COURSE OVERVIEW:

Overhead transmission and distribution lines form the vital arteries of the electrical grid, exposed to the harshest environmental and mechanical stresses. This course provides a technical framework for the design, erection, and long-term upkeep of overhead assets, from wood-pole distribution to high-voltage steel towers. Participants will explore the mechanics of "Sag and Tension" and the structural engineering required to withstand wind, ice, and thermal loading.

The scope of this training addresses the full lifecycle of overhead lines, including right-of-way clearing, pole setting, conductor stringing, and the installation of hardware such as insulators and dampers. It covers the technical nuances of "Condition Monitoring," focusing on the detection of corrosion, wood rot, and insulator tracking. The curriculum provides a detailed focus on "Live-Line" and "De-Energized" maintenance techniques, ensuring that participants can manage the unique safety hazards associated with working at heights and near energized conductors.

Coverage includes the implementation of rigorous safety protocols, including "Working in Proximity" rules and the use of specialized aerial equipment. Attendees will learn to utilize diagnostic tools like infrared thermography and corona cameras to identify incipient failures in high-tension environments. By combining structural engineering principles with practical field-based maintenance, the course equips professionals with the expertise required to ensure the reliability and safety of overhead power infrastructure.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Define the structural and electrical components of an Overhead Line (OHL).
• Explain the principles of "Sag and Tension" and their impact on clearances.
• Identify different conductor types (ACSR, AAAC) and their applications.
• Supervise the "Pole Setting" and "Tower Erection" construction phases.
• Select and inspect "Insulators" (Glass, Porcelain, Polymer) for specific zones.
• Execute "Conductor Stringing" and "Splicing" with technical precision.
• Perform "Grounding and Bonding" for OHL structures and stay-wires.
• Utilize "Infrared Thermography" to detect high-resistance splices.
• Conduct "Visual Inspections" for wood rot, corrosion, and hardware wear.
• Implement "Safe Working Clearances" and "Fall Protection" protocols.
• Manage "Vegetation Control" and right-of-way maintenance cycles.
• Execute "Emergency Repairs" following storm or structural damage.

TARGET AUDIENCE:

This course is intended for Linemen, OHL Engineers, Construction Supervisors, and Utility Maintenance Personnel.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximize the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
