One of Brazil's largest electric utilities, Companhia de Transmissao de Energia Eletrica Paulista (CTEEP), will install the 3M Aluminum Conductor Composite Reinforced (ACCR) to upgrade the capacity of a key transmission line crossing an environmentally sensitive river bed. The lightweight, sag-resistant 3M conductor provides more than twice the capacity of conventional conductors of similar size without requiring construction of new or enlarged towers.

CTEEP, which is principally owned by Grupo Empresarial ISA (ISA Group), one of South America's largest electricity and telecommunications providers, supplies almost all of the electricity consumed in the State of Sao Paulo and 30% of the electrical power consumed nationwide. The line will boost capacity for power transmission for the Jupiá Electrical System. The line crosses the nearly mile-wide Parana River and is subject to strong winds and extremely high temperatures.
