- Dielectric Strength: The dielectric strength of insulation material determines its ability to withstand high voltages without breaking down. High dielectric strength materials help prevent electrical breakdown and ensure reliable insulation performance.
- Thermal Conductivity: Insulation materials with low thermal conductivity help maintain stable operating temperatures within the generator, preventing overheating and thermal degradation of insulation.
- Moisture Resistance: Insulation materials should resist moisture ingress to prevent degradation, reduced dielectric strength, and insulation breakdown, ensuring long-term reliability in humid or wet environments.
- Mechanical Strength: Insulation materials should possess adequate mechanical strength to withstand mechanical stresses, vibrations, and thermal expansion/contraction cycles without cracking or delamination, ensuring durability and reliability under operational conditions.
- Chemical Resistance: Resistance to chemical degradation from oils, fuels, solvents, and other contaminants helps ensure insulation materials maintain their electrical and mechanical properties over time, enhancing reliability and longevity.
- Aging Characteristics: Insulation materials should exhibit stable aging characteristics, resisting degradation and maintaining performance over the operational lifespan of the generator, ensuring long-term reliability and efficiency.
- Compatibility: Insulation materials should be compatible with other materials in the generator, such as conductors, coatings, and structural components, to prevent compatibility issues that could compromise insulation integrity or reliability.
- Environmental Considerations: Insulation materials should be selected based on environmental factors such as temperature extremes, humidity levels, UV exposure, and exposure to harsh chemicals or contaminants, ensuring reliable performance in diverse operating conditions.
- Electrical Properties: Insulation materials should possess desirable electrical properties, such as high electrical resistivity, low dielectric loss, and stable dielectric constant, to ensure effective electrical insulation and minimize energy losses in the generator.
- Cost-effectiveness: The choice of insulation material should balance performance requirements with cost considerations, selecting materials that provide optimal reliability and efficiency within budget constraints, ensuring cost-effective operation over the generator’s lifespan.
