Not only is insulated wire corrosion-resistant, but it is also cost-effective. It's better to buy insulated wire than wire that needs to be repaired or replaced. Replacement or repair of wire will lead to service disruption and cost, which is not ideal.
Safety is essential in wiring applications. Wires carry current that can cause electric shock when touched or cause electrical explosions, shorted wire systems, and more. Insulated wire is the safest choice.
