An insulating material used in bulk to wrap electrical cables or other equipment is called insulation. The term insulator is also used more specifically to refer to insulating supports used to attach electric power distribution or transmission lines to utility poles and transmission towers. perfect insulator does not exist, because even insulators contain small numbers of mobile charges (charge carriers) which can carry current. In addition, all insulators become electrically conductive when a sufficiently large voltage is applied that the electric field tears electrons away from the atoms.
From Wikipedia, the free encyclopedia. The Tabernas Desert (Spanish: Desierto de Tabernas) is one of Spain's semi-deserts, located within Spain's southeastern province of AlmerÃ­a. Almeria is the driest region of Europe, with the continent's only true desert climate where annual rainfall reaches levels as low as 156 mm in coastal areas.
Spain is separated from North Africa on the south by the Strait of Gibraltar and the Mediterranean Sea, which also washes Spain's entire east coast. The Balearic Islands lie in the Mediterranean and the Canary Islands in the Atlantic, off the coast of Africa. Spain also holds two cities, Ceuta and Melilla, on the Mediterranean coast of Morocco. Spain's perimeter is mountainous, the mountains generally rising from relatively narrow coastal plains.
