AHA insulation paper is an insulation material composed of a polyimide film in the middle and aramid paper on both sides and coated with H-grade adhesive. AHA insulation paper has good mechanical and electrical properties. And it is suitable for slot, slot cover and phase insulation of high heat resistance motors.
Polyimide film: Polyimide is a high-performance polymer with excellent heat resistance, mechanical strength and chemical stability. In AHA insulation paper, the polyimide film acts as an intermediate layer to withstand voltage, isolate current and transfer heat.
Aramid paper: Aramid paper is an insulation paper made of aramid fibers, which has the characteristics of high strength, high modulus, high temperature resistance and chemical corrosion resistance. In AHA insulation paper, aramid paper serves as a cover layer on both sides, enhancing the overall mechanical and electrical properties of the material.
Adhesives: Adhesives are the key material for connecting polyimide films and aramid paper. In the production process of AHA insulation paper, it is necessary to select adhesives with excellent heat resistance and electrical properties to ensure the overall performance of the composite material.
Heat resistance grade: The heat resistance level of AHA insulation paper is H grade (180℃), and it has good high temperature resistance.
Good mechanical properties: AHA insulation paper has excellent tensile strength and edge tear properties, and can withstand large mechanical stresses. At the same time, its surface is smooth and easy to process and install.
Excellent electrical performance: AHA insulation paper has good electrical properties such as electrical strength, insulation resistance and breakdown voltage. And it can meet the requirements of electrical equipment for insulating materials.
Chemical corrosion resistance: AHA insulation paper has good corrosion resistance to a variety of chemical substances and can maintain stable performance in harsh chemical environments.
Because AHA insulation paper has excellent performance characteristics, it has been widely used in electrical equipment. Here are some of the main application areas:
Motor: AHA insulation paper can be used for motor slots, slot covers and interphase insulation, as well as transformer interlayer insulation. Its excellent heat resistance and mechanical properties can ensure the stability and reliability of the motor at high temperature and high speed operation.
Transformer: Components such as windings, cores and insulating structures in transformers need to use insulating materials to isolate current and transfer heat. AHA insulation paper has been widely used in transformers due to its excellent heat resistance and electrical properties.
Reactor: The coils and insulating structures in the reactor also require the use of insulation materials. AHA insulation paper can meet the requirements of reactors for insulating materials and ensure the normal operation of the reactors.
AHA insulation paper is a high-performance composite insulating material. With its excellent heat resistance, electrical properties, mechanical strength and chemical resistance, it has been widely used in power transformers, motors, reactors and other equipment. With the advancement of technology and the development of the market, AHA insulation paper will play a more important role in the future and provide strong support for the stable operation and efficient development of electrical equipment.
