Power Line Generator builds complete overhead lines inside Blender: a German Danube pylon line with quad bundles and glass insulator strings, a British barrel tower line, a US wooden utility pole street with transformers and cobra-head lights, a Japanese urban pole, an Asian cable tangle, a historic telegraph line, or the overhead catenary of a main line railway, a high-speed line, a tram or a trolleybus street. Pick one of 37 designs, then change anything: every part is a number, a choice or a switch, and the line rebuilds live as you drag.

The cables hang the way real ones do. The sag is solved as a true catenary from the ruling span, so longer spans hang lower, spans on slopes hang between supports at different heights, and the panel shows the ground clearance.

Run the line straight, along any curve you draw, or string it between objects you already have. Pick a terrain object and every support stands on the ground while the wires sag over the hills.

One click, a new line
Pick a design in the sidebar and the whole line rebuilds: towers, insulators, bundles, earth wires and the sag between them.

Pylons from around the world
Danube, barrel, Christmas tree, cat-head, guyed-V, UHV, Japanese four-circuit, Soviet portal, steel monopole and wooden H-frame.

Poles, streets and railways
US, UK and European distribution poles, Japanese and Asian city poles, a telegraph line, railway catenary, tram and trolleybus wires.

Real catenary sag
Drag the sag and every span hangs lower as a true catenary; the panel shows the sag in meters and the ground clearance.
