About 3M Power Transmission
-
Invest in the reliability and efficiency you’ll need for decades to come.
We apply 3M Science to help you build power transmission for the long haul, both in distance and decades. Take advantage of our conductor materials research to double the load on your existing lines. Tap into our field experience to build high-voltage underground systems that are easier to install, manage, and maintain. Protect the integrity of your grid, and get more out of it, with power transmission solutions you can trust—from 3M.

3M™ Aluminum Conductor Composite Reinforced (ACCR)3M ACCR is an overhead aluminum composite conductor that is lighter than, and as strong as, steel core conductors. With 3M ACCR, there’s far less sag to carry more load. You could double the capacity of an existing line without exceeding the mechanical or clearance limits of the existing towers. You’ll also simplify permitting, condense schedules, and minimize community environmental disruption.

High Voltage Cable AccessoriesYour transmission lines are installed to perform for decades. That’s why we designed 3M high voltage underground cable accessories to withstand harsh environments and rugged installation conditions. One example: 3M™ Cold Shrink Products that install in one-third of the time needed for heat shrink, and without special tools or work permits, to help keep your project on schedule.

Efficiently increasing the capacity and reliability of the power transmission grid is a problem perfectly suited for 3M.
For the 3M™ Aluminum Conductor Composite Reinforced (ACCR) high-capacity transmission conductor, our materials scientists developed a high-strength, lightweight aluminum composite core and combined it with a hardened aluminum-zirconium alloy for the outer, current-carrying strands. Together, they make 3M ACCR similar in construction and dimensions to ACSR. Yet 3M ACCR is lighter and sags less, even at higher operating temperatures–allowing higher ampacities at equivalent tensions and clearances.
For faster, easier installation of splices and terminations, 3M electrical accessory experts developed Cold Shrink technology. 3M™ Cold Shrink Products contain elastomeric bonds that, when allowed to shrink onto a cable, exert a strong inward force that produces a constant squeezing force on the cable. It’s a “living seal” that expands and contracts with changes in temperature and load for long-term performance and protection.
