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.
