Poles are typically set into the ground: 10% of the overall height + 2 feet, except in questionable soil conditions. Example: Overall pole height: 30 feet, the pole should be buried: 3 feet + 2 feet = 5 feet below grade, and 25 feet above grade.
How much does a steel utility pole cost?
Shipping a steel pole would be approximately $120 per pole. It is recognized by utilities that linemen prefer to work on wood poles because of greater familiarity and maneuverability, as well as the low electrical conductivity of wood.
How long does a wooden utility pole last?
Assumptions About Service Life An Electric Power Research Institute study suggested that wood poles lasted 50 years. Most utilities assume that their poles provide 30 to 40 years of service life.
What wood is used for power lines?
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.
How deep is a telephone pole buried?
The standard utility pole in the United States is about 40 ft (12 m) long and is buried about 6 ft (2 m) in the ground. However, poles can reach heights of 120 ft (37 m) or more to satisfy clearance requirements.

How long does a utility pole last?
Many utility poles are several decades old Most power poles are much older than their useful life expectancy, which is likely somewhere around 50 to 60 years. But some of them are much older. Metal and concrete poles can last much longer than wood, but eventually all utility poles need to be replaced.
How long do metal poles last?
Steel utility poles can be manufactured to the same dimensions as wooden poles but require no harsh chemical treatments. They’re often galvanized to protect them from corrosion and other harsh elements. It’s been estimated that steel utility poles can exhibit service lives of 50-80 years.
How much does a electric pole weigh?
The volume of that pole is 30 * pi * 0.5^2, so 24 cubic feet. The density of pine is ~30 lbs per cubic foot, so this hypothetical pole weighs 30 * 24 = 720 pounds. If you need something more specific, call up your power company and ask them.
How long does it take to grow a utility pole?
Most pole classes have larger diameter and height requirements than sawtimber. Growing a larger tree for poles typically requires a longer rotation (10–15 years). Longer rotations increase the time a landowner must carry establishment costs and increase the risk of severe weather damage to standing timber.
How many utility poles are replaced each year?
Steel utility distribution poles have a number of clear advantages over competing materials (treated wood and concrete). These include ease of installation, reliability, durability, life cycle cost and environmental considerations. An estimated 2.5 million wood poles are replaced annually.
How long will telephone poles last in the ground?

How long does it take to replace an electrical pole?
The average pole replacement could take up to 3-4 hours under favorable conditions with no mitigating circumstances – or longer if unforeseen circumstances slow the crew down.
How do I identify a utility pole wire?
Cable and telephone lines are located further down the pole and are directly attached to power poles without insulators. Electric lines carry high voltages and are always placed at the top of utility poles. Telephone lines and cable lines are placed lower on the poles.
Will telephone poles go away?
So, while 5G may eliminate the need to have a cable running directly into your house (and so may be the downfall of line rental charges), it will not eliminate the need to have a central, wired network in place. Accordingly, for the foreseeable future, telephone poles aren’t going anywhere.
How many wires come from pole to house?
Primary and Secondary Line The service drop leads from the utility pole lines to a home. It is made up of three conductor wires. Two of them are insulated wires that carry electricity from the transformer; the third is a bare neutral wire that connects to the grounding wire.
