First time ever I managed to be on site whilst a pole was being set "live line". Really good to watch the process and the number of guys involved as spotters. The one I saw was "planted" in the middle of a field with a pole lorry but same principle.
It became a terminal pole a couple of days later during the shutdown as 10 spans were undergrounded and routed via a new substation during the outage. All paid for by the customer too.
