Set the allowable stress for conductors and structural components.
Contains the engineering DNA of your project, including weather cases, wind/ice loads, automatic clipping constraints, and clearance requirements.
: Documents like the PLS-CADD Step-by-Step Manual on Scribd cover criteria setup, terrain data import, and conductor stringing.
It automates code checking for global standards like NESC, ASCE, IEC, and CSA. Software Architecture PLS-CADD operates in two primary modes:
The software creates a Triangulated Irregular Network (TIN) to provide a continuous surface for clearance checks. 3. Setting Engineering Criteria pls-cadd tutorial pdf
Evaluates the line for wind-induced, low-frequency oscillations (Single-Trimming or Double-Trimming methods).
Wind, ice, and temperature combinations (e.g., NESC Heavy, Extreme Wind).
Power Line Systems - Computer Aided Design and Drafting (PLS-CADD) is the global industry standard for overhead power line design. This comprehensive guide serves as a foundational tutorial for engineers, designers, and students looking to master the software. It covers everything from initial data import to final construction document generation. 1. Introduction to PLS-CADD
Ensuring lines meet safety codes (NESC, etc.). Set the allowable stress for conductors and structural
Used for quick, single-span calculations without a full terrain model.
Download sample projects from the Power Line Systems website to practice, as looking at static screenshots is not enough to gain proficiency.
PLS-CADD functions by building a three-dimensional model of the terrain and the transmission line. Unlike traditional 2D drafting tools, any change made in PLS-CADD—such as moving a structure or changing a conductor—instantly updates the engineering calculations, clearances, and material takeoffs. Key Capabilities
Select conductors (ACSR, AAAC, etc.) from built-in databases. The software calculates weight, diameter, and thermal expansion properties. 5. Sag-Tension and Stringing This is the "heart" of the software. It automates code checking for global standards like
Wind blowing on the structures and wires, plus the transverse component of wire tension at turning angles.
PLS-CADD is a powerful software used for designing and analyzing overhead power transmission lines. This tutorial has provided a comprehensive guide to using PLS-CADD, covering the basics of the software, creating a new project, designing the transmission line, analyzing load cases, and visualizing results. By following this tutorial, users can master the software and ensure the safe and efficient design of transmission lines.
Various lecture notes and lab descriptions from academic sources 1.2.2. 4. Tips for Maximizing Your PLS-CADD Learning
Used for wood, steel, concrete, or fiber-reinforced polymer single-pole structures.
