Cabling conditions in Welkom

Welkom was built on the Free State goldfields, and mining still shapes cable demand here. Shafts, hostels and processing plants need trailing cable, armoured feeders and regular repairs, while closed mines leave abandoned infrastructure that attracts copper thieves. Matjhabeng Municipality supplies the town, and its ageing network has suffered from theft and outages, pushing homes and businesses towards solar and backup systems. The surrounding maize and sunflower farms rely on long underground feeds to centre-pivot irrigation and boreholes. Hot summers bring lightning on the open plain, so surge protection and proper earthing are common requirements.
