Rocla has supplied 414 spun concrete distribution poles to the Enel Green Power developed Karusa and Soetwater wind farm projects in the Northern Cape. These are for an overhead line required to join into the Eskom Komsburg Station.

“We worked closely with the customer to ensure that our poles met their strict customised requirements,” explains Kevin West, sales consultant for Rocla.

Pole lengths varied from 15.6 m to 19.2 m for the overhead line. Rocla supplied 146 distribution poles for the Karusa wind farm and 268 poles for the Soetwater wind farm.

Spun concrete distribution poles are a cost-efficient choice due to small servitude requirements and are quick to install, providing a durable, long-term solution with minimal maintenance. A key feature is that these poles are exceptionally strong through 360 degrees, not having the major and minor load axis that normal poles exhibit. Additionally, the unique centrifugal manufacturing process used gives Rocla spun concrete poles extra strength properties not found in cast concrete poles. Rocla’s spun concrete poles also offer a lifespan of over 50 years.

Rocla manufactures a range of concrete pole solutions for electrification, reticulation, telecom masts, lighting, security monitoring and stadium use.
