Not all the towers along a transmission line are identical. Look closely at a tower where the line makes a sharp turn and you will likely find it is wider and beefier than other towers along the route. The added strength and weight are needed to resist the unbalanced pull of the conductors, which might overturn an ordinary tower. These special towers are called deviation or angle towers.
The transmission-line tower everybody knows is an Erector Set latticework of steel girders and diagonal braces. The techniques for designing and building these towers are the same ones used in constructing steel bridge trusses or crane booms. The individual pieces can be made cheaply from rolled steel and then bolted together on the site. This last point is more important than it might seem: transporting a fully assembled tower 100 feet tall is an awkward and expensive business.
Some time ago, a friend insisted that people should not listen to practicing architects or read what they write. According to him, the lack of logic in our discourse, the incongruity of our words, and the overzealousness in readings brought about by the biographical revision of our work were of little value.
In his book The Eyes of the Skin, Juhani Pallasmaa approaches it from the opposite direction, but ultimately gives the same advice:
The verbal statements of artists and architects should not usually be taken at their face value, as they often merely represent a conscious surface rationalization, or defense, that may well be in sharp contradiction to the deeper unconscious intentions giving the work its very life force.
