High Capacity
ACFR can increase transmission capacity with the following three advantages compared to conventional conductors
More than double under certain design and operation conditions
Larger Aluminum Cross-Sectional Area
CFCC core's durability with high temperature
Annealed Aluminum
Reconductor with
Increase capacity without tower modification
New Line with
Decrease the number of conductors and the tower's structural cost
Low Sag
ACFR is a superior low sag conductor with the following advantages
20% less sag under certain design and operation conditions
Light Weight
High Modulus
Low Liner Expansion
Reconductor with
Sag improvement without tower modification
New Line with
Lower tower height thanks to superior sag performance, which leads to a reduction in the tower construction cost lead time
Longer span thanks to superior sag performance, which leads to a reduction in the construction cost by cutting the number of towers and the lead time
Low Sag - Low Loss and Low Sag - High Capacity design is available.
Special Applications
Anti Corrosion
CFCC core has high corrosion resistance, and better material life is expected compared to conversional steel core conductor.
River Crossings
Major advantage in terms of construction cost and shorter lead time for special long span projects such as river crossings thanks to superior sag performance
