Detailed explanation-1: -Rubber is known to be an insulator because rubber can limit the transfer of electricity. The rubber properties prevent the electrons to be able to freely move and the addition of the electrons being tightly bounded makes rubber a good insulator .

Detailed explanation-2: -Copper wires are jacketed inside a layer of rubber. This is because rubber is an insulator.

Detailed explanation-3: -Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators.

Detailed explanation-4: -Examples of insulators are glass, air, wood, plastic and rubber.

Detailed explanation-5: -Rubber has been used as cable insulation and sheathing material long before other insulation such as PVC and PE can to be commonly applied. It remains widely used across domestic and industrial applications. Initially, natural rubbers were used but these have been largely replaced by various synthetic rubbers.
