A better spin on concrete power line poles?

Home Infrastructure Construction & Civils A better spin on concrete power line poles?

TRANSMISSION and distribution powerlines in suburban and rural areas need poles that can withstand harsh environments, inclement weather and vandalism, in order to ensure the continuous supply of electricity.

That’s according to Rocla, which says its spun concrete transmission and distribution poles are well suited for the exacting requirements of electrical distribution line construction.

“The durable, maintenance free spun concrete poles are exceptionally strong through 360 degrees, whereas normal cast concrete poles have a major and minor load axis,” the company said in a statement.

“The unique centrifugal manufacturing process gives a uniform densely compacted concrete along the whole length of the pole. This gives the Rocla spun concrete pole extra strength properties, not found in cast concrete poles.”

The company added that spun concrete transmission and distribution poles offer a cost-effective solution due to small servitude requirements, simple and economic funding methods and a quicker installation turnaround time. “They offer a durable, long-term solution with minimal maintenance.”

The company’s spun concrete poles systems are Eskom approved and have been tested at power utility’s Rosherville Testing Station.

“A bonus for the farming community as a result of the systems small servitude requirements is that is well suited to intensive farming on high-value land.”

Rocla offers a variety of pole lengths in single, jointed and double pole solutions, and its engineering technical team are able to customise solutions to meet specific customer sizing requirements as well as design and manufacture products for non-standard applications.

Spun concrete poles 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. The company is part of the IS Group which also includes Technicrete.
