The Insulating tape of thermal contraction is made from a special compound fiber of thermal contraction. After binding and dried at 105 degree for 10 minutes, it will be shrunk to 70%,which is good at a solid binding and at a compatibility with transformers. In this way, it will be utilized in the transformer oil at 105 degree for a long time.
