Santo Antônio Hydroelectric

Santo Antônio Hydroelectric

Santo Antônio Dam is a hydroelectric dam set up on the Mareira River, in the state of Rondônia, Brazil. The dam is powered by 50 turbines for a total capacity of 3,580 MW.

For this major dam project, Dextra Do Brasil delivered to contractors Odebrecht & Andrade Gutierrezits its Rolltec rebar coupler solution.

Rolltec is the most popular rebar slicing solution in Brazil, providing a competitive alternative to lap splices. The rebar preparation is supported by a unique light equipment, operated by a single operator. The Rolltec machine is relatively easy to transport and convenient to install even on most remote locations such as dam construction sites.

On the Santo Antonio dam, rebar coupler were used to reconnect bent rebar. To do so, a straight bar is previously threaded (A/B/C thread length). The bar is then bent according to project requirements.

If needed, to protect the thread coupler can be temporarily set up onto the rebar as well.

Please consult us for more technical information about coupler applications on bent bars.
