METHOD FOR PRODUCING A HIGH-QUALITY INSULATION OF ELECTRIC CONDUCTORS OR CONDUCTOR BUNDLES OF ROTATING ELECTRIC MACHINES BY MEANS OF THERMAL SPRAYING

摘要

The invention relates to a method for producing a high-quality insulation for conductors or conductor bundles. According to the inventive method, the inner corona shielding, insulation and outer corona shielding are mounted on the conductor or the conductor bundle in successive steps by means of thermal spraying. The mounting thickness per spraying process amounts to up to 0.2 mm. A flawless layer is thus guaranteed and partial discharges are prevented. Moreover, thermal loading capacity is significantly improved by using high-temperature synthetic materials with fillers consisting of inorganic matters as the coating powder.
