Ganged 10′ and 20′ sections provide expedited installation.Standard configurations are spaced to accommodate medium voltage heat calculations.Durable cradling allows for jobsite conditions.Place the assemblies in the trench in the correct sequence and connect the sections together.
The sections are rebar reinforced and very robust so they can easily be shipped anywhere in the world. The straight section and Transitional section assemblies are both built ready to install in 10’ or 20’ sections and can be used in both direct bury and concrete encased applications. Compared to a traditionally built duct bank, our straight Duct Bank assemblies are installed up to 60% faster and our engineered to order (ETO) transitional duct bank assemblies are installed up to 90% faster. When you use our NEC compliant Excellerate Duct Bank solution, your workers are exposed to the Trench DANGER ZONE for much LESS time. According to many safety institutions trenching is one of the most dangerous activities in construction.
