Abstract: The present invention relates to a telescopic sliding beam for supporting a work machine comprising a sliding beam box and an internal sliding beam that is outwardly telescopically supported in the sliding beam box. The sliding beam box and the internal sliding beam have an opening in the peripheral region, with the openings overlapping one another in an outwardly telescoped state, and with a bolt being able to be introduced into the overlapping openings. The sliding beam box has an abutment at its inner side and the internal sliding beam has an abutment at its outer side, with the abutment of the sliding beam box and the abutment of the internal sliding beam contacting one another in an outwardly telescoped state such that a further pulling of the internal sliding beam out of the sliding beam box is suppressed. The invention furthermore comprises a work machine comprising this telescopic sliding beam.

Abstract: The invention relates to electric insulation with a polyolefin base for medium and high voltage from about 10 kV up. In insulation of this type the formation of so-called water trees is to be prevented on the one hand and on the other hand, the dielectric losses are to be kept as low as possible. For this purpose it is provided that silicic acid prepared in the following manner is added to the insulation: SiO.sub.2 -containing mineral substances are melted with additions of aluminum oxide, boron oxide and carbonates and/or oxides of alkali and earth-alkali metals to form a homogeneous glass phase; from the glass melt, glass bodies with a large surface are made; the glass bodies are subjected to a leaching process with mineral acid; the porous SiO.sub.2 bodies produced are washed and dried and optionally milled. The electric insulation according to the invention is particularly well suited for use in cables and wires.

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.
