Course Description

Overhead Lines form the majority of Transmission and Distribution Circuits due to their much lower cost than equivalent cables at the same voltage and current ratings. An Overhead Line is a set of 3 wires, onefor each phase, referred to as the conductors. At Transmission Voltage Levels the conductors are normally strung on steel-latticed towers of many different shapes and size. However at Distribution (lower voltages), constructions in timber and occasionally reinforced concrete are used. The seminar addresses the technology over a wide range of voltage levels for both transmission and distribution circuits.

Course Objective

 

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