    Abstract: The present invention relates to a device for terminating cables (1), particularly for underwater termination of high voltage power cable and for conducting high voltage conductors in an electrical underwater apparatus, with the purpose of providing a liquid and water tight termination, at the same time as it provides pressure relief for vital components. According to this it is suggested that: each high voltage conductor (phase) (2a, 2b, 2c) is terminated in a separate, liquid filled and pressure compensated interior chamber (7a, 7b, 7c); conduction of the high voltage conductor from each interior chamber into attached electrical apparatus is carried out by means of a solid electrical conductor (10a, 10b, 10c), said conductor being fixed in an insulation material (11) which is liquid and gas tight, the solid electrical conductor and insulation material forming a gas and liquid tight barrier between the cable conductor and attached apparatus, and all interior chambers (7a, 7b, 7c) are adapted to a common, liquid filled and pressure compensated outer chamber (4).

    Abstract: The invention relates to a nonlinear field control tape containing ZnO microvaristor particles. The doped ZnO particles are produced by crushing a sintered ZnO block, by desagglomeration or crushing of calcinated granulated particles, or by crushing of a calcined or sintered tape (tape casting). Embodiments, among other things, relate to: hollow ZnO microvaristor particles produced by granulation technique, having reduced average density and having diameters in a range well below 90 µm; and compounding the ZnO filler in binders that are used to impregnate tapes. Compared to nonlinear field control tapes with conventional embedded nonlinear filler particles, a stronger and more reliable nonlinear resistivity is achieved and the ZnO filler is simpler to produce and to compound in the binder. The resulting tapes are flexible, preferably self-adhesive and have a strong nonlinear electrical resistivity. The tapes are useful to protect high field-stress regions in electrical components.

    Abstract: The bushing has an electrical conductor (1) to which high voltage can be applied. One section of the electrical conductor (1) is surrounded by a varistor arrangement (9). The bushing also contains two electrical connections (4, 6), one (6) of which can be connected to high voltage and the other (4) can be connected to ground, a bushing insulator (5) provided between the electrical conductor (1) and the varistor arrangement (9), and a clamping apparatus (11) which applies a contact force to the electrical connections (4, 6) and to the varistor arrangement (9) located in between them like a sandwich. The clamping apparatus has an insulating part which applies the contact force to the two electrical connections. The bushing insulator is in the form of a molding and has a supporting element, provided with a guide surface, for a contact (1a) (which is connected to the electrical conductor (1)) in a plug connection to a cable or to an apparatus bushing of an electrical apparatus.
