About the Transformer Lightning Bolt black filled icon
A rounded rectangular housing carries three tiered insulator bushings on top, each built from stacked trapezoid discs, and a lightning bolt inside a circle marks the live equipment on its front face. It reads as substation gear and voltage conversion, fitting utility company sites, power grid diagrams, electrical engineering slides, SCADA dashboards and hazard or maintenance signage.
The three bushings repeat at even spacing to give the mark a stable, symmetrical top edge, while the bolt roundel centers the large empty body. It sits well with power line, plug and battery icons. At small sizes the disc stacks blur, so keep it at 32 px or above.
This is the solid black filled version of the transformer lightning bolt icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
