    摘要： Coil for arrangement in slots in a stator or rotor of an electrical machine, in particular a high voltage coil, and method for manufacturing the coil. The coil comprising a bundle (17) of conductors (18) arranged adjacent to each other.Each conductor is provided with a conductor insulation (19) and a main insulation (14) surrounds the bundle for insulation of the bundle against the walls of the machine slot. The main insulation comprises a wrapping of a tape- or sheet-formed insulating material, wound in several layers around the conductor bundle and comprising a layer with small mica flakes which, as well as the space between layers of mica flakes in the wrapping, contains a cured impregnating resin. According to the invention at least that part of the impregnating resin located in the spaces between the mica layers contains particles of a filler material with an intrinsic thermal conductivity of at least 5 W/mK and with a grain size of the particles of 0.1-15 µm in at least 90 per cent by weight of the filler material.
