METHOD FOR PRODUCING WRAPPING TAPES FOR HIGH VOLTAGE INSULATION OF ELECTRICAL MACHINES AND APPARATUS AND WINDING TAPE FOR PRODUCING AN INSULATING SLEEVE FOR ELECTRICAL LADDERS.

摘要

High-voltage insulation in which mica tape employing a binder resin is used for wrapping around electrical apparatus, and the wrapped apparatus is impregnated with a heat-setting epoxy resin. The binder resin for the mica tape is a polyester containing a tertiary-bound nitrogen which is effective as an adhesive for the tape and also as an accelerator for the epoxy resin.
