Insulation performance: The choice of insulation material directly affects the safety and service life of the wire. For example, PVC-insulated wires are suitable for general environments, whereas XLPE-insulated wires are suitable for high-temperature environments.
Conductivity: The conductor material (such as copper or aluminum) and its cross-sectional area determine the wire's current-carrying capacity and resistance. Copper conductors offer superior conductivity compared to aluminum conductors but come at a higher cost.
Temperature rating: Different insulation materials have varying temperature tolerances; for instance, PVC-insulated wires typically have a temperature rating of 70°C, while XLPE-insulated wires can withstand temperatures of 90°C or higher.
Mechanical strength: The material of the wire's sheath (such as PVC or rubber) influences its tensile strength, compressive strength, and abrasion resistance.
