Municipal electricity distribution and metering

Planting one of the prestressed concrete poles, supplied by Infraset. Johannesburg City Power specified prestressed concrete poles to replace timber poles in the electricity distribution network at Rabie Ridge, a suburb of Midrand which includes a mix of informal, low-cost and affordable housing.

The project also involved the installation of a split prepaid meterage system for over 1 900 houses – with new metering boxes and ready boards with keypads – as well as the installation of new street lighting, transformers and bundling conductors.

Infraset’s Poles and Masts Division supplied over 350 prestressed concrete poles for the project, mostly 10m tall, 8kN units and lesser quantities of 7.5m tall, 20kN units and 7.2m tall, 10kN units. Installation began in April last year, for completion by the year end.

The poles were supplied in a combination of earthed and non-earthed units and the 10m poles are supported by stays. Meterage boxes are placed at the top of poles with one box housing four meters.

The main contractor responsible for all the installation work on behalf of Johannesburg City Power was Kusokhanya Electrical Construction and all excavation work was handled by local subcontractors.

Kusokhanya’s project coordinator, James Rossouw, says that concrete poles were chosen for the upgrade because of their longer life spans, low maintenance needs, and because the I-section Infraset poles make it easy to mount the meter boxes at the top of the poles securely.

Product manager of Infraset’s Poles and Masts Division, Njabulo Khumalo, says the poles were cast in high-strength, high-density concrete with a smooth finish.
