WebbGreen Book “Overhead Lines”. Depending on voltage and terrain, towers are typically 200 - 500m apart from each other. Many OHL designs are fitted with one or several earth wires at the top of the tower. These earth wires have two functions, firstly to protect the conductors from a lightning strike which might cause an outage and secondly in the WebbThe span of the overhead conductor affects the computation of sag and tension in a transmission line. Some design engineers assume that the curve is parabolic for ease of analysis. The parabolic approximation is true only when the sag is minimal in comparison to the span length. It is common on distribution lines. WebbIn this video, I discuss and show the installation of the contact wire for overhead wire operation. Good soldering skills are a must for this.
