Copper has been the preferred material for electrical wiring for decades, and for good reason:
✅ High Conductivity – Copper offers superior electrical conductivity, minimizing energy loss.
✅ Durability – Resistant to corrosion and wear, ensuring long-term reliability.
✅ Flexibility – Easy to bend and install without compromising performance.
✅ Heat Resistance – Handles high temperatures better than aluminum alternatives.
✅ Safety – Low risk of overheating, reducing fire hazards.

1. Why is copper better than aluminum for connecting wires?
Copper has higher conductivity (about 60% more efficient than aluminum), better resistance to corrosion, and greater flexibility. Aluminum wires are cheaper but require thicker gauges to match copper's performance and are more prone to oxidation over time.
2. How do I choose the right size of copper connecting wire?
The correct wire size depends on:
Current load (higher amps require thicker wires)
Voltage drop limits (longer runs may need larger diameters)
Environmental conditions (temperature, moisture, etc.)
Refer to our comparison table above or consult an electrician for precise selection.
3. Can Xiamen Jinguo Jinbei Cable Sales Co., Ltd. provide customized copper wires?
Yes! We offer tailored solutions including:
Special insulation materials (silicone, Teflon, etc.)
Different strand types (solid core or flexible stranded)
Custom lengths and colors for easy identification
