It is like the poles ID tag for their system, it usually will refer to that particular pole's number, depending on what is on the pole it can refer to the equipment that's on the pole like a switch, so they know exactly what switch they will be operating, it could also refer to fuse size (ex.
How old is my utility pole?
Despite the preservatives, wood poles decay and have a life of approximately 25 to 50 years depending on climate and soil conditions, therefore requiring regular inspection and remedial preservative treatments.
What is a Class 6 power pole?
The Class 6 poles are 20 to 45 feet in length and a minimum of 17 inches in circumference at the tip. This drops incrementally down to the smallest classification. Class 10 poles are 20 to 25 feet in length and a minimum of 12 inches in circumference at the tip.
How old is a telephone pole?
Most utility poles are 50 to 60 years old — with some of them much older than that! Depending on your local climate, wood telephone poles in your area may last from 40 to 60 years. Metal and concrete poles can last much longer, but eventually all utility poles need to be replaced.
What are the 3 power lines?
Below the static line are three power lines called transmission lines. Transmission lines get typically labeled "A," "B," and "C," and called the "A-B-C Phase." They conduct high voltage electricity from power plants to substations.
What are the different lines on power poles?
Utility poles are commonly used to carry two types of electric power lines: distribution lines (or "feeders") and subtransmission lines. Distribution lines carry power from local substations to customers.
Which power lines are which?
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.
What are the different lines on a power line?
Telephone and cable wires are typically the lowest wires. Transformers convert higher voltage electricity carried by primary wires and lowers the voltage for use by customers. Guy wires help stabilize utility poles. A ground wire runs the entire length of the pole.
How do you identify a power line?
To determine if your line is three-phasethree-phaseThe conductors between a voltage source and a load are called lines, and the voltage between any two lines is called line voltage. The voltage measured between any line and neutral is called phase voltage. For example, for a 208/120 volt service, the line voltage is 208 Volts, and the phase voltage is 120 Volts.https://en.wikipedia.org › wiki › Three-phase_electric_powerThree-phase electric power - Wikipedia or single-phase, first look for wood poles—often called a telephone pole or utility pole. All distribution lines, whether three- or single-phase, are mounted on wood poles. Metal poles carrying electrical wires are transmission lines.
What is a pole number?
The number of pole pairs (p) or number of poles for an asynchronous motor determines the motor's synchronous speed: Two-pole and four-pole asynchronous motors are typically used for centrifugal pumps. The rotational speed of these motors can be varied using frequency inverters.
What does the class of a pole mean?
The classes' definition specifies a minimum circumference that depends on the species of tree and the length of the pole. This circumference is measured 6 feet from the butt of the pole. For example, a class 1 pole has a minimum top circumference of 27 inches.Jun 6, 2014
How much is a telephone pole worth?
Cost: From $350 to $1,800. That's just the pole. Add in labor and equipment costs, and it can cost as much as $3,000 to replace a pole that has been knocked down by, say, a storm or a car. And why not bury the transmission and distribution lines?
How do I find where my power lines are?
Anyone who plans to dig should call 811 or go to their state 811 center's website before digging to request that the approximate location of buried utilities be marked with paint or flags so that you don't unintentionally dig into an underground utility line.
How are the poles numbered?
The odd numbers would be on the North side of the street. eg: 3-1, 3-3, 3-5 would be on the north side or the west side. A crew may be sent to Pole number 3-3, Oak Street.
What is the size of a power pole?
about 40 ft
Why are there 3 power lines?
Because they carry 3-phase alternating current. When there are just 3 cables, the circuit is closed by ground. When there are 6 cables, it is a double-circuit power line. When there is a 4th cable, that is the ground cable and it is above the others, to protect them from lightning.
How old is the average telephone pole?
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.Sep 8, 2016
How do I know if I have 3-phase power lines?
A 3-phase power supply has a switch that controls the flow of electricity through 3 circuits, so there are 3 poles. Check for 2 wires for a single-phase or 3-4 wires for a 3-phase. In a single-phase circuit, there's 1 live wire and 1 neutral wire. In a 3-phase circuit, there are 2 or 3 live wires and 1 neutral wire.
How tall is a power line pole?
Utility Pole Poles range from 20-100 feet tall; the standard pole is 35 feet tall. Popular pole trees include Douglas fir, Southern pine, and Western red cedar. Poles are buried about 6 feet in the ground and spaced about 125 feet apart. The wood pole's lifespan is about 30-40 years.
What are the lines on power lines?
Primary wires are on top of the pole and usually carry 12,000 volts of electricity from a substation. Insulators prevent energized wires from coming in contact with each other or the utility pole. Cutouts act like a fuse and open when there is a problem with the line or a section of it.
