ACSR (Aluminum Conductor Steel Reinforced) cable remains one of the most trusted conductors for medium-to-long-span overhead transmission thanks to its superior tensile strength, stable conductivity, and field-proven durability. As global grid expansions push toward higher efficiency, better corrosion resistance, and long-term stability, engineering teams and procurement specialists continue to rely on ACSR conductors for dependable performance.

HNBF Power—an established manufacturer of overhead conductors including AAC, AAAC, ACSR, ABC cable, and LV power cables—delivers precision-engineered ACSR cables manufactured under strict quality standards. With advanced stranding technology, optimized conductor lay ratios, and robust steel core reinforcement, HNBF Power ensures every ACSR unit performs reliably in demanding environments.


What Is ACSR Cable?

ACSR cable is a composite stranded conductor consisting of:

  • Outer layers of hard-drawn aluminum strands for excellent electrical conductivity

  • A central steel core that provides outstanding mechanical strength and prevents sag over long spans

This unique construction allows ACSR to accommodate high mechanical loads, making it ideal for transmission lines exposed to wind, ice, and long-distance tension requirements.

HNBF Power manufactures ACSR cables using high-purity aluminum and galvanized or aluminum-clad steel, ensuring enhanced corrosion resistance and prolonged service life.


Key Advantages of ACSR Cable

1. High Tensile Strength

The steel core significantly boosts tensile performance, enabling longer spans with minimal sag. This is essential for transmission lines crossing rivers, valleys, and industrial corridors.

2. Excellent Conductivity

The high-grade aluminum layers provide efficient current flow, optimized for power transmission systems requiring stable electrical performance.

3. Strong Weather and Stress Resistance

ACSR maintains mechanical stability under:

  • Heavy wind loading

  • Ice accumulation

  • Thermal expansion

  • High ambient temperatures

HNBF Power’s ACSR cable designs are engineered to withstand harsh climates and demanding installation conditions.

4. Long Service Life

With advanced surface coating (galvanized or aluminum-clad steel), corrosion is minimized, ensuring long-term reliability even in coastal or industrial regions.


Applications of ACSR Cable

ACSR conductors are widely used in:

  • High-voltage and extra-high-voltage transmission lines

  • Long-span overhead lines

  • Distribution systems requiring high mechanical performance

  • Expansion or upgrading of national grid infrastructure
