Utility pole

A utility pole is a column or post used to support overhead power lines and various other public utilities, such as cable, fibre optic cable, and related equipment such as transformers and street lights. It can be referred to as a transmission pole, telephone pole, telecommunication pole, power pole, hydro pole,telegraph pole, or telegraph post, depending 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 cable is routed overhead on utility poles as an inexpensive way to keep it 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 lines which carry higher voltage power between substations, and distribution lines which distribute lower voltage power to customers.

Utility poles were first used in the mid-19th century with telegraph systems, starting with Samuel Morse who attempted to bury a line between Baltimore and Washington, D.C., but moved it aboveground when this system proved faulty. Today, underground distribution lines are increasingly used as an alternative to utility poles in residential neighborhoods, due to poles' perceived ugliness.

Poles

The Poles (Polish: Polacy, pronounced [pɔˈlat͡sɨ]; singular masculine: Polak, singular feminine: Polka) are a nation and West Slavic ethnic group native to Poland. The population of Poles in Poland is estimated at 37,310,000 out of an overall population of 38,538,000 (based on the 2011 census). The preamble to the Constitution of the Republic of Poland defines the Polish nation as comprising all the citizens of Poland; ethnicity is a private matter of each citizen.

Poland's population inhabits several historic regions: Wielkopolska ("Greater Poland"), Małopolska ("Lesser Poland"), Mazovia (in Polish, Mazowsze), Silesia (in Polish, Śląsk), Pomerania (in Polish, Pomorze), Kujawy, Warmia, Mazury, and Podlasie.

A wide-ranging Polish diaspora (the Polonia) exists throughout Europe (Germany, France, the United Kingdom, Russia, Belarus, Lithuania, Czech Republic, Latvia, Ukraine), the Americas (the United States, Brazil, Canada, Argentina) and in Australia. In 1960, Chicago, in the United States, had the world's largest urban Polish population after Warsaw. Today the largest urban concentration of Poles is the Katowice urban agglomeration (the Silesian Metropolis) of 2.7 million inhabitants. Milwaukee, Wisconsin, hosts a Polish Fest; and Chicago, Illinois, "Polish Fest Chicago".
