Cabling conditions in Gauteng

Gauteng is the country's busiest market for electrical cable, from surfix for home renovations to armoured cable for factories, data halls and new townhouse developments. The Highveld sees some of the highest lightning activity in South Africa, so earthing, surge protection and correctly bonded cable runs matter on every job. Supply is split between municipal utilities such as City Power, Tshwane and Ekurhuleni and areas fed directly by Eskom, which affects connection applications and meter positions. Years of load-shedding pushed many homes and businesses towards solar and battery backup, and cable theft remains a serious problem, so buried and exposed runs are planned with security in mind.
