Close to the junction on all sides, the tram wire turns right into a stable bar managing parallel on the trolleybus wires for around fifty percent a metre.

This wire approximates the natural path of a wire strung amongst two details, a catenary curve, thus the use of "catenary" to describe this wire or often The full procedure. This wire is hooked up to the Make contact with wire at standard intervals by vertical wires often known as "droppers" or "fall wires". It is supported regularly at structures, by a pulley, website link or clamp. The entire technique is then subjected to mechanical pressure.
