What is the most basic division of wire and cable technology based on?

The most basic division of wire and cable technology is primarily based on voltage. This categorization helps define the performance and suitability of the wire or cable for various applications in electrical systems. Different voltage ratings indicate the maximum voltage that the wire or cable can safely carry, which is critical for ensuring safety and compliance with electrical codes.

Voltage classification allows electricians, engineers, and designers to select the appropriate type of wire or cable for specific tasks and environments, such as low-voltage, medium-voltage, or high-voltage applications. This ensures that the wire or cable will function effectively without the risk of failure due to overheating, insulation breakdown, or other issues that can arise when operating outside of designed voltage limits.

While material type, insulation type, and application area are also important considerations in the overall functionality and application of wire and cable, voltage serves as the foundational criterion for ensuring that the electrical components operate safely within their specified parameters.
