1. Conductivity
Conductivity is a core performance characteristic of power cables. Copper conductors offer superior conductivity compared to aluminum conductors; consequently, copper-core cables are more widely used in environments requiring a stable power supply. Aluminum-core cables, however, are lighter in weight, making them suitable for large-scale power transmission, particularly over long distances.
2. Durability and High-Temperature Resistance
Cross-linked polyethylene (XLPE) cables exhibit excellent high-temperature resistance, making them suitable for high-temperature environments and high-voltage power transmission. In contrast, plastic-insulated cables perform better at lower temperatures and are suitable for indoor power systems.
3. Safety
The safety of a power cable depends on the quality of its insulation layer. High-quality insulation effectively prevents current leakage and electrical fires, ensuring the stable operation of the power system.
