Abstract
A device is disclosed with an internal conductor, which is arranged within the tube interior of a tubular metal sheath and is electrically insulated from this sheath with a compacted, electrically insulating material, in which the compacted electrically insulating material is a compacted magnesium oxide granulate made from magnesium oxide grains of different sizes with edges and projections, and that sections, especially edges and projections of magnesium oxide grains are pressed, under local deformation of the internal conductor and/or the tubular metal sheath, into the internal conductor or into the tubular metal sheath. A method for manufacturing such a device is also disclosed.
