WebAn overhead power line’s capability to transfer power is related to the distance over which the power must be transmitted. Three main limitations depending on the power transfer distance are imposed on the overhead power lines. These are the thermal limits for lengths of less than 80 km, voltage drop limits for lengths of between 80 km and 320 km Webinsulators vs. 2-parts insulators such as V-strings, the most common cited benefit of the V-string is the control of conductor position and its effect on clearance to the supporting …
