Cabling conditions in Sandton

Sandton's office towers, hotels and data-heavy businesses make it one of the biggest users of commercial cable in the country, from large power feeders and busbar risers to structured network cabling. Many of the area's offices and homes are supplied directly by Eskom, and businesses invested heavily in generators, UPS systems and solar during load-shedding. Large homes in Bryanston, Hyde Park and Morningside often need upgraded supplies for pools, air-conditioning, smart-home systems and backup power. Sectional-title apartment buildings require compliant rising mains and sub-metering. Frequent Highveld lightning means surge protection is standard, and cable theft is a concern even in upmarket areas.
