The mini-subs will be utilised by the city of Johannesburg metropolitan municipality on various new projects and on the upgrading of existing infrastructure. The mini-subs are to be manufactured at the Actom Knights site in batches as required. They are of the 11 kV B type with power ratings up 1,000 kVA.
In addition, these units incorporate the latest requirements of City Power with regard to a low voltage connection point for a standby generator and data acquisition to a central control point. “They conform to City Power’s specifications and are manufactured to the latest international IEC and NRS standards,” Alec Duff, Actom MV Switchgear’s marketing manager says.
