Machine taping of resin-rich micapaper to high voltage stator coils for operation in all types of rotating machines up to 30 kV

Machine taped coils insulated with a Resin Rich B Stage glass backed mica paper tape have now been in production for a number of years. This process allows all the main wall insulation to be applied and consolidated in one application to all types of coils without any vacuum treatment. The system can be used at Class F temperatures. No voltage restriction has been made and the production processes have been developed for use up to 30 kV.
