{{Short description|World's longest span of electrical overhead line}}

The '''Ameralik Span''' is the longest [[span (engineering)|span]] of an [[electric power transmission|electrical]] [[overhead power line]] in the world. It is situated near [[Nuuk]] on [[Greenland]] and crosses Ameralik [[fjord]] with a span width of {{cvt|5,376|meters|feet}} at {{coord|64|6|18|N|51|14|16|W|display=inline,title}}.  It was built in 1993 by the Norwegian company NTE Entreprise ([[Nord-Trøndelag Elektrisitetsverk]]) and is part of a single-circuit 132 kV powerline running from [[Buksefjord hydroelectric power plant]] to Nuuk.

The span consists of four 40-millimeter diameter steel conductors, one of which is a spare. The span has a width of 190 metres and a minimum clearance of 128 metres. The [[Transmission tower|pylons]] on each side of the span carry only one conductor each and are situated on mountains 444 metres high on the north shore and 1,013 metres high on the south shore. It is designed to withstand the cold winters of Greenland, so electricity produced can reach consumers without any disturbance.<ref>[http://www.um.dk/publikationer/um/english/denmark/kap7/7-1.asp Friis PA & Rasmussen RO, "Denmark - Greenland and the Faeroe Islands - Greenland", ''Royal Danish Ministry of Foreign Affairs''] {{webarchive|url=https://web.archive.org/web/20100422235335/http://www.um.dk/Publikationer/UM/English/Denmark/kap7/7-1.asp |date=2010-04-22 }}</ref>
