™
Aluminium Conductor Composite
Reinforced (ACCR)
More amps, more confidence
For your most challenging applications
Higher capacity, lower costs, less installation time and
fewer environmental impacts compared to conventional
upgrade options
Benefits
• Two to three times the ampacity, using existing towers and clearances
• Reduced total project costs
• Proven performance in numerous field installations, several years field
experience around the world and extensive testing
• Avoid the environmental impact of towers and ROW
• Shorter permitting and installation times
• Fully documented installation procedures, design and implementation
support, and a complete range of accessories optimised for 3M ACCR
• Peace of mind from using a technology backed by the technical,
financial and manufacturing resources of 3M
Technology
Advanced aluminium and ceramic fiber composite core wrapped
in high temperature, hardened aluminium outer strands results in:
• Core strength comparable to steel and eight times that of aluminium
• Core weight less than half that of steel
• Core conductivity approximately four times that of steel and
half that of aluminium
• Thermal expansion of the core approximately one-fourth that
of aluminium and half that of steel
• Rated for 210°C/240°C emergency, 1,000 hours cumulative
• Creep lower than steel
• Core stiffness three times aluminium
• Excellent fatigue resistance
• No degradation through corrosion and other environmental factors
• Standard sizes, round or trapezoidal constructions for more energy efficiency
Applications
• Thermal upgrades, such as transmission bottlenecks or high load
growth areas
• Difficult or environmentally sensitive areas, such as mountains,
wetlands, parks and wildlife refuges, or densely populated areas
• Long span, high strength applications, such as river, canyon
or lake crossings
• Corrosive or challenging environments, such as coastal,
desert or cold regions
