Electricity Pole

A pole that can be connected to other poles to transfer energy

As of release 1.0.27X4109, there are now 3 variations of this, the normal one, substations, and the large pylons.

Substations are used to connect cables to the large ones, or can be used as a pylon as it's own with a 20m connection range, you can connect energy to this

Large pylons do NOT have a place to connect energy to, you need a substation for that. (Connection range of 100m)

Usage
Right-click on both poles with a Cable Drum to link them, poles can't be more than 25 blocks apart from each other, and a single pole may be linked to more than one. Cable drums are not consumed, so you only need to craft one. (same with the other variations with different range) (pretty sure 1 meter = 1 block)

Bug
There is a bug where poles in unloaded chunks, the red copper wires will partially disconnect from the tops. This is not just a visual glitch, these poles are actually disconnected, fortunately, this lets you know which ones need to be reconnected.

Trivia

 * In the game files, there are textures for Cable Drums of all the other types of wires (e.g. aluminum, normal copper, gold). Presumably, these wires would provide different power transfer rates or have benefits and disadvantages with each.
 * Either this idea was postponed for more important additions or dropped entirely.
