The obvious solution is to keep the cables at 400+ V AC when idle so anyone cutting them even in gloves gets 400 to 800’volts even in rubber gloves why AC because it locks human muscles tight on the current source you can’t let go then just let nature take its course. let the amps flow for a couple of minutes the problem self resolves. Put this on national news and the Darwin award winners will deter the rest. Society doesn’t need thieves they should all be put to death like in olden times anyway.
