The obvious benefit of insulated wire is the color. While this may seem simple, it’s very important, especially in sophisticated wire and cable applications. Colored insulation can help you determine the difference between wires when there are many running together. Designated wires for different applications can help the wired network remain organized.
Wires that are insulated are also corrosion and crush resistant. Ensuring your wire will last is essential to the longevity of your installation.
