This disclosure relates to an electrical insulation paper comprising at least 25% content by weight of cellulose fibers based on the total weight of the electrical insulation paper, 8% content by weight of synthetic fibers based on the total weight of the electrical insulation paper, and a thermal stabilizer comprising nitrogen, wherein a content by weight of the nitrogen constitutes between 1% and 4% of the content by weight of the cellulose fibers.

The utility model discloses electrical insulation paper for preventing insulation breakdown, which comprises a polyethylene core layer, heat dissipation coatings, a hollow fiber layer and a high-temperature-resistant external insulation layer, the heat dissipation coatings are arranged on two sides of the polyethylene core layer, the hollow fiber layer is arranged on one side of the heat dissipation coatings, and the high-temperature-resistant external insulation layer is arranged on one side of the hollow fiber layer. The electric insulation paper is reasonable in structural design, the loose and porous heat dissipation coating is adopted, the edge part of the heat dissipation coating is arranged outside, the heat accumulation amount of the area of the electric insulation paper can be reduced, and meanwhile the hollow fiber layer is matched, so that the circulation performance of air flow in the electric insulation paper can be enhanced, and the flexibility and elasticity of the electric insulation paper can be enhanced.

The utility model belongs to the field of electrical insulation paper production, and particularly relates to an electrical insulation paper automatic winding device with a fixed-distance cutting function, which comprises a winding device main body, and the outer wall of the winding device main body is fixedly connected with an adjusting assembly. And the adjusting assembly comprises a mounting table, an electric air cylinder, a telescopic frame, a screw rod, a fixing nut, a moving frame, an electric push rod and a fixing block, the electric air cylinder is fixedly connected to the interior of the mounting table, and the telescopic frame is fixedly connected to one end of the electric air cylinder. According to the automatic winding device with the fixed-distance cutting function for the electrical insulation paper, the effect of cutting the electrical insulation paper in different sizes is achieved through cooperation of the adjusting assembly, a screw rod is in threaded connection with the interior of a telescopic frame according to the width of the electrical insulation paper, and the cutting efficiency is improved. The fixing nut is rotated to be in threaded connection with the outer wall of the screw rod to lock the screw rod, so that the movable frame is fixed, and then one end of the electrical insulation paper is placed in the movable frame.

The utility model discloses an electric insulation paper cutting guide mechanism, which belongs to the technical field of cutting equipment and comprises a base frame, guide frames are connected to two sides of the base frame, a cutting table is connected to the middle of the top end of each guide frame, each guide frame comprises a guide rail frame, and a pressing wheel is coupled to one side of the bottom end of each guide rail frame. The other side of the bottom end of the guide rail frame is connected with a screw rod, and the bottom end of the screw rod is connected with a servo motor. According to the guide mechanism, the sliding grooves are formed in the side faces of the guide rail frame, dust can be prevented from entering the sliding grooves from the top face, the guide rail blocks in the sliding grooves can keep sliding in the transmission guide process through the rollers, friction is reduced and guide stability is improved in cooperation with the rubber layers, and then the purpose of reducing abrasion is achieved; the guide rail frame can be adjusted in a lifting mode through a screw rod, so that included angles are formed between the pressing wheels and the two side ends of the transmission belt, the two sides of the insulation paper raw materials are limited in cooperation with the transmission process, and stability is further provided for the cutting process.
