TransPowr® ACSR/SD Bare Overhead Conductor (Canada)

TransPowr® ACSR/SD Bare Overhead Conductor (Canada)
Product description

ACSR/SD conductors are constructed from two layers of 1350 H19 trapezoidal aluminum wires, concentrically stranded around a steel core of round-coated steel wires. In some larger conductor designs, the trapezoidal wires are encased in a layer of round 1350 H19 aluminum wires. A gap separates the steel core from the two layers of trapezoidal-shaped aluminum wires, which helps provide self-damping. The steel core wires are protected from corrosion by coatings made of aluminum-clad, galvanized, or a zinc-5% aluminum mischmetal alloy. Additionally, options for standard, high, extra-high, and ultra-high-strength steel are available. The manufacture of ACSR/SD conductors complies with the requirements of the latest version of ASTM B701.

 

Features and Benefits

The ACSR/SD (Aluminum Conductor Steel Reinforced/Self-Damping) design features a steel core surrounded by two layers of trapezoidal aluminum wires, with a gap intentionally created to provide self-damping. This helps control Aeolian vibrations, eliminating the need for additional vibration dampers. 

Using ACSR/SD offers several advantages, including:

  • Shorter and more cost-effective towers
  • Increased overall reliability
  • Lower total line costs
  • Reduced sag
  • Less susceptibility to ice and wind loads
  • The ability to accommodate longer spans

 

Applications

ACSR/SD conductors are used for overhead transmission lines to control Aeolian vibration.
