Emulsions for drawing Bechem took the opportunity offered by wire 2008 to demonstrate its emulsions for aluminium multiwire drawing.

Conventional have previously been used for the drawing of aluminium and aluminium alloy wires, and especially rod wire drawing. However, the partially highly viscous media are linked with known disadvantages, such as impossible filtration. Bechem’s Berudraw products have a lower viscosity, and are said to offer improved filterability, residue-free wires oils

and more stable drawing processes. Using emulsion for multiwire drawing allows a cleaner and more pleasant working environment that cannot be achieved with conventional drawing oils. Clean drawing machines and optimal filtration provide an almost residue-free finished product with a high quality surface finish.

HVDC cable to link Finland and Sweden

Nexans has been awarded a contract by Fingrid Oyj, the electricity transmission system operator in Finland, and Svenska Kraftnät, a state utility which runs the national electrical grid in Sweden. The contract is for the manufacture and installation of a High Voltage Direct Current (HVDC) submarine power cable for Fenno-Skan 2, the new power interconnector between Finland and Sweden. Nexans will supply around 200 km of specialised solid, oil-impregnated MIND (Mass Impregnated Non-Draining) cable for both the subsea and land based elementsoftheFenno-Skan2interconnector. With a copper cross-section of 2,000mm 2 , this will be the largest capacity HVDC cable manufactured by Nexans to date. The Fenno-Skan 2 HVDC project will create a new 800 MW, 500 kV subsea electri- city transmission connection between southern Finland and Sweden, following a 200 km route across the Gulf of Bothnia. It will form a bipolar arrangement with the existing 550 MW, 400 kV Fenno-Skan link, commissioned in 1989, to provide a 40 per cent increase in power transmission capacity between the two countries. Manufacture of the Fenno-Skan 2 cable will start in Autumn 2009.

The installation of the subsea cable, at a maximum sea depth of 100m, will be carried out by Nexans’ own cable laying ship, the CS Skagerrak, and this is scheduled for spring 2011. The cable will be supplied in two continuous lengths of around 100 km, with just one offshore joint. “This major contract for the Fenno-Skan 2 project reinforces Nexans’ position as a key manufacturer and installer of high-technology cables for subsea power interconnectors,” commented Patrick Barth, MD of Nexans’ high voltage activity.
