Aluminium Conductor Composite Core

Why Choose Us?

Leveraging a high-strength carbon core encased in concentric, round or trapezoidal aluminium designs, Aluminium conductor composite core deliver industry-leading ampacity, low sag, and superior thermal performance, making them ideal for upgrading existing lines and powering long-span transmission.

Composite Core Strength

Carbon-fiber core provides exceptional tensile capacity with minimal weight.

High Current Capacity

 Low AC resistance and high allowable operating temperature (up to 180 °C) boost ampacity by up to 70 % over conventional ACSR.

Low Sag

 Outstanding modulus of elasticity (118 GPa above thermal knee) keeps conductor profile tight, even under heavy loads.

Thermal Stability

 Operates continuously at 175 °C surface temperature with AC resistance as low as 0.416 Ω/km (e.g. 530 mm² size).

Lightweight & Corrosion-Resistant

 All-aluminium outer layers resist corrosion—ideal for coastal or polluted environments.

Extended Service Life

 High fatigue resistance for long spans and harsh weather conditions.

Applications

  • Capacity upgrades on existing overhead lines without changing towers
  • Long-span and extra-high-tension crossings (rivers, valleys)
  • Renewable energy evacuation (wind farms, solar parks)
  • Urban network reinforcement with low-sag requirements
  • Retrofit projects where right-of-way expansion is limited

Applicable Standards

  • ASTM B987 – Specification for carbon composite cores
  • EN 50540 – Conductors of insulated cables
  • BS EN 50183 – Aluminium Conductor Composite Core for overhead lines
