To perform trial installation of insulated cross arms on the towers of an operational 132kV circuit and monitor them for a period of up to two years to evaluate their electrical and mechanical performance when used in a real live operational environment.
  • Install Insulated Cross Arms on an operational 132kV tower line.
  • Capture the learning of the installation methods.
  • Monitor and evaluate the installed trial  Insulated Cross Arms for both electrical and mechanical performance in order to establish their readiness for use in the real operational environment.
The successful installation of the cross arms along with capturing the learning from their installation.
