[0010] Preferably, the waterproof layer has a thickness of 5-20 microns.

[0011] Preferably, the thickness of the surface layer is 5-15 microns.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, the waterproof layer is made of polytetrafluoroethylene material with a thickness of 5-20 microns, so that the insulating paper can effectively prevent moisture penetration in a humid environment and maintain the electrical insulation performance and mechanical strength of the insulating paper. The tensile layer is made of glass fiber material with a thickness of 10-50 microns, which provides additional mechanical strength and durability to prevent the insulating paper from being torn due to force during use. Secondly, through the action of the surface layer, the middle layer and the bottom layer, the mechanical strength and structural stability of the entire composite material are enhanced, and at the same time, basic electrical insulation performance is provided, thereby improving the use effect of the high-insulation composite insulating paper.

[0014] 2.
