Distribution Pole
A common sight along roads, alleys, and rural landscapes, carrying the medium-voltage lines that bring electricity from substations into our neighborhoods: the microvasculature of the grid.
One pole, then a line
On its own a distribution pole is the simplest thing on the grid, which is exactly why the pole-top transformer matters: it is the icon that tells you the whole assembly is electrical, and shrinking it to LEGO scale was the puzzle I most wanted to solve. What really drew me was repeatability. One pole is a detail; a row of them is a distribution line, so I designed it to be built again and again. I also wanted it to vary the way real utilities do, swapping crossarms and hardware for different pole styles, so the design leaves room for interchangeable parts rather than fixing one configuration.
What I actually wanted to build were transmission towers, but I started here on purpose: something simple enough that I could not get it wrong. A single pole with its pole-top transformer was the obvious first goal, low-risk but unmistakably from my field. It became the on-ramp I needed into tower structures, and what I learned standing something tall and skinny up in bricks fed straight into the lattice and monopole builds that followed. The part that fought back was the transformer: getting something that iconic to read at LEGO scale took more fiddling than the rest of the pole combined. Having already built the padmount transformer, I liked that this extended the distribution side of the grid instead of repeating it. The idea I keep circling is making it modular, a base pole with interchangeable crossarms and hardware so one design could cover a whole family of pole styles, the way the real ones do. That is a kit I expect I will end up building properly.
The grid, mostly
If the wires business has an atomic unit, this is it: a pole, a crossarm, a handful of insulators, repeated until it reaches the edge of the grid. BEPCO's founding was largely a matter of planting them from town to town in straight lines, one after another, until the places at the end of the wire had light. The Company's records give each pole its own number, though no lineman has ever told two of them apart. Its Instruction Booklet is one of the shortest in the Archive, the design having changed little since the first pole went into the ground.
