- The typical utility pole runs about 40 feet in length, of which 6 feet is buried in the ground.
- In urban environments they are commonly spaced about 125 feet apart, while in rural areas the distance is more like 300 feet.
- (Both distances and pole height vary greatly depending on local terrain and clearance needs.)
Thus, How long do concrete poles last? Many builders and experts cite 40-60 years to be on the safe side, but if the owner of a pole barn keeps up with all of the necessary structural upkeep, the building will likely outlast the 40-60 year pole barn lifespan.

How much weight can a telephone pole hold? First a little about wood poles: A #1 pole will support the most weight, a #10 the least. The test for a #5 pole is that it must support 1900 lbs. applied two feet from the top and pulled at a horizontal angle. If it does it passes the test–but when installed in the field it is only permitted to support 475 lbs.
What kind of wood is a telephone pole made from? For Tree Farmers, utility poles have the potential to provide an excellent return on investment. Southern yellow pines and Douglas fir are the most popular trees due to their size, but Northeastern red pine, Western red cedar and other softwoods that grow tall and straight are also used.
What is stronger wood or concrete?
Concrete tends also becomes stronger over time, further fortifying the structure. In comparison, wood is less dense and thus, less durable. Another advantage of concrete is that it can be manipulated to any desired strength and casted on site, thereby making it an economical choice.
Are telephone poles concreted?
Poles are manufactured with prestressed 7-wire strands, deformed reinforcing bars, galvanized helical reinforcing wire and high-strength concrete.
How do you preserve telephone poles?
Preserving Processes Most poles are preservative treated with the entire pole placed in a pressure cylinder during processing. But some Western Red Cedar poles may only have the butt, or lower portion of the pole, treated with preservatives.
Are telephone poles still treated with creosote?
Chemical treating of wood poles is one of the last remaining uses of penta and creosote – 43% of all poles are treated with penta; 42% of all poles are treated with arsenic; and 13% are still treated with creosote. The use of penta is prohibited in 26 countries around the world, but not in the United States.
How strong is a telephone pole?
Utility poles power lines can carry more than 100,000 volts. The amount of voltage carried along electricity wires – which are also called “conductors” – can range from a few thousand volts to more than 100,000 volts.
What’s the black stuff on telephone poles?
The utility or telephone poles coated with a dark brown or oily substance –penta or creosote– give off a petroleum odor. Other poles appear lighter, sometimes greenish, in color with no odor. These are treated with arsenicals.
Which pole has longer life?
2. Steel poles: The steel poles are often used as a substitute for wooden poles. They possess greater mechanical strength, longer life and permit longer spans to be used.
What length of pole is buried in ground?
Setting depth of poles is 1/6 part of the length of pole. The depth for most heavy poles should be at least two feet. Another rule of thumb is that the hole’s depth should be 1/6 of the length of the poles and below the frost line.
Why do they use wood for electrical poles?
Despite storm damage, wooden poles remain popular with utility companies because they are affordable, lighter and easier to transport than steel or concrete poles, they don’t rust, are easy to climb and are non-conductive, which makes them safer for utility workers. Wood poles also have environmental advantages.
What are the three types of poles?
They can be divided into three types namely; Tangent distribution poles, guyed distribution poles, and self-supporting distribution poles.
What are the disadvantages of steel poles?
- Worse in salty areas, such as near beaches, as the salt can eat away at the steel.
- Not suitable for areas where the overhead service lines need to run high as steel poles are often shorter than timber.
How much does a steel pole weigh?
The average steel distribution pole (40 foot, Class 4) weighs approximately 450 pounds, and is at least 30 percent lighter than a wood pole.
Which is better pole barn or steel building?
A steel frame barn’s construction style sees steel columns anchored to a concrete foundation. This makes construction easier and more durable than the pole barn method. A steel frame barn is also weather resistant, to both inclement weather and minor weather-related damage, such as mold, cracking and rotting.
