This unit involves the skills and knowledge required to install and maintain de-energised high voltage (HV) underground paper insulated cables in the electricity supply industry (ESI).

It includes completing and updating system data/maintenance records of de-energised HV underground paper insulated cables, jointing, terminating, repairing and replacing cables. It also includes isolating cables, issuing permits and undertaking pre-commissioning tests.

De-energised means separated from all sources of supply but not necessarily isolated, earthed, discharged or out of commission.

The application of the skills and knowledge described in this unit may require a licence/registration to practice in the workplace.

Other conditions may apply under state and territory legislative and regulatory licensing requirements which must be confirmed prior to commencing this unit.
