The present invention discloses a process for producing a high-quality insulation for conductors or conductor bundles of electrical machines by means of spray-sintering. Unlike in the prior art, it is possible to apply internal corona-discharge protection, insulation and external corona-discharge protection to conductors or conductor bundles in which, on account of a very low level of defects in the insulation and its inherent resistance to partial discharges, it is possible to dispense with the use of winding processes using glass/mica tapes. This eliminates the need to use complex special equipment and allows the throughput times to be shortened considerably.
A process for producing a high-quality insulation for conductors or conductor bundles, comprising the steps of:
The process as claimed in one of the preceding claims, comprising the further step of
The process as claimed in one of the preceding claims 1 to 18, in which step S4 comprises charging the coating material before it is applied to the conductor surface, in which case this charging may be electrostatic or triboelectric, so that thicker coating takes place at edges.
