From an article on ControlDesign.com:
It was like the Egyptian obelisk going up in “The 10 Commandments,” only it was a lot faster, and the slaves were replaced by portable hydraulics. Oh, and there was a 32 ft diameter fan at the top.
This was the scene on a sunny, early-September afternoon as Wago installed a 100 ft tall wind turbine next to its U.S. headquarters in Germantown, Wis. And, as if the gleaming white tower wasn’t impressive enough, it was “tipped up” in an amazing 8-10 minutes by a portable hydraulic unit hooked up right next to the tower. After that, it took only another 15 minutes to bolt down the tower, hook up its electronics, and get it spinning in the breeze of Wisconsin’s famous “dairy air.”
Capable of generating 20 kW for Wago’s multi-function facility, the small-scale, commercial-grade VP-20 turbine was built by Renewegy in nearby Oshkosh, Wis. The turbine employs Wago’s 787 Series power supplies, 756 Series cables/connectors, 288 Series fuse blocks and backup capacitor module.
The wind turbine’s initial cost was $80,000, but state and federal incentives allow Wago to reduce its bill by about $35,000. Other VP-20s have been installed at SCA Tissue in Neenah, Wis., and at the North Texas Job Corp Center in McKinney, Texas. Renewegy reports that it can install single 20 kW units on farms, 40 kW dual units to serve schools, and 100 kW five-unit systems for small wind farms and commercial applications.
