Highland barley paper, also known as green shell paper or electrical insulation paper, is widely used in motor manufacturing due to its excellent electrical insulation performance and mechanical strength. It can not only effectively isolate electrical components and prevent short circuits and other electrical faults, but also maintain stable performance under harsh conditions such as high temperature and high voltage.1. Electrical insulationOne of the main functions of highland barley paper is to provide reliable electrical insulation. The motor contains multiple conductive parts, such as winding coils, terminal blocks, etc., and these parts must be well electrically isolated to avoid short circuits or leakage. Highland barley paper has high dielectric strength and can withstand high voltages without breakdown, thus ensuring the safe operation of the motor.Dielectric strength: Highland barley paper usually has high dielectric strength, which means that it can work stably in a high voltage environment and will not cause insulation failure due to excessive voltage.Resistivity: Highland barley paper has good resistance characteristics, which can prevent current from passing through and ensure the independence of each electrical component.2. Thermal stabilityThe motor will generate a lot of heat during operation, especially when it is running at high load for a long time. If the insulation material cannot withstand high temperature, it may cause the insulation layer to age, become brittle or even melt, which may lead to safety accidents. Highland barley paper has good thermal stability and can maintain its physical and chemical properties in a wide temperature range.Wide temperature range: Highland barley paper can be used normally in the temperature range of -60°C to +130°C, and some special models of highland barley paper can even work at higher temperatures.Anti-aging performance: Even in a long-term high temperature environment, highland barley paper is not easy to oxidize or degrade, which extends its service life.3. Mechanical strengthThe internal structure of the motor is complex, and the various components need to work closely together to ensure the normal operation of the equipment. In addition to having excellent electrical insulation performance, highland barley paper also has a certain mechanical strength. It can be used as a gasket, bushing and other parts to play a supporting and fixing role.Combination of flexibility and rigidity: Highland barley paper is both soft and hard, can be cut into various shapes according to needs, and is not easy to tear or deform.Impact resistance: When the motor is subjected to vibration or impact, highland barley paper can absorb part of the energy, reduce the impact on other components, and protect the overall structure from damage.4. Moisture and waterproof performanceHumidity is one of the important factors affecting the insulation performance of the motor. Moisture entering the interior of the motor may cause the insulation material to absorb moisture, reduce its insulation resistance value, and increase the risk of leakage. Highland barley paper has good moisture and waterproof performance, which can effectively block the intrusion of external moisture and maintain a dry internal environment.Low water absorption rate: Highland barley paper has a low water absorption rate and can maintain good insulation effect even in a humid environment.Waterproof coating treatment: Some highland barley paper surfaces are specially treated (such as impregnated with resin) to further enhance its waterproof ability.5. Processing flexibilityHighland barley paper is easy to process and can be cut and stamped into various sizes and shapes according to actual needs to meet the design requirements of different motors. For example, it can be made into gaskets for sealing interfaces, or as gear bushings to reduce friction losses.Die stamping: Highland barley paper can be stamped into specific shapes of parts, such as gaskets, bushings, etc. using dies to adapt to complex motor structure designs.Customized services: According to the specific needs of customers, manufacturers can also provide customized services in terms of thickness and size to ensure that each piece of highland barley paper can perfectly fit the corresponding installation position.In summary, highland barley paper plays a vital role in insulation protection in motors with its excellent electrical insulation performance, excellent thermal stability and mechanical strength, and good moisture and water resistance. Whether as a spacer between windings or as an end tie, highland barley paper provides a solid guarantee for the safe and reliable operation of the motor.
