Nexans-Cable protects St. Petersburg from Floods
Company's 178 km high voltage cables to provide the 25 km long dam's lock with electricity from 2009
Hanover, April 21, 2008 – Nexans Deutschland GmbH & Co. KG is supplying 178 km of high voltage cable for a dam near St. Petersburg by the start of next year. It will protect the metropolis of 4 million from floods in the future. Construction supervisor for this ambitious dam project is the Russian Office for Construction and Infrastructure. The contract for the Nexans cable produced in Hanover valued at several million euros was awarded by the company RosEnergoKontrakt (Moscow).
The cables are to guarantee the electricity supply for the six locks and the 100-metre wide shipping lock. The 110 kV cables have waterproof copper cores with a section of 240 mm² and 185 mm²; their insulation is made of cross-linked polyethylene (PEX). In addition to the cables, Nexans is supplying over 100 muffs and end fastenings for the dam project.
The Flood Protection Barrier System was started over thirty years ago in the Soviet era but had to be temporarily discontinued for political and economic reasons in 1990. In 2006, Russia restarted work on the 25 km long wall of protection and intends to finish it by the end of the coming year. St. Petersburg is frequently a victim of serious flooding due to its location near to water; the last flood devastated the city in 1998. The general contractor for the construction project is the St. Petersburg firm OAO “Metrostroy”.
