While undergrounding of electric distribution is on the rise and already a significant fraction of line length, undergrounding of lines at transmission voltages is much less common in the U.S.
These cables may be buried directly in the ground, or may be installed in ducts buried in the ground. Concrete or metal markers are often installed at intervals to show the location of the cables.

Early undergrounding had a basis in the detonation of mining explosives and in undersea telegraph cables. Electric cables were used in Russia to detonate mining explosives in 1812, and to carry telegraph signals across the English Channel in 1850. With the spread of early electrical power systems, undergrounding began to increase as well. Thomas Edison used underground DC “street pipes” in his early electric power distribution networks; they were i
