@ razpak,
I used to swear at the time, but there was a good reason for humping around heavy wooden ladders, if not using climbing spikes (on dead circuits).
High voltage gloves were so thick you couldn't even pick up a cup of tea !
The best solution was to use ordinary leather gloves so you weren't burnt, put the jumper into the bottom of the line tap and jam it on to the live line as fast as you could !
The fun part was cutting through a 3 Kv coaxial outer, even with the power off there were spectacular earth currents.
Or perhaps spiking through the return core of a large and unknown DC twin cable leaving the live intact ! After that, we decided to double spike at right angles.
That's enough of "war stories" !
Kind regards,
Walter
