Transformers & Switchgear
in Johannesburg.
ETS manufactures IEC 60076-compliant power transformers, distribution transformers, switchgear and package substations to utilities, EPC contractors, oil & gas operators, renewable developers and data-centre projects across Johannesburg. Triple-certified manufacturing (IEC, ANSI/IEEE, UL) supports utility-grade procurement with witnessed FAT, ISO/IEC 17025 testing and turnkey delivery.
Market context
Local grid, utilities, climate and procurement.
Johannesburg sits at 1,753 m elevation on the Witwatersrand and is supplied by City Power (the municipal utility) plus Eskom for transmission and a portion of bulk distribution. The grid runs 11/22 kV at MV and 88/132/275/400 kV at transmission, with the Apollo-Hydra HVDC link (1,920 MW) bringing Cahora Bassa hydropower from Mozambique. South Africa's chronic load-shedding (Stage 6 = 6,000 MW deficit) drives unprecedented demand for behind-the-meter generation, captive solar GSU transformers, mobile substations and emergency diesel-genset MV switchgear. Specifications follow NRS 002/004 (NRS = National Rationalised Specifications, derived from IEC 60076) with high-altitude derating ≥1,500 m and lightning-impulse-tested bushings (frequent thunderstorms in summer). Procurement is shaped by Eskom's 14 GW Just Energy Transition pipeline, the Special Risk Insurance reforms enabling private wheeling, and the Sasol Secunda gas-to-liquids complex. Tender hints: NERSA licensing and SABS-marked equipment are mandatory; ETS manufactures through Durban-port logistics.

Frequently Asked Questions — Johannesburg
Lead times for transformers and switchgear delivered to Johannesburg depend on the specification, scope of supply, order volume and prevailing factory load — distribution transformers (11–33 kV, up to 5 MVA) typically build and test faster than power transformers (33 kV and above, up to 60 MVA), and every quoted programme includes witnessed Factory Acceptance Testing and agreed delivery terms. Please contact ETS with your technical schedule for a project-specific delivery plan.
