Yes, my vote would a controls cable of some type (Profibus / Interbus / CAN / etc). Or maybe a (simpler) temperature and or brake wiring?I hadn’t thought of it, but that green cord could be just that, green.
Control feedback cable?

Like Kwired asked - I wonder what it is exactly that we are looking at?
Yeah I've done some large PV systems where the designer was a green wire cult member. everything already had a wire EGC, but then there was this other green wire that went around and bonded equipment, cable tray etc again.I have seen this done in a few industrial situations where grounding is critical and a "supplemental" ground is run to equipment in addition to the equip ground in the wiring method.
Seen quite a few on natural gas facilities for such reason. I’ve asked questions as to why it’s there, when it already has a EGC in the cable and conduit is attached with a bonding jumper to the cable tray, which in return is connected to the station grounding grid.
