Abstract: A wide band high frequency compatible electrical coaxial cable is provided with an outer conductor, a dielectric, and an inner conductor that is arranged about a plastic core and includes an inner layer of film that is surrounded by and in electrical contact with a plurality of twisted round conductors. A pressurized cooling fluid is circulated within the plastic core for high load applications such as supplying power to a laser.

Abstract: A cable bushing which provides for an electromagnetically tight guidance of a shielded electrical cable, the jacket of which has been stripped from the shield in the bushing area, and the cable led through an opening in a partition, wherein electrically conductive part shells are mounted to the exposed part of the cable shield and an electrically conductive sleeve is slipped over the part shells. The sleeve is provided with a cover disk, which forms an integral part of the sleeve, with an annular disk which can be radially attached to the sleeve and incorporates a radial slot, with a threaded nut which can be screwed to the sleeve and with a counter-nut acting on the threaded nut. With the exception of the cover disk and the ring disk, all components of the cable bushing have smaller outer dimensions than the inner dimensions of the partition opening. In this way the cable bushing can be preassembled with a cable assembly before being mounted to the partition.
