These
4G LTE small cell nodes
are used by cell phone companies like Verizon and mounted to existing structures, like utility poles and street lamps. It helps blend them into an existing environment instead of adding more towers.
What are the canisters on telephone poles?
The barrels that look like oil drums or trash cans hanging off utility poles are called
transformers
. They’re used to lower the amount of voltage between the primary wires and secondary lines.
What are the cylinders on light poles?
Those are
splice containers
that have a POSITIVE pressure inside so that the connections wont get moisture in them. A ROLL of that huge black cable comes on a 1000′ spool, so every splice is 1000 foot away UNLESS some idiot with a back hoe digs it up or a moron with a garbage truck hangs on the line and yanks it down.
What are the round things on power poles?
Marker balls
are colorful, spherical markers placed on power lines for the safety of low flying aircraft and to protect the electrical infrastructure. They allow the electrical wires to be noticeable (especially during times of low visibility or inclement weather) thanks to their bold colors.
What is that stick on top of the telephone pole for?
On poles carrying both electrical and communications wiring,
the electric power distribution lines and associated equipment
are mounted at the top of the pole above the communication cables, for safety.
What are the 3 wires from pole to house?
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
. These lines have a voltage of 120 to 240 volts.
Who is responsible for cable line from pole to house?
A homeowner’s responsibility
for the incoming electric service usually starts where the utility companies wires are attached to the home. In the case where your meter is on a pole away from the building, your responsibility will usually start where the service wires are attached at the top of the pole.
Who owns the telephone pole?
The complication is that what you may call a “telephone” pole is actually a device that can be strung with multiple types of line: electrical wires, television cables, fiber optic wires, maybe even an antenna or two.
One utility owns the pole
, but multiple utilities use it — and each has its own way of numbering it.
What is inside a power pole transformer?
Distribution transformers consist of a
magnetic core made from laminations of sheet silicon steel (transformer steel) stacked
and either glued together with resin or banded together with steel straps, with the primary and secondary wire windings wrapped around them.
What are the gray boxes on telephone poles?
Crown Castle installs the boxes, called
small cells or nodes
, on utility poles to provide better coverage and capacity for wireless services, according to its website. These low-powered antennas form a small cell network that provide coverage and capacity in a similar way to a tower.
Why do squirrels not get electrocuted on power lines?
The answer lies in the way electricity travels. … That’s safe enough because
the air itself acts as an insulator
: the electricity won’t spark off into the space around lines. But since the lines are uninsulated that means that squirrels running on these lines are coming into direct contact with the flow of electricity.
Can a human hang from a power line?
If you are hanging from high voltage lines (tens of thousands, not hundreds), touching even a wood pole at the same time as the power line may kill you, unless the wood is
extremely dry
. Even though wood is considered a poor conductor, when it gets damp its conductivity increases dramatically.
Why do birds not get electrocuted on power lines?
Birds can sit on power lines and not get electric shocks
because the electricity is always looking for a way to get to the ground
. The birds are not touching the ground or anything in contact with the ground, so the electricity will stay in the power line.
What is the lowest line on a telephone pole?
The secondary wire (or service drop) carries lower voltage electricity from the transformer to individual electric meters.
Communication wires (telephone, cable, fiber optics)
are usually the lowest wires. Guy wires help stabilize the pole.
How do you identify a line on a power pole?
It is easy to tell power lines apart from these types of lines – power lines
are always higher up on the pole
, they always have insulators, and they do not touch other lines. Cable and telephone lines are located further down the pole and are directly attached to power poles without insulators.
How deep should a utility pole be buried?
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.
