In modern power transmission systems, the performance of overhead conductors directly affects transmission capacity, line safety, and long-term operating costs.
For decades, ACSR (Aluminum Conductor Steel Reinforced) has been the standard solution for overhead transmission lines. However, with the growing demand for higher capacity and energy efficiency, the new-generation ACCC (Aluminum Conductor Composite Core) conductor is rapidly replacing traditional conductors worldwide.
So what exactly is the difference between ACCC and ACSR conductors? And which one is more suitable for your project?
As a professional overhead conductor manufacturer, Shen Xing Cable Group provides a clear comparison to help you make the most cost-effective choice.
What Is an ACSR Conductor?
ACSR conductor is the most widely used conventional overhead transmission conductor.
Structure
Outer layer: Aluminum strands for electrical conductivity
Core: Galvanized steel strands for mechanical strength
Advantages
Mature and proven technology
Competitive price
High tensile strength
Easy installation and maintenance
Limitations
Heavy weight
Larger sag
Higher thermal expansion
Limited ampacity
Higher energy losses over long distances
What Is an ACCC Conductor?
ACCC conductor (Aluminum Conductor Composite Core) is an advanced high-capacity and energy-efficient conductor designed for modern grids.
Structure
Outer layer: Annealed high-purity aluminum or aluminum alloy for better conductivity
Core: Carbon fiber composite core for lightweight and high strengt
Advantages
30%–100% higher current capacity
25%–40% lighter weight
Lower sag
Very low thermal expansion
Reduced line losses
Ideal for reconductoring and grid upgrades
Longer service life
Limitations
Higher initial cost
Requires advanced manufacturing technology
| Item | ACSR Conductor | ACCC Conductor |
|---|---|---|
| Core Material | Steel | Carbon Fiber Composite |
| Weight | Heavy | Much lighter |
| Ampacity | Standard | 30–100% higher |
| Sag | Larger | Lower |
| Thermal Expansion | High | Very low |
| Energy Loss | Higher | Lower |
| Service Life | 20–30 years | 30+ years |
| Line Upgrade | May require new towers | Can use existing towers |
| Long-term Cost | Higher | More economical |
