Advanced transmission conductor technology that can as much as double transmission capacity in existing corridors with existing structures.
3M ACCR is an advanced transmission conductor designed to replace ACSR or ACSS on existing structures without exceeding existing towers' mechanical or clearance limits. The conductor’s unique properties give you up to twice the capacity, while delivering continued value to the shareholder and reducing ratepayer impacts from major construction projects.
Protecting Grid Integrity – Learn how 3M ACCR can help you meet your transmission challenges while saving time and money.
3M ACCR’s unique properties make it important to consult with a member of our design team to select the most effective and economical option for your application.
What is ACCR? What are the typical uses for the conductor? How is 3M ACCR different from other conductors claiming high temperature, low sag performance? Answers to these and other frequently asked questions.
3M ACCR’s secret is the unique material used in its core. The core is stranded from all metal composite wires of high purity aluminum reinforced with alumina fibers. The outer, current carrying wires are a hardened aluminum zirconium alloy. Compared to the same diameter steel core conductors, 3M ACCR has:
It also retains its performance over decades of high temperature use and is stable in a wide range of environmental conditions.
These attributes can result in two or more times the ampacity while maintaining or improving clearances, tensions and mechanical loads on structures – maximum amps with no compromises.
With 3M ACCR, you make no compromises on your design, operating or installation standards. You get the capacity increase you need and can rely on for decades, even after continuous high temperature operation.
This paper looks at one element of the system – the transmission grid – and how an advanced conductor technology from 3M can help utilities manage grid integrity and affordability in a changing world.
This paper looks at a subset of the new standards – facilities ratings, transmission planning and special protection systems – and how an advanced 3M conductor technology, 3M ACCR, can help simplify compliance and make it more cost effective, while protecting the reliability of the system.
