IE Madeira is a consortium comprising the utilities Furnas, Chesf and CTEEP.
The company will supply 6,700 km of its special all-aluminium conductor (AAC) for the first circuit, each conductor features 91 bare wires, with a diameter of 44.4 mm.
The new HVDC link, the first of two, will transmit 3,150MW of power produced by the Rondônia hydroelectric plant in northwest Brazil to São Paulo, Brazil.
HVDC transmission at 600kV will reduce transmission losses and the link will comprise two parallel overhead lines.
The cable is being manufactured at three Nexans plants in Brazil, located in Americana and Rio de Janeiro.
The first transmission line will be installed in the last quarter of 2011, while the entire project will be on line by 2013.
