GER SA has manufactured a newly designed continuous resistance annealer for copper wire, the 3000A model. This annealer can be combined with any make of rod breakdown machine, due to its self-contained design and motorisation. It can be used to anneal copper wire in a diameter range from 1mm–3.4mm, equipped with a 22kW AC motor with a frequency control system. Annealer model, 220A, is also available for fine copper wire drawing machines. It is also a standalone model with a 15KVA transformer, 120mm diameter contact pulley, wire diameter range of 0.15mm to 0.5mm, and a maximum speed of 30 metres per second. This model is offered with either its own drive motor or driven from the drawing machine by a flat belt. New copper wire annealers

Nexans has been awarded a €13 million turnkey contract to supply the power cables for the new Kraftwerke Linth-Limmern pumped-storage hydropower plant currently under construction in the Linthal Valley in eastern Switzerland. This contract covers the design, manufacture and supply, installation, connection and commissioning of about 30km of extra high voltage (EHV) cables. The company will supply six 380kV XLPE-insulated underground cables, each approximately 5km in length, which corresponds to the length of the underground access tunnel in which they will be installed. Laid in parallel to connect the new plant to the EHV power transmission grid, these cables will comprise copper core conductors with a cross-section of 1,600mm 2 . The Limmern pumped-storage project will utilise the proximity of two existing water-holding reservoirs – the Muttsee Lake and the Limmernsee Lake – by building an underground pumped-storage plant between them. During the day, when power demand is at its peak, water will be released through the turbines of the new Limmern plant to generate electric power for the coverage of demand peaks. At night, as demand decreases, a larger amount of electric power is available on the grid and this will be used by the new Limmern plant to pump water back upstream, from Limmernsee into Muttsee. With its ability to pump water back from the lower into the higher reservoir the plant acts like a huge rechargeable battery, using readily available night time power to provide a very reliable and flexible power supply that can cover peak demand during the day. The same power lines, connected to the Swiss national EHV power transmission grid, will provide the electric power required to pump back water as well as exporting the power generated by the plant when it is operating in turbine mode. This connection will be provided by Nexans’ 380kV cables. EHV for hydropower project

Inosym ships its largest reels

In December 2009 Inosym shipped its “largest ever” reels to Egypt and Malaysia. The reels were steel drums of 4,000mm and 3,600mm in diameter. The drums were designed to carry a maximum cable weight of 25,000kg at drum twisting speeds of up to 28rpm. Inosym’s engineering and logistics teams can design, manufacture and deliver worldwide a comprehensive range of reels and drums for all cable making processes.
