Transmission line engineering · 115–500 kV

From route selection to optimized line design.

Overhead transmission line engineering, 115 kV to 500 kV: route selection, structure and conductor design, clearances, and drilled shaft foundations — modeled in PLS-CADD and PLS-POLE, delivered as plan-and-profile an EPC can build.

Line design, end to end

01 / SCOPE
TX-01 · ROUTE

Route selection

Corridor and route studies — structures sited to terrain, constraints, and clearances.

TX-02 · STRUCTURES

Structure design

Pole and tower structures analyzed in PLS-POLE — load cases, capacities, and framing.

TX-03 · CONDUCTOR

Conductor & sag-tension

Where you set the conductor, I design to it; given an ampacity, I propose type and size — with sag-tension charts and manufacturer load tables.

TX-04 · CLEARANCES

Clearances

Ground, crossing, and code clearances verified through the modeled line.

TX-05 · FOUNDATIONS

Drilled shaft design

Drilled shaft foundations designed to the structure reactions (FAD Tools).

TX-06 · SET

Plan & profile

The PLS-CADD model and plan-and-profile drawings (AutoCAD) — construction-ready.

Modeled in the tools utilities and EPCs trust

02 / TOOLCHAIN
PLS-CADD

Line modeling, clearances, plan-and-profile.

PLS-POLE

Structure analysis and design.

FAD Tools

Drilled shaft foundation design.

AutoCAD

Construction drawings.

Line design — structures, conductor, clearances, foundations. System and protection studies sit with their specialists.

Three steps

03 / PROCESS
01ROUTE

Route & constraints

Corridor selection and structure siting to terrain and clearances.

02MODEL

The line is modeled

Structures, conductor, and clearances in PLS-CADD + PLS-POLE; foundations to the reactions.

03DELIVER

The set

Plan-and-profile, structure and foundation design, sag-tension and load tables.
