Nexans Wins a Cable Contract for COMPERJ Complex

Nexans, worldwide leading expert in the cable industry, has been awarded a multi-million Euros turnkey contract by Toshiba Sistemas de Trasmissao e Distribuiçao do Brazil Ltda to supply and install high voltage (HV) XLPE cables and accessories that will be used to interconnect the two main electrical substations at the new COMPERJ petrochemical complex currently under construction in the state of Rio de Janeiro, Brazil.

Petrobras is constructing the COMPERJ complex to help increase Brazil’s capacity to refine oil and reduce the number of petrochemical products it has to import. It is expected to come on line in 2013 and will be capable of processing 165,000 barrels of heavy crude oil per day.

The two main substations at COMPERJ are separated by a distance of around 3.25 km and the Nexans cables will provide a high voltage interconnection with two circuits. Nexans is supplying a complete turnkey solution including a total of 19.5 km of 345kV XLPE-insulated cables with termination, premoulded joints, an earthing system and corresponding installation services.

Specific technological achievement
A key feature of the Nexans XLPE cable for COMPERJ is the smooth aluminium sheath (SAS) manufactured from aluminium laminate laser-welded longitudinally directly over the cable insulation. This design ensures a 100 percent water-tight cable that is also more robust and lighter compared to lead or copper wire sheathing.

A particular challenge for this project is that rather than being installed underground, cables will be carried by pipe racks mounted around 20 metres above the ground. In view of the long lengths of cable being supplied, this method of installation will call for Nexans’ specific expertise and specialized cable-pulling machinery to ensure that the cables are pulled into position with the careful handling essential to avoid excessive and potentially damaging stresses.

Installation of the cables is expected to be complete by 2012. The cables will be manufactured at Nexans plant based in Charleroi, Belgium and the accessories will be provided by the Nexans facility located in Cossonay, Switzerland.

“Our track record has been a key support to demonstrate our expertise in the delivery of end-to-end cable solutions from initial design through manufacture, supply and installation to final commissioning. In light of the strong market penetration Nexans has now in South America, we will continue strengthening our HV positioning in this strategic area” - says Dirk Steinbrink, Nexans Executive Vice President High Voltage & underwater Cable Business Group.
