How should the properties of strength and dielectric strength in insulating materials?

How should the properties of strength and dielectric strength in insulating materials? Correct Answer High strength, high Dielectric strength

The insulator should have high strength in order to prevent the insulating materials. The insulator should have high dielectric strength, in order to hold the electric field without breaking down.
