Project setup
In utility design, the "tower top" or "pole top" geometry dictates how insulators, crossarms, and conductors are attached to the structure. In PLS-CADD, these are managed via framing files or method 4 structure attachments. Downloading pre-configured tower tops saves engineers hundreds of hours of manual coordinate drafting. The Risks of "Free Downloads" from Third-Party Sites

Select if you need to route lines, calculate clearances, and manage total line alignments.
Altered binaries can introduce silent bugs into the calculation engines. A misplaced decimal in a sag-tension or wind loading calculation can lead to catastrophic structural failure in the field.
Let’s assume you want to:
: The Structural Analysis Program for Static systems. This is the finite element engine that handles the heavy-duty non-linear analysis for cables and structures within the other programs. Free Download Options Power Line Systems maintains an extensive, free online
A specialized module for the analysis and design of utility poles made of wood, steel, concrete, or fiber-reinforced polymer (FRP).
→ “Demo Software” → “PLS-CADD Demo Installer”.
PLS-CADD allows you to define attachment points (insulators) relative to the structure.
In PLS-TOWER, a “tower top” refers to the upper section above the waist. These are defined using .tow files. You cannot “download” generic tower tops because each project requires customized geometry, load cases, and connection details. However: Select if you need to route lines, calculate
The primary overhead line design and analysis software suite is provided by , now part of Bentley Systems. While full commercial versions of these professional tools are not available for free, a limited streamlined version is offered at no cost to the engineering community. PLS Software Overview
SAPS is the finite element analysis (FEA) engine driving the calculations behind PLS software. It handles non-linear structural behavior, which is critical when analyzing flexible structures and large conductor displacements under extreme wind or ice. The Role of Tower Top Geometries
Use the 3D graphics feature to verify clearances between conductors and structure members (including guy wires).
