Southwest Windpower 20m Guyed Tower Kit for Whisper 100 & 200 Wind Turbines

This tower kit is designed specifically for the Southwest Windpower WHISPER 100 and WHISPER 200 wind turbines. This is the most economical and user-friendly tower kit available for the Whisper wind turbines. One level, guy wire supported construction allows the use of lightweight tubing while providing plenty of strength, even in high wind conditions. With the help of a winch, beast of burden or vehicle, two people can easily erect the tower in a few hours. All that is required is the necessary tubing and the proper anchors for your type of soil. At least two people should be present to safely raise the tower.

This 65-foot (20 m) tower uses a gin pole to assist in raising the tower. The basic principle of gin pole use is described on the next two pages. This Whisper tower kit includes a galvanized base with separate pivots for both the tower and gin pole. The tower base has a footprint of 16 inches square. In many cases a concrete pad for the tower base is not necessary.

A simple extruded aluminum coupling clamp allows the use of different wall thickness of tubing, depending on site requirements. Threaded coupling points are eliminated, allowing lighter materials to be used with the same or greater strength than a threaded pipe tower. The guy wire attachment clamps onto the upper mast section. This reduces the number of pieces of tubing used to construct the tower and reduces the stresses concentrated at this point. Pre-cut and swaged guy wires eliminate wire measuring and cutting.

Site Selection

To find the best location to erect your tower and wind turbine, study the available area and take note of how the prevailing (most common) winds blow through it. If there are trees, buildings, hills or other obstructions take note of how high they are and where they are in relation to the prevailing wind direction. The best site for your tower and turbine will be upwind and above any obstructions that may exist. If there are houses or trees in the surrounding area a good rule of thumb is to mount the turbine at least 15 feet above any obstructions within 500 feet (150 m) of it.
