ACSR (Aluminum Conductor Steel Reinforced) conductors are widely used in long-distance and large-span overhead power transmission lines. Their unique combination of high electrical conductivity from aluminum and excellent mechanical strength from steel makes them ideal for complex geographical environments such as rivers, mountains, and valleys.

However, customers may notice that ACSR conductors with similar structures often differ in quality, price, and service life. This variation mainly results from differences in raw materials and manufacturing standards adopted by different producers.

Key Material Differences

• Aluminum Wire Quality
  Inferior aluminum wires may fail to meet essential performance standards such as tensile strength, elongation, and winding test requirements. They may also exhibit excessive twist pitch, reducing conductor stability and lifespan.

• Galvanized Steel Wire Quality
  The quality of the steel core largely depends on the zinc coating thickness and uniformity. Poor-quality galvanized steel wire with an insufficient or uneven zinc layer is prone to corrosion, which can significantly shorten the conductor’s service life.

Why Professional Testing Matters

Many of these performance issues are not visible to the naked eye. Reliable evaluation of ACSR quality requires professional testing equipment to assess electrical, mechanical, and corrosion-resistant properties accurately.

We encourage both new and long-term customers to verify technical parameters and choose high-quality ACSR conductors from reputable manufacturers. Our products strictly comply with international standards and undergo rigorous quality inspections to ensure excellent performance and durability in demanding environments.
