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 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.
Your 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.
