Dieses Verfahren setzt jedoch besondere Maßnahmen voraus, um eine homogene Verteilung des Be* chleunigerzusatzes in Glimmerbinaemittel au gewährleisten. Ferner ist bei der Vervendung von Beschleunigern auf Basis tertiärer Ab ine eine Einwirkung auf das Bindemittel im 3irx>e einer Hartungsreaition vor allem bei Lagerung bei erhöhter Bausttemperatur νη& über längere Zeiträume nicht mit Sicherheit auss.v schließen.

However, this process requires special measures to ensure a homogeneous distribution of the accelerator additive in the mica binder. Furthermore, when using accelerators based on tertiary ab ine, an effect on the binder in the 3irx> e of a hardening reaction cannot be ruled out with certainty , especially when stored at elevated building temperatures νη & over long periods of time. The gel renamed application of binding agent and sluice.?. Hunting on the mica tape also requires further refinements2 using solvents, which must be evaporated from the isolated egg again. A problem-free removal of the insulation tape, however, encounters greater difficulties. Since even small proportions of the solvent are known to have a considerable negative impact on the dielectric properties of Eocä »voltage isolators, such difficulties can be taken into account.
Es wurde nun gefuzden, daß diese Schwierigkeiten behoben vrs^d können, wenn als lindemittel im Glimmerband sur Herstellimg dor Wicklung ein Harz verwendet wird, welches funktionell© Gruppen aufweist, die eine beschleunigende Wirkung auf die Umsetzung d€c Epo3grdkomponente ces !Kränkmittels mit der Vernetzungsäiompozi^nte ausübene Pur diesen Zweck eignen sich insbesondere Polyeporzydverbindungen, die eine Stickst off gruppierung, insbesondere AmIrstickstoff gruppen, im Molekül enthalten.
