1, application areas: different application areas of the electrical properties of insulation materials require different. For example, high-voltage power equipment, electronic devices, medical equipment, etc. require different insulation materials and different dielectric strength standards.
2, the type of material: different insulation materials, such as polymers, rubber, ceramics, etc., its electrical properties will be different. The chemical structure of the material, molecular arrangement and other factors will affect its dielectric strength.
3, equipment requirements: the design and operating conditions of electrical equipment will also affect the standard of insulation dielectric strength. High-voltage equipment requires higher dielectric strength to ensure safety performance.
