Distribution Overhead Lines
This course will enable delegates to become more conversant with operating, maintaining and refurbishing overhead lines and includes ‘hands-on’ practical exercises and site demonstrations.
It will allow you to develop your understanding of current standards and regulations for overhead lines with an emphasis on safety and best practice.
The course covers many of the relevant topics relating to overhead lines, including inspection and maintenance, conductors, insulators, lightning protection and the effects of environmental issues.
The course includes an update on recent and future developments in overhead line design and construction.
