ACFR
Carbon Core Conductor represents the next generation of high-performance overhead transmission conductors. Designed for superior strength, minimal sag, and maximum current-carrying capacity, Carbon Core Conductor delivers efficiency for modern power networks. With advanced carbon-fiber core technology, it offers a reliable, long-life solution for utilities upgrading aging infrastructure or expanding grid capacity.
Key features
Engineered characteristics
- Ultra-high strength carbon fiber core — lightweight yet significantly stronger than steel; eliminates corrosion; enables long spans and tower optimization.
- High current-carrying capacity — substantial ampacity increases compared to conventional ACSR/ACSR-TW; ideal for reconductoring without tower modification.
- Low sag performance — thermal expansion of the carbon core is ~1/10th that of steel; maintains stable sag under high temperatures.
- Exceptional thermal stability — operates at continuous temperatures up to 180°C; resistant to thermal fatigue.
- Corrosion & fatigue resistance — non-metallic core eliminates galvanic corrosion; extends maintenance cycles and reduces lifecycle cost.
- Higher capacity without new towers, reduced line losses, fast and easy installation with standard equipment, and long service life.
