Overhead conductors play a critical role in modern power transmission and distribution networks. As utilities, EPC contractors, and industrial buyers seek higher efficiency, increased durability, and long-term system reliability, choosing the right conductor type becomes a strategic engineering decision. HNBF Power, a global manufacturer of AAC, AAAC, ACSR, ABC, LV power cables, and concentric cables, provides advanced overhead conductor solutions engineered for superior mechanical strength, conductivity, and performance in harsh environments.
This article explores the key types of overhead conductors, performance characteristics, engineering considerations, and why technical professionals worldwide trust HNBF Power for consistent quality and dependable supply.
What Is an Overhead Conductor?
An overhead conductor is the current-carrying component of overhead transmission and distribution lines. Designed for exposed installations, these conductors must withstand electrical loads, mechanical tension, fluctuating temperatures, wind pressure, ice loading, and long-term environmental stress.
Key Types of Overhead Conductors Manufactured by HNBF Power
1. AAC – All Aluminium Conductor
AAC is widely used in urban distribution networks where short spans and superior conductivity are required. HNBF Power manufactures AAC with high-purity aluminium, offering:
Excellent electrical conductivity
Lightweight structure
Corrosion resistance, ideal for coastal installations
2. AAAC – All Aluminium Alloy Conductor
AAAC provides higher strength than AAC and better sag performance under heavy loads. It is engineered for:
Longer spans
Improved resistance to wind and ice
Reduced maintenance in harsh climates
3. ACSR – Aluminium Conductor Steel Reinforced
ACSR combines aluminium strands with a steel core to deliver exceptional tensile strength. HNBF Power supplies various steel-reinforcement ratios to meet diverse transmission requirements. Benefits include:
High mechanical strength
Superior sag control
Ideal for long-distance transmission lines
4. ABC – Aerial Bundled Cable
ABC systems are increasingly replacing bare conductors in urban areas for improved safety and reduced theft risk. HNBF Power’s ABC conductors provide:
Excellent insulation performance
Lower short-circuit risks
Safer installation in congested zones
