Device for insulating rod connections with impregnated cured windings in electrical machine, comprises pouch-like insulating caps impregnated by plastic resin.

摘要

A pouch-like insulating cap (3) closed on three sides has a cover that consists of a foil insulating material capable of shrinking under heat. On one side of the cap there is a strip-like projection (4) that projects into a space surrounding an armature end winding. The foil insulating material has several areas of varying material, of which one area has a shrinkable material. The pouch-like insulating cap has insulating tubing that is imperviously bonded on the front side and a welded seam (5) forms strip-like projections like a comb.
