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

Abstract: The high-voltage bushing (1) has a conductor (2) and a core (3) surrounding the conductor (2), wherein the core (3) comprises a sheet-like spacer(4), which spacer (4) is impregnated with an electrically insulating matrix material (6). It is characterized in that the spacer (4) has a multitude of holes (9) that are fillable with the matrix material (6). Preferably, the spacer (4) is net-shaped or meshed. It can be a net of fibers. The bushing (1) can be a fine-graded bushing (1) with equalizing plates (5) within the core. As a matrix material (6), a particle-filled resin (6) can be used.

Abstract: The high-voltage bushing (1) has a conductor (2) and a core (3) surrounding the conductor (2), wherein the core (3) comprises a sheet-like spacer(4), which spacer (4) is impregnated with an electrically insulating matrix material (6). The spacer (4) is wound in spiral form around an axis (A), the axis (A) being defined through the shape of the conductor (2). Thus, a multitude of neighbouring layers is formed. The core (3) further comprises equalization elements (5) in appropriate radial distances to the axis (A). It is characterized in that the equalization elements (5) comprise electrically conductive layers (51), which layers (51) have openings (9), through which openings (9) the matrix material (6) can penetrate, and in that the equalization elements (5) are applied to the core (3) separately from the spacer (4). Preferably, the electrically conductive layers (51) are net-shaped, grid-shaped, meshed or perforated. The openings (9) are fillable with the matrix material (6), preferably a particle-filled resin (6) can be used.

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.
