[0003] However, in the prior art, after a part of the existing composite insulating paper is disassembled and used, the remaining composite insulating paper is prone to scatter when stored, and such a situation easily causes the inside of the unused composite insulating paper to be contaminated with dust and impurities, thereby affecting the stability of the performance of the unused composite insulating paper, and further may reduce the service life of the unused composite insulating paper, thereby reducing the use effect of the composite insulating paper and also reducing the use efficiency of the composite insulating paper.

[0004] Therefore, we propose a composite insulating paper to solve the technical problems raised in the background technology. Utility Model Content
