FIELD: electricity.
SUBSTANCE: in strip magnetic conductor of distribution transformer manufacturing method the forming of pack block closed circuit is performed by indentation of the block by mandrel, the outer geometry of which is equal to inner geometry of finished strip magnetic conductor, inside the operating cavity of strip magnetic conductor coiling device. Pack block is tightly pressed against the mandrel along its surface. Block ends are fixed at the outer surface in the area of external pack block joint. The laying of the next block is performed by repeating the operation on the formed block till strip magnetic conductor of specified cross-section is obtained.
EFFECT: increase of response speed.
