Transformer containment bund TRT-W

galvanized steelrigid

Description of the TRT-W standard range: S235 steel tank, thickness 3 or 4 mm; hot-dip galvanising certificate to ISO EN1461-2022. Double sealed welds on all parts of the retention zones to guarantee a completely watertight tank, with individual quality inspection before leaving the factory. At the bottom of each TRT® W trough, a set of 2 support beams is installed in the width direction. These adjustable beams make it easy to place the electrical transformer in the trough and keep it above the ground level of any residual water that may be present at the bottom of the trough when used outdoors. You can adjust the position of the TRT® beams on site to suit the centre-to-centre distance of your transformers. At the foot of the bund, two watertight wall penetrations are provided by 316L steel/stainless steel inserts to accommodate 1.5″ diameter valves: the 1st valve to allow the bund to be emptied, and the 2nd to fit an SPI® PETRO PIT rainwater filtration kit. In the standard version, the bund is supplied with the two wall passages sealed with stainless steel plugs. A safety siphon is always fitted to TRT-W drip trays. Fitted at the top of the drip tray, it enables overflowing water to be drained off without draining oil in the event of heavy rain or blockage of the filtration system. Threaded outlet supplied with plug: don’t forget to remove the plug if using outdoors. Each TRT has 8 earthing points with lugs at each corner of the tray (lugs not supplied).
