The panelled electrical substations assembled on site supplied by Betoncablo S.p.a. are extremely flexible in size and meet all the architectural technical requirements of our customers. Backed by our consolidated engineering experience, we offer our customers the possibility to create substations of any size, both in plan and height.
The construction system consists of vertical panels and roof slabs constructed in varying sizes that are assembled on site using a system of dry mechanical joints with earthquake restraint. Moreover, the substation can be disassembled for subsequent reuse.
The substations are positioned on an underlying foundation tank, also prefabricated, which is first laid on a single reinforced concrete clean substrate. The foundation elements are supplied with PVC flanges with predetermined fracture toughness pre-installed during casting to house the pre-assembled cable gland system kit. The continuity between the internal and external earthing grid system is achieved using UNI EU-58 steel connectors which are also incorporated in the casting.
The panelled electrical substations assembled on site, normally supplied with a flat roof, may be constructed with a double pitched roof. The roof is made waterproof by means of a plastomer-polymer bitumen membrane, reinforced with a non-putrefying, isotropic, heat set continuous polyester fibre non-woven fabric which is applied when hot.
The panelled electrical substations assembled on site comply with Enel DG2092 requirements and unification tables; they may also be supplied complete with the necessary electromechanical equipment, fittings and wiring pre-installed.
