Transformer

I wanted a picture of a frozen cobweb as I saw one on the way to work. I thought I would have plenty around my works as it was -3.5 when I got here. Unfortunately there was none about! so whilst checking some meter readings I thought I would get a quick snap of this transofrmer! I wouldn't like to touch it too much as there is a lot of power going through it. Reminds me of some old American electric chair mechanism
