OVERHEAD TRANSMISSION AND DISTRIBUTION LINES DESIGN USING PLS-CADD, TOWER, POLE & FOUNDATION DESIGN

A steady increase in population and their continuous reliability in advanced technology has an uphill demand of power with respect to time. The end users are demanding more power, so it is necessary to increase the transmission capacity of existing power links as well as build new high voltage power links. As a design specialist in this field and involved in numerous projects every year, ETCBL Global offers training course on Designing Overhead Lines (OHL). Our training course provides a high level of insight and knowledge to overhead line design, covering all aspects of the latest technologies involved – electrical, mechanical, structural and civil using state of the art transmission line design software PLS Suite which includes PLS CADD, PLS Tower, PLS Pole etc.

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

IN HOUSE AND ONLINE TRAINING

While both In-House and Online training can present with cost-effectiveness and time-efficacy, there are some very specific differences between in-house courses and those based online.
The demand for additional courses by individuals or groups of people is increasing. Still, it depends entirely on the preferences of a person what type of training he or she wants to receive. Online courses and in-house training carry some similarities but they are considered to exhibit some very pivotal differences too. Despite that, both types of learning can be really beneficial for attendees.
