3M ACCR
Project Profile: River Crossing
Project Overview: Customer: CPFL Paulista Project: Iacanga Substation Location: Sao Paulo, Brazil Length & Voltage: 3.8 conductor miles (6.1 km),
.062 circuit miles (1 km); 138 kV double circuit
Solution: 3M ACCR Type 336 kcmil
Results: Eliminated need for tower on island submerged
during flooding of the Tiet River Avoided the delay of waiting until mid-year for river
to possibly subside Better control over the overall project costs Lower construction risks and environmental impacts Standard maintenance (no need for boats) Ampacity equivalent to ACSR Hawk 477 kcmil
installed on the rest of the line
Building the foundation and tower on submerged land would have posed engineering difficulties; waiting until mid-year for the river possibly to subside would have caused unreasonable delay. Using 3M ACCR was a far more desirable alternative - less costly, and safer for the construction team. - Paulo Ricardo Bombassaro, engineering and planning manager for CPFL Energia.
