Overhead Lines, Maintenance and Construction Course

Coure Course:

This course will teach you Overhead Line Technology with an emphasis on its design principles, maintenance, and requirements. Participants will gain skills in comparing underground cables and overhead lines, designing suitable support structures, and assessing routing of the cables including environmental impact.

This course is mainly application-oriented and includes line clearances and loadings, fittings, and impedance determination. Participants will also learn about modern technologies in foundation and soil investigation, conductor types and lightning protection.

Real life case studies and practice ensure active learning and makes the course appropriate for experience in project management especially operations, maintenance, assets and contractor management professionals.

Its industry-focused approach makes it ideal as it helps staff to develop their skill sets to enhance effectiveness and reliability of electrical systems.

Course Objectives:

Upon the successful completion of this course, participants will be able to:-

• To ensure delegates develop their existing knowledge and are acquainted with the latest developments in Overhead Line Technology.
• In addition that the principles can be appropriately applied in everyday work to improve their personal effectiveness and efficiency.
