Web- Insulators that are connected to supports and insulate the conductors from the earth. - Cross arms which give support to the insulators. - Miscellaneous elements such as phase plates, danger plates, surge arrestors, etc. The overhead line operation continuity depends upon the judicious selection of above elements. WebStringing Efficiency: The Ratio of the voltage across the whole string to the product of numbers of discs and the voltage across the disc nearest to the conductor is known as string efficiency. String efficiency is important for the overhead transmission line.
