What is the size of the pole in the electricity distribution ? 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.

- First the power poles. 30 and 35 foot poles are set 6 foot deep. Add an extra 1/2 foot for every 5 foot of pole above 35 foot. My preference around the farm is underground. All it takes is to be involved with one electrical accident on a farm and you will never want overhead around bins and barns ever again.

How Deep are telephone poles burried? Best Answer: A 20 foot pole set in firm soil goes in 4 feet. A 40 foot pole, 5 1/2 feet get buried. A 50 footer in 6 1/2 feet. Tops out at 8 feet buried for an eighty foot tall pole. That's for firm soil. Rocky soil is a bit shallower. Talk to your power provider before doing any digging around power poles.

Mariana Trench: The Deepest Depths The ocean's second-deepest place is also in the Mariana Trench. The Sirena Deep, which lies 124 miles (200 kilometers) to the east of Challenger Deep, is a bruising 35,462 feet deep (10,809 m).he Mariana Trench was created by the process that occurs in a subduction zone, where two massive slabs of oceanic crust collide. At a subduction zone, one piece of oceanic crust is pushed and pulled underneath the other, sinking into the Earth's mantle, the layer under the crust.

Kola Superdeep Borehole In actuality, the Kola Superdeep Borehole consists of several holes branching from one central hole. The deepest of these, named SG-3, measures just nine inches in diameter but extends 12,261 meters (or 7.5 miles) into the Earth. That's roughly a third of the way through the Baltic continental crust.

By comparison, Mount Everest stands at 29,026 feet (8,848 m) above sea level, meaning the deepest part of the Mariana Trench is 7,044 feet (2,147 m) deeper than Everest is tall.

Depth Requirements for Buried Electrical Cable Bury UF cables 24 inches below the soil surface, and 18 inches deep when protected by 2 inches of concrete. For all other applications, the burial depth is the same as specified for conduits, except that conduits are required for UF cables in 2 inches of solid rock.

- How deep should a gas line be buried? We have a natural gas line going from our meter (at one end of our house) to the back of our detached garage (opposite end of our house, but behind that end). I have no idea of the path of that line, and I may have to level an 18'x18' patch of our our back yard to place an above ground pool.

- Answer: Safe burial depths vary and should be calculated. In lieu of calculations AWWA says that for an embedment soil with an E’ of 1000 psi and no surface water, HDPE pipes with DR’s ranging from 7.3 to 21 can be safely buried from a depth of 2 ft to 25 ft where no traffic load is present and from 3 ft to 25 ft where H20 live load is present.

Fence Posts How and How Deep? Report Abuse. As a general guide, 20% of the post should be underground. You will need to increase this if there are fencing panels, or an exposed site, or soft ground. Safely reduce if the posts are holding training wires, or the ground is firm or the site is sheltered from the wind. set the posts dry by digging the post hole (about 3 feet in my area). With 7' above ground that would mean 10 foot posts. Add a shovel full of 1 or 1-12' crushed stone to the bottom drop in the post level & ram crushed stone around the post.

How Long Would It Take To Drive To The North Pole? The North Pole sits in the middle of the Arctic Ocean, on water that is almost always covered with ice. The ice is about 2-3 meters (6-10 feet) thick. The depth of the ocean at North Pole is more than 4,000 meters (13,123 feet).

- There is a 9.1km borehole in Germany, part of the Continental Deep Drilling Project (KTB), but deeper still is the 12.25km Superdeep hole in the Kola Peninsula near the Arctic Circle in Russia, drilled between 1977 and 1989. The latter is roughly 0.4% of the distance (2,900km) to the core of the earth.

How Deep to Dig Fence Post Holes Panel Post Depth. The minimum depth that you should dig your fence post holes for panel sections is 2 feet. A general formula is to dig the holes one-third to one-half of the post's aboveground height. The deeper you dig the holes, the more stability your fence has, but you must also purchase longer posts. Many builders use 8-foot posts and bury them about 2 feet deep in concrete, leaving a small margin for trimming the tops of the posts to the finished height after the posts and/or the fence panels are installed.

How deep is an underground electric line buried? This is usually a 120/240-volt service for a residential or small commercial consumer. These wires are buried in a trench 24 inches deep when installed, measured from the top of the conduit or service wire to the top of the trench. Primary service wires are the wires or distribution circuit on the high voltage side of a transformer. This is usually a 7,200/14,000-volt service for a large commercial or industrial consumer. These wires are buried in a trench 30 to 36 inches deep when installed, measured from the top of the conduit or service wire to the top of the trench. Due to erosion, service wires may not be as deep as when they were installed.

Why most cities donât bury power lines A 2010 study (pdf) found that the D.C. area could prevent more than 1,000 outages a year by burying all of its overhead lines. But it would cost $5.8 billion, adding $226 to customers' monthly electricity bills for the next 10 years. Even a partial plan that would bury just some of the lines, and eliminate 60 percent of outages, would cost $1.6 billion. As it turns out, D.C. isn't exceptional in this regard. The U.S. Energy Information Administration has just released a primer on the cost of burying power lines across the country.

How deep a hole for 21' pole? Here, a 10 foot dish on a 21 foot pole would not be needed, but if used would need to be 6 to 7 feet in the ground with the biggest glob of concrete at the botton to get below the frost line. Very little concrete above 2 feet to the surface so the frost could not push it up out of the ground.

Why most cities donât bury power lines In some regions, it's almost as cheap to bury lines as it is to string them from poles. In other areas, the cost of underground wires is much, much higher: On average, EIA found, underground lines can cost five to ten times more to build, per mile, than overhead lines.
