Cabling conditions in Midrand

Midrand sits between Johannesburg and Pretoria and has some of the most active construction in Gauteng, with large mixed-use precincts, townhouse complexes and logistics parks along the N1. Developers and electrical contractors order cable by the drum for reticulation, sub-mains and unit wiring. Several large data centres operate in the area, adding demand for high-capacity power cable, cable tray and network cabling. Parts of Midrand are supplied by Eskom and others by City Power. Smallholdings around Kyalami and Blue Hills need long underground feeds to stables and cottages, and many residents installed solar and batteries during load-shedding. Lightning protection is important on exposed hilltops.
