WPU clamps: Fastenings à la carte

WPU clamps: Fastenings à la carte

(Werdohl, July 2010)

WPU: Just three letters that describe one of the most interesting applications for STAUFF clamps. We’re talking about wind energy and the German term for wind power units (WPU). With clamps for high-power cables in wind farms, the user is able to combine individual solutions from a construction kit. In this way, customers can even design made-to-measure clamps. On a special test rig at their headquarters in Werdohl-Ehrenfeld, STAUFF is able to calculate the correct parameters for fastening the clamp bodies.

WPU clamps also ensure customised fastenings for offshore wind farms. Frank Schroeder, sales engineer responsible for the wind power industry: „For applications like these, we offer components with exceptional corrosion protection that withstand salt-spray testing over 720 hours without any problem.” In addition, a new, certified clamp type also complies with the strict regulations of the internationally applicable UL94 V-0 fire prevention regulations. „Because clamps in wind turbines are arranged one above the other, a fire would spread very quickly”, explains Ulrich Koenig, head of the R&D department. „This is prevented by using a special approved material, namely Polypropylene with fire-retardant additives.”

To simplify logistics, STAUFF also supply individual kits on request. These consist of a weather-proof pack containing, for instance, the fastening elements required for a turbine power unit. Schroeder: “This enables us to be extremely flexible when meeting customers’ requirements”.

Wind turbines also call for hydraulic filters and replacement filter elements, test couplings, hand-held hydraulic testers and laser particle counters provided by STAUFF. The entire range of products for this branch of industry will be exhibited by STAUFF at the HUSUM WindEnergy 2010 (21 - 25 September 2010), in Hall 2, Stand 2C03.
