About the Transformer black filled icon
A rectangular substation housing carries a lightning bolt on its face, topped by three columns of stacked insulator discs. The drawing points to power distribution, voltage step-down and grid infrastructure rather than a generic energy mark. It suits utility dashboards, electrical engineering diagrams, energy company sites, industrial safety notices and infrastructure map legends.
Trapezoid insulator plates repeat three times per column to signal high voltage, while the bolt sits centered and slightly angled for balance. Pair it with power line, meter and solar panel icons; keep it at 32 px or larger so the stacked discs do not merge together.
This is the solid black filled version of the transformer icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
