    Abstract: 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.

    Abstract: A volume modified epoxy resin casting composition comprises a three-dimensional cross-linked polysiloxane in dispersed form having a particle size of 0.02-50 mu m that may react with the epoxy resin and/or the curing agent and a linear or branched siloxane compound having reactive groups that may react with the epoxy resin and/or hardener. A volume modified casting composition (I) based on a curable epoxy resin comprising an epoxy resin, curing agent, optionally an accelerator and other additives such as filler, flexibilizing agents and coloring agents is characterized in that the composition (I) comprises (A) a three-dimensional cross-linked polysiloxane in dispersed form having a particle size of 0.02-50 mu m that may react with the epoxy resin and/or the curing agent, (B) a linear or branched siloxane compound having reactive groups that may react with the epoxy resin and/or hardener and optionally (C) a low mol. wt. oligomeric siloxane compound. An Independent claim is included for a process for the production of the composition (I) such that at least a portion of the epoxy group containing components (A) and (B) are pre-mixed and pre-hardened or at least a portion of the hydroxyl, amine or carboxyl containing components (A) and (B) are pre-mixed with the epoxy resin and pre-hardened.

    Abstract: The invention relates to a volume-modified casting compound based on a curab le epoxide resin or a mixture of such resins, comprising an epoxide resin, a curing agent, optionally an accelerator and further additives such as filler s, 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 .mu.m to 50 .mu.m which optionally carries reactive groups capable of chemically reacting with the epoxide resi n 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, an d to the shaped parts and insulations produced therefrom.
