What is the difference between insulated and non-insulated conductors?

Insulated conductors feature a protective covering made from materials such as rubber or plastic, which serves several essential functions. This insulation helps to prevent accidental contact with the conductor, enhancing safety by reducing the risk of shock or electrical accidents. Furthermore, the insulation acts as a barrier against environmental factors such as moisture, chemicals, and physical damage, thus prolonging the life and reliability of the conductor.

In contrast, non-insulated conductors lack this protective covering, making them more susceptible to direct contact and environmental hazards. While they may be suitable for specific applications where exposure is controlled, their use generally requires careful handling to avoid electrical hazards.

This understanding of insulation is critical in electrical work, as it directly relates to safe practices and proper application in various electrical systems.
