Terminated Isolation Conductor


Isolated Downconductor is a specialized lightning protection downconductor, that during operation may be subjected to impulse currents of over 100kA and voltage of up to 700kV may be developed. The ISODC is designed and tested to control separation distance and arching. A semi-conductive outer layer is used to minimize voltage gradients under lightning conditions. The ISODC is available with a copper or aluminum core.


  • Provides protection of equipment against lightning strike flashover by providing an insulated path to ground via an equivalent safety distance
  • Supplied with factory upper termination and materials for field installed lower termination
