- 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 does it take to grow a telephone pole? 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 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.
How much are pole trees worth?
Pine timber generally sells for less than ten cents per board foot. So, a big pine tree might be worth $30. However, on a big well-managed plantation, that could add up to significant value on a per-acre basis.
How tall is the average telephone pole?
Typical utility poles measure 30 to 60 feet for poles in residential neighborhoods, and from 60 feet to over 120 feet along major highways.
Do electric poles rot?
Core rot can occur at any time in a utility poles life and is relatively unaffected by the type of wood preservative that is used. It can be a significant cause of failure in poles treated with Creosote, C.C.A. and Pentachlorophenol.
How far are electric poles in the ground?
In fact, utility poles are buried according to a specific formula: 10% of the pole’s height plus two feet equals the appropriate depth of burial. A standard utility pole measures 40 feet, so a standard hole will go about 6 feet down into the ground.
What is the lifespan of a utility pole?
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.
Is it safe to live next to a utility pole?
Is this just an aesthetic concern or is there a real downside to living near power lines? Ranging in height from 20 to 100 feet and spaced about 125 feet apart, utility poles can lower your property values, cause damage to your home and land, and may even be hazardous to your health.
Is there any danger living near power lines?
Most scientists believe that exposure to the low-level EMFs near power lines is safe, but some scientists continue research to look for possible health risks associated with these fields. If there are any risks such as cancer associated with living near power lines, then it is clear that those risks are small.

How much weight can a utility pole hold?
The horizontal loads that the H-classification poles can hold range from 10,000 lbs. for H5 to 5,400 lbs.
What is the voltage on street power lines?
The electricity in transmission lines is transported at voltages of over 200 kV to maximize efficiency. Voltages of 220 kV to 500 kV are typical. Transmission lines are usually attached to large lattice steel towers or tubular steel poles.
How deep do electricity poles go?
Poles come in different sizes and are well marked. The marking are 10 foot from the base of the pole so expect to find them 6 foot above ground level. This is because all poles should be buried to a depth of around 4 feet in the ground.
How high are power lines from the ground?
According to the National Electrical Safety Code, telephone lines must be at least 14 feet above the ground and electrical lines must be at least 15-1⁄2 feet above the ground.
What does C mean on a telephone pole?
What does the green ‘C’ mean? This pole was not planted deep enough. It is classed as shallow, climbable.
Why do power lines have 3 wires?
A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line to ground voltage because it uses less conductor material to transmit a given amount of electrical power.
Why are power lines not insulated?
Myth 4: All power lines are well insulated. They may have weather coating, but it provides no insulation or protection from electric shock. Even insulated lines could be unprotected after being exposed to years of weather. So no powerline is completely safe to touch or approach too closely, ever.
Why do birds not get electrocuted on power lines?
When a bird is perched on a single wire, its two feet are at the same electrical potential, so the electrons in the wires have no motivation to travel through the bird’s body. No moving electrons means no electric current.
Why do telephone poles not rot?
In order to last for decades after they are sunk into the ground, wood utility poles need preservatives that fend off termites, fungi, and the elements. Not many chemicals are up to the challenge. About half the wood poles in the US are treated with pentachlorophenol, known as “penta” in the trade.
Can a human hang from a power line?
It is never “safe”, just “safer”. It can’t kill you to charge you up to 50,000 volts, it’s not a lot of current if you don’t make a path to a large conductor. You can charge yourself to thousands of volts by rubbing your feet on the carpet. So the answer is “you’ll be fine”.
Why do electricians work with one hand behind their back?
When working on high-voltage circuitry, many electricians like to place one hand behind their back because this way there is little chance for each hand to touch objects of different electrical potentials and cause a shock.
Can you touch a tree that is touching a power line?
Unless you plan on getting electrocuted, you should NOT touch, let alone prune a tree that’s in contact with power lines! Just touching a branch that’s touching a wire can cause a fatal injury.
What is the black stuff on electric poles?
All preservatives used for utility poles are approved and regularly reviewed by the U.S. Environmental Protection Agency (EPA) and the Canadian Pest Management Regulatory Authority (PMRA). Penta, Copper Naphthenate, Creosote and DCOI are oil-type preservatives and are carried into the wood via petroleum products.
How deep do you have to put a telephone pole in the ground?
Calculating the Depth of the Pole 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.
