Substations are the backbone of a reliable power supply. Adoforce Electrical Contractors designs, builds, upgrades and maintains substations for low, medium and high voltage systems up to 132kV, helping utilities and municipalities reduce outages and support growing demand.
In 2025, Adoforce installed and connected new 20MVA power transformers at three Centlec substations to reduce outages and support growth in the Mangaung Metro:
A 20/22MVA, 132/11kV transformer reinforcing supply to fast-growing residential and business areas in northern Bloemfontein.
A 20MVA, 33/11kV transformer replacing a failed unit and restoring N-1 contingency.
a 20MVA, 33/11kV transformer creating N-1 contingency for the area.
Substation work leaves no room for error.
