3M™ Aluminum Conductor Composite Reinforced Technical Information

3M ACCR's low weight and thermal expansion result in low sag at high ampacities.

  • 3M™ ACCR's low weight and thermal expansion result in low sag at high ampacities.

    The unique combination of an aluminum matrix core and heat resistant Al-Zr outer strands provides many advantages over other conductors.

    Compared to a conventional steel core, the composite core has:

    • Lower thermal expansion for less sag
    • Equivalent strength and durability
    • Less weight
    • Consistent performance at high temperatures over long periods of time

3M ACCR Installation Guide

  • 3M provides on-site training and technical assistance with conductor installation and has a complete line of installation accessories available.

    While the equipment and installation process for 3M ACCR are similar to that for ACSR, there are some slight differences, mostly due to the high temperatures at which 3M ACCR can run. Our engineers and installation experts will ensure your crews understand those differences so the conductor is successfully installed. And if any questions arise during installation, we’ll be available to answer them.
