摘要： The invention relates to a volume-modified casting compound based on a curable epoxide resin or a mixture of such resins, comprising an epoxide resin, a curing agent, optionally an accelerator and further additives such as fillers, flexibilizers and dyes. Said casting compound contains (a) a three-dimensionally cross-linked polysiloxane in a dispersed form and with a particle size in the range of from 0.02 νm to 50 νm which optionally carries reactive groups capable of chemically reacting with the epoxide resin and/or the curing agent, (b) a selected linear or branched siloxane compound that carries reactive groups capable of chemically reacting with the epoxide resin and/or the curing agent, and optionally (c) a low-molecular oligomeric siloxane compound. The invention further relates to the use of the inventive casting compound as a construction material or as an insulating material, and to the shaped parts and insulations produced therefrom.

摘要： The high-voltage outdoor bushing comprises a conductor (2) extended along an axis (1 ), a condenser core (3) and an electrically insulating polymeric weather protection housing (7) moulded on the condenser core (3). The condenser core (3) contains an electrically insulating tape (4) which is wound in spiral form around the conductor (2), capacitance grading insertions (5) arranged between successive windings of the tape (4) and a cured polymeric insulating matrix embedding the wound tape (4) and the capacitive grading insertions (5). A moisture diffusion barrier is incorporated inside the condenser core (3) prior to moulding the weather protection housing (7). Such a bushing is distinguished by an excellent storage and operation stability under hot and wet weather conditions.

摘要： A bushing with a duct (6) for accommodating a conductor rod which is surrounded by an electrical field grading insulation (5) comprises a core (1) with a cylindrical shell (2) encapsulating the grading insulation (5) and a f lange (3) surrounding the said shell (2) and carrying through holes (8) distributed over its circumference for allowing the bushing to be attached to a wall (4) by bolts (12). The shell (2) and the flange (3) are in one piece and consist of an insulating matrix material, e.g., a plastic material mixed with an anorganic filier material. The through holes (8) are surrounded by essentially ring-shaped metal inserts (9) each forming an annular surface flush with the surface of the flange (3) which is in contact with the head of the bolt (12) and takes up the force exerted by the latter on the flange (3). A test tap (13) comprises a contact pin (14) which is electrically conductively connected to the outermost layer of the grading insulation (5) and surrounded by a contact ring (15) connected to every second metal insert (9) by connection wires (17) for grounding the contact pin (14) via the contact ring (15) when the test tap (13) is not in use and covered by a metal cap. The core (1) is produced by filling a mould with the liquid matrix material after components of the grading insulation (5) and other parts have been fixed in the same.

摘要： Mold-free resin-insulated coil windings are obtained by applying continuous fibers (4) embedded in a quasi-solid-state epoxy-resin matrix, e.g. in the form of a tape (2; 2a, 2b), to the coil windings (3). The tape (2; 2a, 2b) is locally heated up to the melting point of its polymer matrix, and is subsequently pressed against the winding body (1). The heated and fused resin of the tape (2; 2a, 2b), which is pressed onto the coil (1), flows under pressure into the voids and gaps between the coil windings (3) and fills them up, thereby hermetically insulating the coil windings (3). After leaving the heating and pressing apparatus (7, 5) the fused epoxy resin becomes solid again. The resulting curing process is thus considerably simplified and shortened, compared to the state of the art.
