To minimize the visual impact of massive existing pylons, the Spindle Towers sought maximize transparency while employing graceful, slender towers.  The innovative solution splits a tower into three separate structures to support each line.  Structurally, the combination of slender individual structures became more elastic than the single shaft structure.  The repetition of slender and transparent towers  in close proximity gives a sense of visual rhythm while the slight formal variation within the repetition creates visual harmony.

Antique Spindles

The form of each tower resembles traditional weaving spindles and many parts of the world shares this traditional device  cross culturally.  The spindle towers symbolically connects the thread of electricity everywhere, delivering power in all terrains.

By supporting each line at the top center of the shaft with a separate support structure, the Spindle tower eliminates the cantilevered arms found in existing towers, thereby reducing the forces on a single tower, allowing for a structurally simpler and inherently safer design.

The Spindle Towers are economical.  As the design eliminates cantilevered loads and has primary axial loads, the forces on the spindle are minimized and thus the rigidity and strength of the spindle can be minimized.  This reduces the quantity and cost of the materials used.
