Here are five of the six insulators removed. They are fastened with hemp, which due to its drieness make the insulators quite easy to get off the massive, square section iron hooks. One insulator were stuck though, so I had to unscrew the complete hook. Luckily the weight on the closest pole were not that heavy, meaning I could by hand lift the pole, and place a large stone under the empty top hook. This freed the deeply buried insulator, so I could unscrew it. In the foreground stands three saved Deltas, while two are already packed down in my backpack.
