spun concrete poles are centrifugally cast. This process involves spinning the poles at a very high rpm, which produces poles with the highest density and strength to weight ratio of any …
a testament to the value of spun concrete. But the power of spun concrete poles isn't just in their ability to resist extreme elements. Lower prices, simple installation, virtually no maintenance concerns and line sizes up to 345 kV (single or double circuit) make spun concrete a nearly perfect pole material. Backed by decades of
The NESC has determined the strength factor for concrete as 1.0 compared to 0.65 and 0.85 for wood in Grade B and Grade C construction, respectively. This strength factor is especially important when converting wood poles to spun concrete poles so that the wood pole is replaced with a concrete pole that is designed to the appropriate strength.
