New record for submarine power cable

Google Translate

Canadian Hydro subsidiary, Canadian Renewable Energy Corporation, has signed a EUR 7 million contract with Paris-based cable maker Nexans for a high voltage submarine power cable for the Wolfe Island Wind Project near Kingston. The 7.8 kilometre long cable will be the first three-core XLPE submarine cable with a voltage rating of 245 kV, says Nexans, beating the record of 150 kV set by the Horns Rev offshore wind farm in Denmark. The cable will be made at Nexans' factory in Halden, Norway, and is to be delivered in May 2008. The wind project, consisting of 86 Siemens 2.3 MW wind turbines, will be built on Wolfe Island at the eastern end of Lake Ontario. Construction is scheduled to start in the spring, with commercial operation expected in October 2008. The cable will be laid on the bottom of the St. Lawrence River at a maximum water depth of 23 metres.
