Right!.. This surely wasn't in the UK?. I know they sling wires on low

higher volts...

Predominantly on lv but there were isolated instances where they're on 11kv
lines. If they are attached to 11kv circuits, the steelwork at the top of
the pole is earthed. Never on 33kv - although there are a few dual circuit
lines where multicore protection circuits are slung as a catenary beneath
the power circuits.
