Light and Low-Cost Choice
Aluminum overhead cable is made of high-purity aluminum. Its density is one-third that of copper, which makes the cable lightweight. It places a low load on poles, and the cost remains low. It is suitable for very long spans and large power grids. It offers good conductivity, high tensile strength, and strong weather resistance. This product performs well in environments with sand, salt, sunlight, and temperature variations.
High Purity for Low Loss
The conductor uses 1350H19 aluminum with a purity of not less than 99.5%. Conductivity reaches 61% IACS. The resistance at 20°C is very low, resulting in high transmission efficiency and minimal power loss. The stranding consists of 7, 19, 37, or 61 wires, providing good flexibility. It has strong creep resistance and tensile stability. The cable does not elongate significantly during long-term suspension. Thermal expansion is well controlled, and heat stability is good. This aluminum overhead cable operates at a low temperature even under high current load.
Natural Rust Protection
Aluminum naturally forms a dense oxide layer on its surface, which prevents corrosion. The cable can be used near the sea, in industrial areas, and at high altitudes for 20 to 30 years. It resists wind vibration, ice, and sunlight exposure. Mechanical stability remains high, and breakage is rare. Installation is simple, and connections are easy to perform. Maintenance costs are very low. This aluminum overhead cable is suitable for high-voltage lines, rural distribution networks, and new energy collection lines.
