Power poles

A utility pole is a column or post used to support overhead power lines and various other public utilities, such as electrical cablefiber optic cableand related equipment such as transformers and street lights. It can be referred to as a transmission poletelephone poletelecommunication pole, power polehydro pole[1] telegraph poleor telegraph postdepending on its application.

A stobie pole is a multi-purpose pole made of two steel joists held apart by a slab of concrete in the middle, generally found in South Australia. Electrical wires and cables are routed overhead on utility poles as an inexpensive way to keep them insulated from the ground and out of the way of people and vehicles. Utility poles can be made of wood, metal, concrete, or composites like fiberglass. They are used for two different types of power lines: subtransmission lineswhich carry higher voltage power between substations, and distribution lineswhich distribute lower voltage power to customers.

The first poles were used in by telegraph pioneer William Fothergill Cookewho used them on a line along the Great Western Railway. Utility poles were first used in the midth century in America with telegraph systems, starting with Samuel Morsewho attempted to bury a line between Baltimore and Washington, D.

Today, underground distribution lines are increasingly used as an alternative to utility poles in residential neighborhoods, due to poles' perceived ugliness. Utility poles are commonly used to carry two types of electric power lines : [2] distribution lines or "feeders" and subtransmission lines. Distribution lines carry power from local substations to customers. They generally carry voltages from 4. A service drop carries this lower voltage to the customer's premises. Subtransmission lines carry higher voltage power from regional substations to local substations.

They usually carry 46 kV, 69 kV, or kV for distances up to 60 miles. Transmission lines carrying voltages of above kV are usually not supported by poles, but by metal pylons known as transmission towers in the US. For economic or practical reasons, such as to save space in urban areas, a distribution line is often carried on the same poles as a subtransmission line but mounted under the higher voltage lines; a practice called "underbuild".

Telecommunication cables are usually carried on the same poles that support power lines; poles shared in this fashion are known as joint-use poles, but may have their own dedicated poles. Joint-use poles are usually owned by one utility, which leases space on it for other cables. Most utility poles are made of wood, pressure-treated with some type of preservative for protection against rot, fungi and insects.

Southern yellow pine is the most widely used species in the United States; however, many species of long straight trees are used to make utility poles, including Douglas firjack pinelodgepole pinewestern red cedarand Pacific silver fir. Traditionally, the preservative used was creosotebut due to environmental concerns, alternatives such as pentachlorophenolcopper naphthenate and borates are becoming widespread in the United States. 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.

Other common utility pole materials are steel and concrete, with composites such as fibreglass also becoming more prevalent. One particular patented utility pole variant used in Australia is the Stobie polemade up of two vertical steel posts with a slab of concrete between them.

In southern Switzerland along various lakes, telephone poles are made of granite. Starting in the early s, these foot 5 m poles were originally used for telegraph wires and later for telephone wires. Because they are made of granite, the poles last indefinitely. 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.I saw a power pole the other day and it had 5 crossarms on it with wires.

What does that mean, is there additional voltages on each tier. OK the top wires on power lines are the hot wires meaning there is power flowing through them. There are two or three wires depending on what phase that pole is on three phase-three wires, one phase- two wires.

The phases are the locations of wires in the generator back at the power plant. They are always degrees apart from each other phase. They can be different voltages. For example, a single phase pole will be set for volts. One wire carries volts and the other carries volts. The voltages for three phase are volts, and volts. The wire directly below the hot wires is your neutral or grounded wire. Power needs a path back to the generator after going through a load like a house, school, or Industry.

The pole line down your street, if typical, has the primary at the top and the neutral below. Below the neutral can be almost anything: if it is a triplex or a twisted pair, it probably feeds adjoining power drops buildings or streetlights from a transformer on a nearby pole. There can also be telephone, cable television, and other services in any order below the neutral.

It would be difficult to figure out the 5-crossarm arrangement you mention without much more detailed information.

If it is at a street intersection, it probably carries lines that go in several directions. For much more information including pictures and diagrams, try an internet search on "electrical distribution. You are all wrong. The top most wire is a ground or earth as the British say. The ground protects the high voltage lines below it from lightening strike. The top wire bleeds off electrical potential during storms and takes those electrons to earth before enough potential can be built up for a lightening bolt to strike.

If a strike occurs it hits the high overhead earth cable and goes to earth. The order is the highest voltage will be on the topmost layer, next the second higher voltage, the distribution line voltage, the secondary voltage, then the low voltage that goes to the residences.

If the pole you had 5 cross-arms, there must be different sets of voltages to be installed on it.

The two or one if any wires below your neutral wire are the phone or cable hard lines.

Bill Goldeen.An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy across large distances.

It consists of one or more conductors commonly multiples of three suspended by towers or poles. Since most of the insulation is provided by air, overhead power lines are generally the lowest-cost method of power transmission for large quantities of electric energy. Towers for support of the lines are made of wood either grown or laminated, steel or aluminum either lattice structures or tubular polesconcrete, and occasionally reinforced plastics. The bare wire conductors on the line are generally made of aluminum either plain or reinforced with steel or composite materials such as carbon and glass fiberthough some copper wires are used in medium-voltage distribution and low-voltage connections to customer premises.

A major goal of overhead power line design is to maintain adequate clearance between energized conductors and the ground so as to prevent dangerous contact with the line, and to provide reliable support for the conductors, resilience to storms, ice loads, earthquakes and other potential damage causes. Overhead power transmission lines are classified in the electrical power industry by the range of voltages:. The overhead transmission line is generally categorized into three classes, [4] depending on the length of the line:.

