Patent ID: 7981955

Claim:
Electrical high-voltage insulation system, suitable for use as a high-voltage insulation for outdoor use, comprising: a filler material or a mixture of filler materials and optionally further additives, wherein said filler material or said mixture of filler materials has an average grain size, of at least 50% of the grains, in the range of from about 1.0 μm to 200 μm, and is present in an amount of from 5% to 85% by weight, calculated to the total weight of the insulation system, and poly(dicyclopentadiene) as the main component, wherein said electrical insulation system contains at least one hydrophobic compound or a mixture of such compounds comprising flowable fluorinated or chlorinated hydrocarbons which contain —CH 2 — units, —CHF— units, —CF 2 — units, —CF 3 -units, —CHCl— units, —C(Cl) 2 — units, —C(Cl) 3 — units, or mixtures thereof; or a cyclic, linear or branched flowable organopolysiloxane, wherein said hydrophobic compound optionally is present in encapsulated form.
