Poles, from which these buildings get their name, are natural shaped or round wooden timbers 4 to 12 inches (100 to 300 mm) in diameter. [4] The structural frame of a pole building is made of tree trunks, utility poles, engineered lumber or chemically pressure-treated squared timbers which may be buried in the ground or anchored to a concrete slab.
For a single wood utility pole structure, a pole is placed in the ground, then three crossarms extend from this, either staggered or all to one side. The insulators are attached to the crossarms. For an "H"-type wood pole structure, two poles are placed in the ground, then a crossbar is placed on top of these, extending to both sides.
In many places, as seen in the illustration, providers of electricity, television, telephone, street light, traffic signal and other services share poles, either in joint ownership or by renting space to each other. In the United States, ANSI standard 05.1.2008 [19] governs wood pole sizes and strength
Twenty-one trees, including an 80-year-old oak, were cut to stumps to install a 100-foot tall power pole in the front yard of Michael and Diane Olson of De Soto. “It was the centerpiece of our yard.
A pin insulator is a device that isolates a wire from a physical support such as a pin (a wooden or metal dowel of about 3 cm diameter with screw threads) on a telegraph or utility pole. It is a formed, single layer shape that is made out of a non-conducting material, usually porcelain or glass. It is thought to be the earliest developed ...
In the United States ANSI standards and RUS bulletins both direct pole embeddment for most conditions as 10% of a poles length butt to pole top +2 foot (i.e. a 40 foot tall pole would be set 4 + 2 or 6 foot while an 80 foot tall pole would be set at 8 + 2 or 10 foot).
The Ford hit a wooden utility pole and the Dodge struck the side of a building. Both the front passenger of the Dodge and the driver of the Ford were pronounced dead at the scene, while the driver ...
Wood is a material which is limited in use in high-voltage transmission. Because of the limited height of available trees, the maximum height of wooden pylons is limited to approximately 30 m (98 ft). Wood is rarely used for lattice framework. Instead, they are used to build multi-pole structures, such as H-frame and K-frame structures.
