The most basic division of wire and cable technology is made on the basis of what?

The most fundamental division of wire and cable technology is based on the voltage. This classification is crucial because different types of wires and cables are designed to handle specific voltage levels, impacting their construction, insulation, and overall performance. For instance, low-voltage cables are often used in residential wiring, while medium and high-voltage cables are essential for transmission and distribution systems in power generation and industrial applications. Understanding voltage classification helps in selecting the appropriate cable for a specific application to ensure safety and efficiency.

While material type, insulation type, and color coding are important factors in wire and cable selection, they are secondary considerations that come into play after determining the appropriate voltage rating for a specific use case.
