Industrial Plant Single Line Diagram Examples & Generator
Industrial plants rely on clear single line diagrams (SLDs) to design, operate, and maintain electrical power distribution systems. This collection showcases ready-to-use SLD examples for cement plants, pharmaceutical facilities, automotive assembly lines, and petrochemical refineries. Whether you’re an electrical engineer, plant manager, or maintenance planner, these templates give you a head start.
Describe it in plain English — the AI drafts it, you edit. No template wrangling.
About these examples.
A single line diagram simplifies a three-phase power system into a single-line representation, showing the interconnection of generators, transformers, switchgear, and major loads. With an accurate SLD, you can quickly assess load flow, fault levels, and protection coordination—critical for safety and reliability.
Use our free single-line diagram generator to create a custom SLD for your plant. Start from a prompt, upload a specification, or modify an existing diagram—all without CAD software.
Make one yourself.
Describe your plant's electrical system
Enter the main components—transformers, generators, switchgear, motors, and loads. Specify voltage levels and bus configurations.
Adjust layout and symbols
Drag and drop symbols or use AI suggestions to arrange feeders and buses. Customize with per‑voltage coloring and standardized icons.
Add labels and ratings
Include equipment ratings (kVA, kW, voltage), feeder sizes, and protection device settings.
Review and export
Preview the diagram, edit if needed, then export as SVG, PNG, or PDF for documentation and reports.
