CONCO substations:
custom-designed, constructed and installed

CONCO is recognised as Africa’s largest high voltage substation construction provider, with a capacity to construct substations from 11kV to 765kV. Our specialised engineers design, procure, construct and commission the following types of substations:

  • Conventional outdoor substations (AIS)
  • Gas-insulated substations (GIS)
  • Containerised mobile substations
  • Indoor cellular substations
  • 22kV-132kV Mobile substation skids for open-cast mining.

Turn the key; unlock the solution

Despite the necessarily complex design of our substations, CONCO produces flawless turnkey solutions; the mechanisms of engineering perfection for which our business is renowned. This is made possible as a result of strong project management, our own installation crews, our own design and testing systems and a large team of expert site managers.

Unbroken currents of productivity

Over the years, from green-field to brown-field sites, there is not a substation context CONCO has not encountered. More specifically, a function unique to our business is the upgrading of existing sites while keeping them energised. CONCO is also able to fit substations into very small footprints, based on the space that is available – and in line with IEC and SANS standards. Our design engineers are assisted in providing such solutions by our in-depth proficiency when it comes to utilising the latest technologies, including hybrid (compact) switchgear technology.

​Endless in-house staying power

Many substation contractors have to outsource specific elements of the process, but CONCO maintains full control of all projects, from inception to completion, by means of the solid, comprehensive in-house solution that is fundamental to our business philosophy. This approach is strengthened by an impeccable track record of expertly designed, constructed and installed substation projects, delivered on time, within budget, and as part of strict safety, health, quality and environmental policies.
