Design of overhead powerlines with PLS-CADD

PLSCADD is constantly updating and enhancing the features of the software and engineers must keep abreast of the changes to ensure they gain the maximum benefit from the software. Like most software, ensuring the data integrity and input is vital to achieving valuable and worthwhile outputs. Universities are equipped with enough instruments and equipment to sharpen students with other practices than design software. This course will deal with turning theories into practice and will focus on the use of PLSCADD software for line design, tower spotting, tower and pole design.

DATE OF THE TRAINING: March 14, 2022, until March 18, 2022


ELIGIBILITY: Open for all nationalities

TRAINING PROVIDERS: EFLA consulting engineers in partnership with Nziza Training Academy

TRAINING LOCATION: Kigali city – Rwanda

ADDRESS: KN1 Avenue, Quartier de Kiyovu, Kigali ONOMO Hotel


Most of engineering sectors throughout the world are experiencing a shortage of competent engineers to execute complex projects. It is essential for engineers to continuously increase their knowledge on evolving engineering techniques and technologies. Power line designers must be familiar with commonly used design software to enable them to perform necessary evaluations to determine the suitability of a design to satisfy statutory requirements as well as optimize designs thereby reducing capital costs.

The training will be conducted by engineers from EFLA consulting engineers who are accredited trainers in PLSCADD and agents for PLSCADD in the Nordic countries. Our courses are both for beginners and advanced users of PLS-CADD software. The instructors are experienced in engineering and design and have decades of experience using and teaching PLS.


This course is intended for all line design engineers who currently use or are planning to use PLS-CADD software.

The attendees should have a basic understanding of power line design and the process and concepts involved. The course is focused on the use of PLS-CADD and no prior knowledge of PLS-CADD required. The course does not cover the fundamentals of line design; however, a separate course is available


The training will focus on use and understanding of the software. It is estimated that the course will cover one week, 8 hours per day. This is a hands-on course and delegates will be given examples to complete with support from the instructors.




Provide delegates an in-depth understanding on the PLS suite of software and line optimization using PLSCADD. The course will also teach delegates how to setup a project in PLSCADD, tower spotting to obtain an optimum line design and tower positioning. The course also covers engineering checks to ensure the line is compliant to statutory requirements and the creation of construction documentation to facilitate line construction activities. This course takes you on the complete steps in your learning journey, teaching you from the basic skills you need to start and finish any lines project in energy sector.

This course will teach how to use PLS-CADD on a transmission or distribution lines project from start to finish, including importing survey data, criteria development, structure design, conductor sagging and Plan, Profile drawing development and plotting.

Practice your new skills and test your knowledge with exercises and challenging assignments. The course has practical activities requiring hands-on participation by the attendees who will complete assignments during the course thereby cementing their knowledge of the software.

It is expected that each attendee will have their own PC with the latest version of PLS-CADD loaded.


The course lessons are project-oriented to enable delegates with the necessary tools and knowledge to setup, complete a PLSCADD project for tower spotting, and line optimization. Delegates will obtain practical experience in the use of PLSCADD suite of software.

PLS approved EFLA Consulting Engineers will deliver this course.

EFLA Consulting Engineers are comprised of Norwegian PLS approved instructors as they are found in our team of instructors assigned to this course.

Certificates of attendance will be provided in a week after the training closure via attendee’s email.


EFLA has the skills and competencies to deliver it at highest standard, and appropriate presentations will be created for the course.

Exercises and examples will be provided were possible to enforce the understanding of the software.
