What are the different types of overhead line conductors and which is best for a given application?

2025-08-13

The choice of conductor is critical for the performance and longevity of a power line. The most common types are based on aluminum, as it offers a superior conductivity-to-weight ratio compared to copper. Each type is designed for specific applications, balancing mechanical strength, electrical conductivity, and cost.

Our professional answer:

Choosing the right overhead line conductor is a key engineering decision. As a leading manufacturer and exporter, Ningbo Changshi offers a comprehensive range of conductors and the equipment needed to install them. The most widely used conductors are:

  • All Aluminum Conductor (AAC): Excellent conductivity and corrosion resistance, ideal for urban and coastal distribution lines with shorter spans.

  • All Aluminum Alloy Conductor (AAAC): Provides higher mechanical strength than AAC, suitable for medium-span distribution and sub-transmission lines.

  • Aluminum Conductor Steel Reinforced (ACSR): The most common choice for long-span transmission lines due to its high tensile strength from the steel core, which supports the lighter aluminum strands.

We provide the necessary OHTLstringingequipment.com/Conductor-Stringing-Equipment.html target='_blank'>conductor stringing equipment to handle all these conductor types, ensuring a safe and efficient installation.