This categorization is mainly done for the ease of performance analysis of transmission lines, by power engineers. Structures for overhead lines take a variety of shapes depending on the type of line. Structures may be as simple as wood poles directly set in the earth, carrying one or more cross-arm beams to support conductors, or "armless" construction with conductors supported on insulators attached to the side of the pole.

Tubular steel poles are typically used in urban areas. High-voltage lines are often carried on lattice-type steel towers or pylons. For remote areas, aluminum towers may be placed by helicopters.

Each structure must be designed for the loads imposed on it by the conductors. Where conductors are in a straight line, towers need only resist the weight since the tension in the conductors approximately balances with no resultant force on the structure. Flexible conductors supported at their ends approximate the form of a catenaryand much of the analysis for construction of transmission lines relies on the properties of this form.

A large transmission line project may have several types of towers, with "tangent" "suspension" or "line" towers, UK towers intended for most positions and more heavily constructed towers used for turning the line through an angle, dead-ending terminating a line, or for important river or road crossings.

Depending on the design criteria for a particular line, semi-flexible type structures may rely on the weight of the conductors to be balanced on both sides of each tower. More rigid structures may be intended to remain standing even if one or more conductors is broken. Such structures may be installed at intervals in power lines to limit the scale of cascading tower failures.

Foundations for tower structures may be large and costly, particularly if the ground conditions are poor, such as in wetlands. Each structure may be stabilized considerably by the use of guy wires to counteract some of the forces applied by the conductors. Power lines and supporting structures can be a form of visual pollution. In some cases the lines are buried to avoid this, but this " undergrounding " is more expensive and therefore not common.

For a single wood utility pole structure, a pole is placed in the ground, then three crossarms extend from this, either staggered or all to one side. The insulators are attached to the crossarms. For an "H"-type wood pole structure, two poles are placed in the ground, then a crossbar is placed on top of these, extending to both sides. The insulators are attached at the ends and in the middle. Lattice tower structures have two common forms. One has a pyramidal base, then a vertical section, where three crossarms extend out, typically staggered.Power Poles are small towers or attachments that can be used to extend the range of Power Lines and to transfer power from buildings that produce power to buildings that consume it.

Ground Power Poles can be placed on regular ground but will also snap to foundations. Higher marks of Power Poles are unlocked in the Caterium Research tree. Each Power Pole can handle an unlimited amount of power passing through it. Power Poles can be linked together with a Power Line for up to meters apart. It is recommended to leave at least one spare connection on each Pole for lines coming from and going to other poles.

There are currently 3 marks of Power Poles available, distinguished by ingredients, connections, and height. Sign In. From Satisfactory Wiki. Jump to: navigationsearch. Power Pole Can handle up to 4 Power Line connections.

Although Goku uses it primarily as a weapon, its true purpose is to use its size-changing ability to travel from Korin Tower to The Lookout. Much like how it's used to connect from one location to another, the stick was originally a measuring rod used by Da Yu of the Xin Dynasty in order to measure the depth of the flooding waters.

Though with each test run and several other attempts before his visit, several if not any weapon offered to monkey king broke under his sheer strength much to the monkey's chagrin. Since then, the staff has been in the monkey king's possession ever since.

The Power Pole is first seen in Chapter 1 of the Dragon Ball manga and is used to inspect Bulma and her capsule vehicles. Goku stated that it was given to him by his deceased grandfather, Gohan. Korin mentioned in the episode " Lost and Found " that he had given the Pole to Master Roshi when he had climbed Korin Toweron his request.

Korin did not think anyone else would be qualified to use the weapon; though restrictions to wield the pole are unknown. Master Roshi likely gave it to Grandpa Gohan before it was handed down to his adopted grandson Goku. As seen in the chapter "Carrot Top" and the episode " Boss Rabbit's Magic Touch ", the Power Pole is capable of extending to the moon if its user wills it. This can be justified by the fact that Goku was hungry and was unable to concentrate.

It is a powerful weapon, and can never break; it can easily break a sword as shown when it broke Ninja Murasaki 's sword, and Tao's sword in half. Goku also uses it during his final confrontation against King Piccoloand later in order to get to Kami's Lookout.

It can also be utilized by the user without him actually having to touch it, as evidenced by how Goku managed to catch the young thief who stole most of his gear during the Red Ribbon Army Saga and retrieve everything besides the Dragon Radar due to the thief selling it to a pawn shop earlier.

After the 23rd tournament, Goku uses the pole to fight Annin in the final episode of Dragon Ball. In the Garlic Jr. Sagathe pole is not between Korin Tower and Kami's Lookout but in Korin's possession, as seen when he bets it in a poker game with Maron and Yajirobe. Wheelo's fortressGoku uses the Power Pole again in the battle with Dr. The pole is gold when it is small and can come to Monkey Boy whenever he whistles. It retracts when Monkey Boy spins it around. Grandpa Gohan seems to have a pole similar to the Power Pole in his possession in the live action movie: Dragonball: Evolution.

Grandpa Gohan is seen using his pole only in battle. It is unknown if the pole he possesses has the same abilities as the one seen in both manga and anime.We work to deliver our promises to the UK utility and telecom sector and continue to create innovative solutions within our supply chain.
