This type of geometry can be achieved using different techniques. In this case the base curves are generated from the intersection between a surface and a set of planes perpendicular to a spine curve.
Since the wires diameter are very small, the images lose a lot of quality when resized, so here is a detail:
The complexity/variety is achieved by creating "clusters" of curves and by applying several randomization operations.
The geometries were rendered in Blender using the Eevee realtime engine.
