Abstract

1. High voltage winding insulation of rotatable electrical machines, comprising a heat-shrinkable organic carrier material coated with hardenable bonding resin and mica, which is wound round all the parts of the winding and compresses these by shrinkage, characterised in that the carrier material is pre-stretched in the winding direction by 8% to 30% and in the transverse direction by 5% at the most, and has a shrinkage initiation temperature in the temperature range for softening the solid bonding resin in the unhardened state, whereby the carrier material is completely shrunk before reaching the hardened state of the bonding resin and is fixed in this state by the hardened bonding resin.
