Basic characteristics of aluminum-core cables
Due to the properties of the material, aluminum-core cables offer the advantages of being lightweight and cost-effective. Compared to copper-core cables, aluminum has a conductivity of approximately 60% that of copper; consequently, to achieve the same current-carrying capacity, aluminum-core cables typically require a larger cross-sectional area.
Suitable applications for aluminum-core cables
- Fixed installations: e.g., power transmission trunk lines and building power distribution systems
- Temporary power scenarios: e.g., temporary power supply for construction sites and power distribution for event venues
- Long-span overhead lines: leveraging the lightweight nature of aluminum to reduce the cost of supporting structures
Practical advice on cable selection
- When considering long-term usage costs, factor in both the initial investment and differences in energy consumption.
- Pay special attention to oxidation at connection points; the use of specialized terminals is recommended.
- The required bending radius is 30% larger than that of copper cables; ensure sufficient space is reserved during installation.
