Catenary

Catenary

Overhead power line for electric locomotives. Contrary to what some might think, the catenary is not straight, but in a zigzag shape so as to distribute the contact over the contact strip support and thereby avoid just one point from being worn. The catenary is made of copper, which has aroused the interest of copper traffickers in lines undergoing electrification.
