WebFeb 24, 2012 · Sag is mandatory in transmission line conductor suspension. The conductors are attached between two supports with the perfect value of sag. This is because it protects the conductor from excessive tension. In order to permit a safe level of tension in the … Single stranded conductors are used in transmission system usually up to 220 KV… Cross arms of transmission tower hold the transmission conductor. The dimensio… There are three main types of Overhead Transmission Lines: Short transmission li… A rectifier is a device that converts alternating current (AC) to direct current (DC). I… Programmable Logic Controllers continuously monitors the input values from vari… WebNov 18, 2016 · 4. SOME IMPORTANT POINTS When same leveled two supports hold the conductor, bend shape arises in the conductor. Sag is very small with respect to the span of the conductor. Sag span curve is like parabolic. The tension in each point of the conductor acts always tangentially. Again the horizontal component of the tension of conductor is …
