Whisper Guyed Tower Kits
This tower kit is designed specifically for the Southwest
Windpower Whisper 500 wind turbine and the Skystream 3.7. To our knowledge this is the most
economical and user-friendly tower kit available for the Whisper wind
turbines. The tower kits are designed to use guy wires, allowing the use of
5” schedule 40 pipe while providing adequate strength, even in high wind
conditions. At least two people should be present to safely raise the tower.
Southwest Windpower
offers tower kits that are easy and safe to install. A number of heights are
available. None of our towers require any kind of welding or machining. Only
the largest towers may require excavation and concrete work. Most designs
can be installed within a few hours to a day. You will NEVER need to climb a
tower.
All of Southwest
Windpower’s guyed tower kits include everything you need with the exception
of:
1) Pipe material
2) Anchors
3) Power wires
To keep your costs low
and to consider site variables, these components should be purchased
locally. When selecting the materials for the construction of your tower,
please consider the following:
- Pipe
Material: For most conditions, we recommend a “schedule 40” pipe
material. This offers a wall thickness of .125” which is strong enough to
resist most wind conditions. If you are using fence pipe material, make
sure you ask for “SS40”. If you live in an environment were your winds
will never exceed 80 mph (140 km) then we suggest using a thinner wall
material such as a “schedule 20”. In conduit material, this is called
“SS20”.
- Anchors: The anchors
are by far the most difficult part of installing a tower. Once you have
them in the ground, a tower installation gets really easy. There are
various soil materials that you should consider prior to installing your
tower. The type of anchor should also vary. Our owner manuals have
recommendations based on soil type.
- Power wires: Because
of the size of turbine and variable length from the turbine to your
batteries/inverter, it is impossible to know the proper wire size. Once
you have understood the distance from the turbine to the battery, refer to
the wind turbine’s owners manual for the proper wire size. Be sure to
select the right type of wire for your environment.
VERY IMPORTANT:
Prior to the installation of your tower, read the owners manual thoroughly
and make sure you understand the environmental conditions at your site prior
to purchasing materials. We offer manuals that are free to download and
review prior to purchase.
While Southwest
Windpower recommends our tower kits as a reliable option for all wind
turbines, you may also source your own tower by using the proper manual
(above) and
Thrust load information on Whisper towers for accurate specifications.
