High Voltage & Substation WorksSydneyFixed price, done first visit

High voltage and substation electrical work sits at the top of the commercial electrical scope — new kiosk substations for large developments, chamber substation refurbishments for strata and industrial sites, transformer replacements, and LV distribution downstream of the transformer. Empire Electrical Contractors delivers the LV scope end to end and coordinates with accredited HV partners for the switching, testing and commissioning that requires HV tickets.

Typical projects include a new commercial fit-out where the tenancy needs a dedicated transformer and metering; a strata scheme with an aging chamber substation that has been served an insurer or Ausgrid defect notice; and a light-industrial site upgrading from a padmount transformer to a kiosk arrangement to free up land. We handle the LV switchgear, cable ladders and trays, main switchboards, distribution boards, earthing and bonding, and the compliance documentation the network operator requires for energisation.

Every HV/substation project is delivered against a written program with defined hold points for HV switching, insulation testing, protection testing and network sign-off. $20M public liability and full workers cover — insurance certificates and induction paperwork provided for every site.
