Abstract (en)
An impregnation compound for electrical cables, especially for high voltage DC power cables, with an insulation of a plurality of permeable tapes, has a high nearly constant viscosity of 200 - 700 Pas up to an operating cable conductor temperature of at least 40 DEG C and low viscosity of less than 0.1 Pas in a temperature range of about 75 DEG to 130 DEG C. The compound consists of 80-98wt% of a mineral oil, 1-10wt% of a thermoplastic elastomer and 1-10wt% of a gas absorbing agent, especially dibenzyltoluene.
