An impregnating resin, e.g., a catalytically hardenable impregnating resin for the conductor of an electrical machine, may include at least one reactive resin mixed with at least one reactive diluent and a hardening catalyst, e.g., for cationic, anionic or coordinate polymerization of the impregnating resin. The properties of the impregnating resin or use thereof may be improved by virtue of the reactive diluent containing a heterocyclic four-membered ring. The impregnating resin may be part of a main insulation of a conductor arrangement, which may in turn be installed in an electrical coil or other electrical machine.

Impregnating resin, conductor arrangement, electrical coil and electrical machine

Tape adhesives suitable for impregnating processes for insulation systems are described. Embodiments of the tape adhesives include solid insulation material such as mica, anhydride-free impregnating resins and accelerators for the anhydride-free impregnating resins. The tape adhesives may be adjusted with respect to the reactivity of the accelerators for the anhydride-free impregnating resins in relation for the storage stability of the overall insulation systems.

Tape adhesive for an insulating tape in an insulation system and an insulation system

The present disclosure relates to electrical machines. The teachings thereof may be embodied in insulation systems for electrical machines, more particularly in the high-voltage range, for example, in an insulation system for electrical machines including: an insulator comprising a porous insulating material; an impregnator comprising a catalytically or thermally curable resin material having oxirane functionalities, or a mixture of different reactive resin materials having oxirane functionalities; and at least one thermally activatable or encapsulated hardener material.

Insulation system for electrical machines

Casting compound suitable for casting an electronic module, in particular a large-volume coil such as a gradient coil, which is composed of a support material forming a matrix, one or more fillers made of inorganic microparticles, and at least one filler made of polymer nanoparticles.

Casting compound suitable for casting an electronic module, in particular a large-volume coil such as a gradient coil

A superconducting coil for a magnetic resonance apparatus is formed by one or more wound superconducting conductors that are embedded in a cured sealing compound, with a filler composed only of nanoparticles added to the sealing compound.
