The Sandpark substation which is the main source of power supply to Sandton was vandalised.
Eskom said in a statement on Tuesday that they had a serious incident of infrastructure vandalism at Sandpark substation.
TELECOMMUNICATION EQUIPMENT AND CABLES WERE DAMAGED
The substation protection, communication equipment, as well as cables were vandalised and created a major risk to the security of supply.
“The vandalism of this substation compromised the integrity and reliability of distribution of electricity, however, our technicians worked tirelessly throughout the night to ensure continuity of supply to Sandton. “
Eskom furthermore said temporal control measures were implemented to keep the substation operating while repairs to the substation continues.
Eskom has urged members of the public are requested to report criminal activities by reporting illegal connections, theft, and vandalism of electricity infrastructure to the Eskom crime line on 0800 112 722 or SMS 32211.
Meanwhile, the power utility has said that it is implementing load reduction from 17:00 – 22:00 to avoid network overloading in high-density areas on Tuesday afternoon.
The affected areas include Soweto, Bram Fischerville, Dobsonville, Dobsonville Gardens, Doornkop, Dube, Emdeni, Jabulani, Mmesi Park, Mofolo North, Moletsane, Naledi, Tladi, Zola and Zondi, and Glen Austin in Midrand.
During the load reduction implementation, customers are urged to switch off all their electrical appliances to avoid possible damage due to power surges when supply returns. Failure to do so may lead to transformer trips or failures, and damages to household appliances when supply is restored.
Eskom concluded by asking people not to report this outage.
