The fundamental properties of insulation materials are best described by Insulation resistance and dielectric strength.

• Insulation Resistance: This property refers to the ability of an insulating material to resist the flow of electric current. High insulation resistance is crucial for preventing electrical leakage and ensuring safety in electrical systems.
• Dielectric Strength: This is the maximum electric field that an insulating material can withstand without undergoing electrical breakdown, meaning it can maintain its insulating properties under high voltage conditions.
