Proven to Deliver More Amps
3M™ ACCR can double the capacity of an existing line without exceeding existing towers' mechanical or clearance limits.
3M ACCR has proven its ability to perform reliably in a growing number of commercial installations, and over a wide range of tough environmental and operating conditions.
3M ACCR uses all aluminum-based materials - no steel, carbon, polymers or plastics - starting with a core of aluminum oxide fibers embedded in high-purity aluminum. This material has a strength similar to steel, but with less than half the weight and half the thermal expansion.
The all-aluminum-based core and aluminum zirconium outer strands combine to make a conductor that, compared to standard ACSR and ACSS, has:
- Consistent performance at high temperatures, 210° C continuous and 240° C emergency, up to 1,000 hours cumulative less sag due to heat from high energy loads
- Higher strength to weight ratio, so you can maintain mechanical load, tension and clearances, even across long spans, and within your ice and wind loading specifications
- Higher modulus, so it stretches less and is less prone to bird caging during installation than conductors that use annealed aluminum
- Corrosion resistance without coatings or barriers between the core and the outer wire, required for steel or carbon core conductors
- Superior durability and performance, with life expectancy of 40 years or more, even when operated at high temperatures
- More amps on the same size conductor
3M ACCR significantly increases ampacity without increasing sag or mechanical loads
Assumes ACSS and 3M ACCR at 1,300 ruling span, initial tension: 6,557 lbs tension @ 15 deg. C, max. loading @ 30 deg F, 0 ice, 12 lbs wind; amp. conditions: 2f/s wind, 35 deg C ambient, perpendicular wind direction, 0.5 emissivity and solar absorption.
