Underground Cable Installation for Cape Town homes and businesses

Independent electrical contractors working across Western Cape can walk the route, advise on trenching for local soil conditions, lay armoured cable at the correct depth, backfill the trench and certify the new circuit.

Cabling conditions in Cape Town

Salt air is the main enemy of cable in Cape Town. Along the Atlantic Seaboard and False Bay, exposed glands, lugs and outdoor DB boards corrode quickly, so stainless or brass fittings and sealed enclosures are worth the extra cost. Most suburbs buy power from the City rather than Eskom, and rooftop solar has spread fast, with the City requiring registration and approval before a grid-tied system is connected. Old Victorian and Bo-Kaap homes often still carry rubber-insulated or red-and-black wiring that needs replacing. Wet winters flood poorly sealed conduit runs, and cable theft remains a persistent problem along rail lines and streetlight circuits.

Typical underground cable installation requests in the area come from:

Homeowners: homes run armoured cable under the garden to a granny flat, pool pump or gate motor
Solar and backup power: ground-mounted PV arrays and remote inverter rooms are linked back with buried cable
Coastal properties: coastal sites use well-sealed glands and sleeves where groundwater and sandy soil are an issue
Complexes and body corporates: complexes trench new feeds to guardhouses, clubhouses and perimeter lighting around the estate
Offices: office parks bury cable between buildings, parking lighting and access-control booms
Municipal and public works: streetlight, park and sports-field feeds are buried and recorded for future maintenance
