A study of application techniques for mica mat tapes

摘要

The results of this study indicate: 1. Increased voltage life is attainable with wide tapes as contrasted to narrow tapes. 2. Increased voltage life is attainable with thick tapes having an increased mica content. 3. Increased voltage life is related to the flexibility of the tape or wrapper being applied and its ability to conform to the coil. 4. The use of wrappers will provide a significant increase in voltage life as compared to the equivalent build with tapes. 5. Proper indexing of multiple layers of tape will increase voltage life of the insulation wall by as much as 3 fold.
