Abstract: The stock contains an insulating-material matrix and a filler embedded in the matrix and is distinguished by a cellular structure. The predominant portion of the cells is filled with a material having arc-extinguishing properties or contains a material which, on exposure to an arc, forms arc-extinguishing gas. For the purpose of improving the making and breaking capacity, such a stock can advantageously be employed in a gas-blast circuit breaker in which arcextinguishing gas is blown onto the switching arc (11). This involves the stock preferably being positioned at such points guiding the arc-extinguishing gas, at which the stock is exposed to the radiation of the arc (11) and the thermal action of arc gases.

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: This high-voltage installation has a metallic housing (1, 5) which is filled with insulating gas and surrounds voltage-carrying active parts (3, 7). It is provided with insulators for the electrically insulating support of the active parts (3, 7) in the housing (1, 5), with drive means formed in an electrically insulating manner for the actuation of the mobile sections of the active parts and with at least one protective coating (11) which covers at least the insulators and the drive means formed in an electrically insulating manner. It is intended to provide a high-voltage installation having a protective layer which is impermeable to liberated chemically aggressive decomposition products, in particular hydrofluoric acid, during the entire service life of the installation. This is achieved by the protective coating (11) being formed in such a way that decomposition products formed in the insulating gas during operation of the installation penetrate into the protective coating (11), and by the protective coating (11) having at least one component which reacts with the decomposition products to form at least one solid, nonhygroscopic reaction product. The reaction product produced by the reaction remains thereafter in the protective coating (11).
