All c.a.c. poles produced according to Enel Technical Specification DS3000 Rev.8, are manufactured by cage assembling longitudinal re-bars wrapped into a steel spiral. The number and diameter of the re-bars are designed with care to optimise the performance of each single product.
For concrete casting we only use raw materials of a high quality which is checked regularly. We do this so to ensure we obtain the best mixtures possible for the maximum range of security. The result is a mixture with resistance high enough to fall within CLASS RCK greater than or equal to 540 daN/sqcm.
We use a mechanical centrifuge for concrete compaction, which results in an extremely compact mixture and a final product that is waterproof, whilst protecting the internal steel reinforcement for maximum durability.
