As a high-performance insulating material, composite paper is particularly suitable for slot linings and inter-turn insulation in motors and electrical equipment. Its performance in high temperature environments is crucial to ensuring the safe operation of equipment. Through its unique material combination and excellent performance, composite paper can maintain stable performance under extreme conditions to ensure the reliability and safety of electrical equipment.First, composite paper is a composite of polyester film and green shell paper, both of which have excellent heat resistance. Polyester film is known for its excellent thermal stability and can maintain good mechanical strength and electrical insulation properties even under high temperature conditions. At the same time, green shell paper also has excellent temperature resistance. It can not only withstand high temperatures, but also effectively resist the performance degradation caused by thermal aging. This double-layer structure allows composite paper to provide stable protection in the face of high temperature environments, avoiding insulation failure or short circuits caused by overheating.Secondly, the dielectric properties of composite paper are excellent in high temperature environments. Excellent dielectric properties mean that the material can prevent current leakage under high voltage and ensure electrical isolation between components inside electrical equipment. Especially under high temperature conditions, many common insulating materials may have problems such as increased dielectric loss and reduced breakdown voltage, while composite paper, with its special material and structural design, effectively reduces the probability of these problems. This not only improves the safety of the equipment, but also extends its service life.In addition to physical and electrical properties, composite paper's dimensional stability at high temperatures is also a major advantage. As the temperature rises, many materials will expand or contract, resulting in shape changes, which in turn affects the assembly accuracy and operating stability of the entire equipment. However, composite paper can remain almost unchanged in a large temperature range due to the selection of its component materials and the optimization of its manufacturing process. This means that even in a high-temperature working environment, composite paper can still fit tightly to the surface of the equipment without gaps or looseness due to dimensional changes, thus ensuring the long-term stable operation of the equipment.In addition, composite paper also has good flame retardant properties, which is particularly important for improving the safety of the equipment. In electrical equipment, once a fault causes a fire, the flame may spread rapidly and pose a serious threat to the surrounding environment. Composite paper, due to its self-extinguishing characteristics, can extinguish itself when encountering an open flame, preventing the flame from spreading further. This feature greatly reduces the risk of fire and provides an additional safety barrier for the equipment, especially when working in high-temperature environments.It is worth noting that advanced processing technology is usually used in the manufacturing process of composite paper to ensure the close bonding between materials and the consistency of overall performance. High-quality production processes can not only improve the basic properties of composite paper, such as mechanical strength and heat resistance, but also enhance its anti-aging ability. Over time, temperature fluctuations inside electrical equipment may cause the insulation material to gradually age, but specially treated composite paper can better resist the influence of these adverse factors and continue to provide reliable insulation protection for the equipment.From an application perspective, composite paper is widely used in slot linings and inter-turn insulation parts of motors and electrical equipment. These areas are often in high-voltage, high-current working conditions and need to withstand large mechanical stresses. In this case, composite paper, with its comprehensive performance advantages, can not only meet strict electrical requirements, but also remain stable in complex mechanical environments. For example, inside the motor, composite paper can effectively isolate the electrical contact between windings, prevent partial discharge and short-circuit accidents, and ensure the normal operation of the motor under high-temperature operating conditions.Finally, considering the needs of environmental protection and sustainable development, the production of modern composite paper also pays more and more attention to the application of environmentally friendly materials and the implementation of green manufacturing processes. This not only helps to reduce the impact on the environment, but also meets the current social requirements for product life cycle management. Choosing environmentally friendly composite paper as an insulating material can not only ensure the safe operation of the equipment, but also reflect the social responsibility of the enterprise and establish a good brand image.In summary, the outstanding performance of composite paper in high temperature environments is one of the key factors to ensure the safe operation of equipment. Through its unique material combination, excellent heat resistance and dielectric properties, dimensional stability and flame retardant properties, composite paper can provide reliable protection for electrical equipment under extreme conditions and ensure that the equipment can operate efficiently and stably for a long time. At the same time, with the advancement of technology and changes in market demand, composite paper will continue to develop and innovate to meet the needs of more application scenarios in the future and contribute to the development of the power industry.
