Cabling conditions in Newcastle

Newcastle grew around steel and coal. A large steelworks, coke and chemical plants, and many textile and clothing factories use heavy three-phase supplies, armoured feeders and plenty of maintenance cable. Coal mining in the surrounding area and the nearby Majuba power station add industrial demand. Highveld-style summer thunderstorms bring frequent lightning, while winters are cold and frosty. Newcastle Local Municipality supplies the town, and cable theft and vandalism of municipal infrastructure are ongoing concerns. Residential work in Madadeni, Osizweni and the older suburbs focuses on rewiring, prepaid meter connections and backup power installations.
