What is insulation primarily used for in electrical applications?

Insulation in electrical applications serves the primary purpose of encasing wire or cable in a non-conductive material. This non-conductive layer prevents unintended electrical contact between wires and other conductive materials, which is critical for ensuring safety and functionality in electrical systems. Proper insulation helps to minimize the risk of short circuits, electrical shocks, and other hazards by effectively containing the electric current within the conductor, allowing it to flow only where it is intended.

This insulating layer also contributes to the overall durability and reliability of electrical installations, protecting against moisture, heat, and physical wear that could compromise the integrity of the wires over time. By maintaining the integrity of the conductor and isolating it from surroundings, insulation plays a crucial role in the performance and safety of electrical applications.
