectively and permanently the formation of so-called water trees. The insulative polyolefin contains an inorganic oxide additive, in homogeneous distribution therewith, at a concentration of 0.05 to 10% by weight, relative to the total weight of the composition. The additive is absorption-active for heavy metal ions and/or binds heavy metal ions in an ion exchange, with a particle size of up to 50 um or an agglomerate size of up to 100 um. It can be silica, alumina, hydrated alumina or an aluminum silicate. The electrical insulation according to the invention is particularly well-suited for use in cables and wires.
