PLS-CADD is the most powerful overhead power line design program on the market. PLS-CADD runs under Microsoft Windows and features an easy to use graphical user interface. It integrates all aspects of line design into a single stand-alone program with a simple, logical, consistent interface. No other program can match the sophisticated engineering capabilities available in PLS-CADD. This sophistication and integration leads to more cost-effective designs being produced in only a fraction of the time required by traditional methods.

PLS-CADD addresses the reality that terrain modeling, engineering, spotting, and drafting are not disjoint processes but are all interrelated. By integrating all these functions into a single environment PLS-CADD streamlines the design process. The result is simplicity, flexibility and efficiency not attainable when using a collection of programs from different vendors. PLS-CADD’s engineering features are unsurpassed giving you the state-of-the-art in sag-tension, structural analysis and automatic spotting. From distribution wood poles all the way to 500 kV or higher guyed frames and lattice towers, PLS-CADD has the power and flexibility to do it all. Proven in over 1000 organizations in more than 115 countries, PLS-CADD is the worldwide standard in line design.


  • A Microsoft Windows XP, Vista, 7 or 8 (32 bit or x64) environment that lets you:
    • Run on powerful yet inexpensive computers
    • Use the most common graphical user interface (GUI) in the world
    • Print reports and plot drawings directly on a wide variety of printers and plotters
    • Run the user interface in English, French or Spanish
  • A 3-dimensional terrain model (including automatic TIN triangulation) that lets you:
    • Select your route by clicking the mouse on line angle points
    • Move structures in the plan or profile views
    • Automatically generate centerline or side profiles
    • Identify any terrain or obstacle with a unique feature code and symbol
    • Automatically draw the required vertical clearance line for any specified voltage
    • Render terrain in color by elevation and light incidence
    • Import terrain data from GPS, photogrammetry or total station surveying equipment
  • A simple system for strength and clearance design criteria that lets you specify:
    • Weather cases with individual wind, ice, temperature, and reliability adjustments
    • Load factors for checking the strength of the structures
    • Cable conditions (Initial, after Creep or after Heavy load)
  • A 3-dimensional model of the line that lets you:
    • Represent all structures with all attached cables and insulators
    • Select structures and cables from user editable libraries

    • String and sag the line interactively or automatically
    • Perform any sag and tension calculation, including the effect of creep
    • Select various conductor models to better represent behavior at high temperature
    • Determine complete design loading trees
    • Compute vertical or lateral clearances from ground or obstacles to any cable
    • Check structure strength by allowable wind and weight spans methods
    • Check structure strength by direct link to structural analysis programs
    • Check clearances between conductors and structures (including guy wires)
    • Visualize the line in 3-d with actual wind blowout and insulator swings
  • A graphics system that lets you:
    • Generate plan & profile sheets automatically
    • Plot directly or send drawings to commercial CAD system
    • Export plan & profile sheets to PDF (requires Adobe Acrobat)
