Power consumption has been reduced: to strand 150mm 2 uses only 40kW of power for the complete line, or 36kW for 120mm 2 . This is thought to be far lower than using a conventional stranding line. It is the result of using regenerative power from the large and heavy built-in reels to produce electricity through a bus connection, so the reels become power generators. A second means to reduce power use is by adapting equipment for lower energy consumption. double twist twinners or bunchers have been equipped with Gauder Group’s new GreenBow, saving 30% energy use on bow motorisation. For example, high-speed

With the emergence of CTC (continu- ously transposed conductor) cables and hybrid motors, the required tolerances for the necessary rectangular copper wires have come down to ±0.005-0.01mm, which are said to be unachievable with traditional cold rolling technology.

Fuhr’s Universal Turks Head

▲

Fuhr will be launching its latest wire rolling technology to enable the manufacture of rectangular copper wire with the lowest tolerances: a combination of Fuhr’s Duo Rolling Mill (WSR type), the patented WST rolling mill and Fuhr’s Universal Turks Head. Another product with demanding speci cations is photovoltaic ribbon. This hot dip-tinned conductor strip (rectangular pro le with a high width/thickness ratio) is installed in photovoltaic (PV) or solar panels, and is made of pure copper (99.99%) or OFC (oxygen-free copper). With Fuhr’s newly developed WSR-type rolling mills, high-precision at copper wire can be produced with the following speci cations: Maximum nal width: 8mm • Maximum nal thickness: 0.4mm • Width tolerance: ± 0.05mm • Thickness tolerance: ±0.005mm • Production speed: 300-600m per • minute Fuhr GmbH – Germany Fax : +49 175 2200329

Gauder Group’s ‘GreenBow’

An advanced composite material and special aerodynamic design of the bow have been developed to minimise friction and loss and therefore to reduce the consumption of electricity. easy maintenance (it has a removable tube) and the fully closed design results in fewer bow crashes.
