Transformer containment bund ERT® R

stainless steelconcretesteel

The range of ERT-R containers includes adaptations to enable the transformer and ERT container package to be rolled using the transformer’s own wheels. Our engineering department defines the structure for adapting the transformer wheels to the standard transformer containment unit for ranges from 160 to 3150 kVA, and customised units for higher power ratings or special configurations (IC, TSA, TCI, AT, etc.). The ERT-R option does not include wheels. Description of the standard ERT-R range: S235 steel tank, thickness 3, 4 or 5 mm; hot-dip galvanising certificate to ISO EN1461-2022. Double watertight welding on all parts of the retention tank area to ensure complete watertightness, with individual quality inspection before leaving the factory. The upper part of each tank is fitted with an EXTICOV CCF type extinguishing system consisting of CNPP-tested suffocating slats. A set of 2 support beams is fitted widthways above each ERT-R tray, making it easy to place the equipment on the trays. The support beams are adjustable: their ideal position corresponds to the ECODESIGN standard; they can however be moved forward or backwards by one notch in relation to this standard. They are fastened to oblong-hole plates using 4 HM10x30 bolts with stainless steel “nylstop” locknuts and wide washers (LL) (supplied). The maximum weight of the transformer on the ERT® R enclosure is calculated according to the NFC 51.51 standard centre-to-centre distance. At the foot of the bund, two watertight wall penetrations are available to accept 1.5″ ¼-turn valves: the first valve to allow the bund to be emptied, and the second to fit an SPI® PETRO PIT rainwaters filtration kit.
