Zwartkop Substation repairs to drag into the weekend
The City of Tshwane says Energy and Electricity technicians have been working tirelessly to operationalise the Zwartkop Substation, which caught fire on Tuesday morning.
The substation suffered major damage and left various areas in Centurion and Pretoria East without electricity.
On Wednesday, the Transformer B2, which the team had been testing rigorously, successfully passed all high-voltage tests.
However, the transformer’s cable end box still needs to be replaced as it was severely damaged during theft and vandalism.
Tshwane spokesperson Lindela Mashigo says a specially ordered cable end box for the backup transformer is expected to arrive on site by Friday, after which cable termination will commence.
"Once the new cable end box is installed and cable termination is completed, the transformer will be safe to operate.
"The team has now started excavating to replace the damaged feeder and control cables, technicians have commenced with cold commissioning of the substation with the tests on feeder panels.
"Simultaneously, the team is also working on oil purification for the transformer. The estimated time for restoration will be communicated once the bulk of the repair work has been completed."
