This architectural drawing is the 2D design of a single-line electrical diagram in detail AutoCAD, CAD, and dwg files. Instead of depicting each of the three phases with distinct lines, a single conductor is represented with a single line in a single-line diagram. A single-line diagram simplifies the understanding of an electrical system, especially in the case of complex systems at substations. For more details and information download the drawing file.
