Insulation paper is a paper material specially designed for electrical insulation, usually made from cellulose fibers (such as wood pulp, cotton pulp or synthetic fibers) through a special process. It has excellent electrical properties, mechanical strength and heat resistance. And it is widely used in various electrical equipment. The main function of insulation paper is to ensure that the current flows along the predetermined path, prevent the current from short-circuiting or leaking inside the electrical equipment, thereby protecting the safety of electrical equipment and personnel.
High insulation resistance: Insulating paper has extremely high resistivity, which can effectively prevent current from passing through non-conductive paths, ensuring the normal operation of electrical equipment and personnel safety.
Good heat resistance: It can maintain the stability of its physical and chemical properties at higher temperatures, avoiding insulation failure caused by temperature rise.
High mechanical strength: It can withstand certain mechanical stress and ensure structural integrity during equipment installation and operation.
Chemical stability: It can resist the erosion of chemicals such as acids, alkalis, and oils, and maintain long-term insulation performance.
Power Transformer: In power transformer, insulation paper plays a key role in preventing short circuit as the insulating layer between windings. It can not only withstand high voltage and temperature, but also maintain stable insulation performance for a long time. In addition, insulation paper is also used for transformer wire winding, layer insulation, segment and box insulation, etc.
Motors and generators: In motors and generators, insulation paper is used for slot wedge insulation, phase insulation, and the fixing and protection of winding ends. These applications rely on the excellent electrical properties and mechanical strength of insulation paper to ensure the normal operation and long-term stability of motors and generators.
Capacitors: As a dielectric material, the insulation paper in the capacitor can improve the energy storage capacity and stability of the capacitor. At the same time, it can withstand various stresses and temperature changes generated by the capacitor during operation.
Cables: In cable manufacturing, insulation paper is used as an inner and outer insulating layer to protect the conductor from the external environment while ensuring the safety of current transmission. This application places high demands on the electrical properties and heat resistance of insulating paper.
Electronic components: In the manufacture of electronic components, insulation paper is often used as an insulating layer on printed circuit boards to prevent interference between circuits. This application requires insulation paper to have excellent dielectric properties and chemical stability.
Insulation paper plays an irreplaceable role in the field of electrical safety. Its excellent performance and wide application areas make it an indispensable and important material in the manufacture of electrical equipment. With the advancement of science and technology and the continuous increase in application demand, insulation paper will continue to play an important role in ensuring the safe and efficient operation of power systems and electronic products.
