Six bundle stringing of overhead conductors

A complete wrap-up of transmission line tension stringing for both newbies, managers and experts.

Overhead conductor tension stringing on all kinds of transmission lines at all voltage levels.

Some details:

  • Theoretical background of tension stringing.
  • Conductors, fiber optic cables, correct handling, etc.
  • Equipment and machines: Calculation of appropriate machinery and equipment.
  • Project and site organization.
  • Working methods in detail.
  • H&S, SJA, etc.

Manual calculation of induction voltages and currents:
A professional project management approach of working in proximity of energized circuits and plants and a solid basis for Method Statements, SJA and H&S plans.

The participants will be able to make their own independent calculations and assessments rather than blindly trusting “one-click results” from software programs.

  • Theoretical basics.
  • Geometric Mean Radius GMR of a multi-layer conductor and its calculation, GMD
  • Complex earth depth, etc.
  • Electric field induction, image conductors, capacitance of transmission lines.
  • Magnetic field induction, Carson’s self- and mutual impedance.
  • Effect of shield wires.
  • Calculation examples: Precise calculation according to the IEEETM 524 standard, Schnell / Clarke.
    “IEEE Guide for the installation of overhead Transmission Line Conductors”,
    IEEE Std 524-2016 (Revision of IEEE Std 524-2003, April 2017)
  • Comparison of the results with and without shield wires or underground cables with neutral.
    Alternative calculations according to Clem, Dubanton, etc. and their limitations.
  • Case studies: Non parallel circuits, pipelines, underground and telecommunication cables.
