    3-CMLT-1028-02 REV D Introduction This tower kit is designed specifically for the Southwest Windpower Skystream 3.7® and Whisper 500 wind turbine. To our knowledge this is the most economical and user-friendly tower kit available for the Skystream 3.7® and Whisper 500 wind turbine. The tower kits are designed to use guy wires, allowing the use of schedule 40 pipe while providing adequate strength, even in high wind conditions.

  • Page 4: Safe Installation

    SOUTHWEST WINDPOWER 3-CMLT-1028-02 REV D Safe Installation Safety is the most important consideration to take into account when installing a tower and wind turbine. It is very important to remember that any wind turbine has high speed spinning parts and can be very dangerous if not installed properly! Make sure that the Schedule 40 steel pipe used for the tower is of adequate strength, that all bolted connections are tight and the guy wire anchors are suitable for your soil conditions.

    2. Parts NOT included in the Tower Kit must be procured locally, and should be available at a hardware store. Pipe for the tower can be purchased from a local plumbing or steel supplier. Southwest Windpower can help you find sources for lift lines, pulleys, and anchor eyebolts.

  • Page 8: Step 1: Site Selection

    Due to the high cost of shipping and the widespread availability of pipe used for the tower, Southwest Windpower does not provide these materials. Materials are readily available through most hardware stores or plumbing companies and will cost much less when purchased locally than if they were shipped from our factory.

    SOUTHWEST WINDPOWER 3-CMLT-1028-02 REV D Isometric View Figure 2: Anchor and cable layout Step 3: Tower, Base and Anchor Layout This tower kit must only be erected on a calm day (no wind). The tower base and anchors should be laid out as described in Figure 2 and Figure 7. The tower will be assembled laying on the ground and then tilted up into position.

In this case the two opposing anchors should be at the same height on the hill as the tower base, one anchor should be directly uphill and one directly downhill from the tower base.

A hole must be dug in the ground at the desired anchor point. The calculations made for this manual and anchor design are for clay soil, which is the worst-case scenario.

    SOUTHWEST WINDPOWER 3-CMLT-1028-02 REV D Step 5: Assembly of Pipe sections The following steps have been taken before you reach this point: 1. You have dug 5 holes. Four Anchor holes and one base hole. You have made sure they are centered and at equal distances from the center hole.

    SOUTHWEST WINDPOWER 3-CMLT-1028-02 REV D The last hole to be drilled is the one in the gin pole that connects it to the steel anchor links (see Figure 4.2). This hole cannot be drilled until the anchors are in place and the assembled gin pole is bolted to the base angles.

The table in this section tells you how long to cut these cables and also how long the approximate cable length should be after being attached to the turnbuckle and the tower pipe.

  • Page 28: Step 7: Grounding The Tower

    SOUTHWEST WINDPOWER 3-CMLT-1028-02 REV D Step 7: Grounding the Tower It is critically important that the tower be properly grounded before it is erected. Grounding will provide static and lightning protection for the turbine, tower, and the rest of your system.
  • Page 29 SOUTHWEST WINDPOWER 3-CMLT-1028-02 REV D This is the rope that will eventually be used to raise the tower pipe. This rope should be around 60 feet long and must have a minimum breaking strength of 8000 lbs. The slack length of this rope should allow the gin pole to rotate just past vertical.
  • Page 30 SOUTHWEST WINDPOWER 3-CMLT-1028-02 REV D 8. Move the vehicle to the other side of the tower and prepare it to begin pulling on the tower lift line. Be sure the tower lift line goes through a pulley on the anchor and is then securely attached to the vehicle.
  • Page 31 SOUTHWEST WINDPOWER 3-CMLT-1028-02 REV D 15. Install the turbine to the top of the tower by following the instructions in the wind turbine owner’s manual. The electrical wires for the wind turbine should be installed inside the tower pipe. Double check the rotor blades, tail, and tower insert are properly secured to the turbine and tower.
