Recently I was at work helping out with building up a robot installation in the workshop for testing. At a certain point I was holding a stretch of motor cable. These cables are for three phase 430 volt electric motors. These wires are also shielded. I had to strip a section to plug into a frequency inverter and ended up holding a handful of metal wires which were each slightly thicker than a strand of human hair. I think the shielding in a co-ax cable (y’know, for cable tv…) has a similair guage wire shielding woven around it (both look similair to a braided hose for hydraulics)…
Just thought you’de might like to know…
