Power Lines Upgrade

There's an area where they are upgrading the power lines there's the primary ones up high on the poles shown here (these are 115kv according to one of the guys on GOL).

Note the wheel-thingies used for feeding wire along the poles! Once the section of wire is complete those will be removed.
The insulators don't show real clearly, but you can atleast see just how far they come out from the pole.

You can also see a lower mounting arm for more wires...that's where the colored lines shown in the previous pic will go.

(and in the background is the original poles/lines that are being replaced)
