Transformer containment bund TRT LHD MODULO

metalconcretegalvanized

The TRT®-LHD®-MODULO range consists of multiple custom-made fire-protection containment units that interconnect in a modular system. SANERGRID®’s TRT®-LHD®-MODULO solutions ensure compliance with all regulatory and technical requirements for oil containment, fire protection, and hydrocarbon pollution control for large high-voltage power transformers, without incurring increased transportation costs. Modular fire-protection bunds for large power transformers Thanks to an innovative and robust assembly system, the TRT®-LHD®-MODULO range consists of 2, 3, 4, 5, or “N” interconnected modules. Each module includes a TRT®-MODULO bund equipped with a fire-resistant grating cover EXTICOV®-LHD®, connected to the others via the SNG-Flow™ communicating vessel system, allowing fluid passage between bunds. The TRT®-LHD®-MODULO range is recommended for large transformers when the bund’s width exceeds the European transport limit (2500 mm). This modular system allows the creation of extra-large bunds to accommodate high-voltage power transformers weighing over 300 tonnes and containing more than 100 tonnes of dielectric oil. A solution for challenging civil engineering constraints The TRT®-LHD®-MODULO system is also ideal for installations where on-site civil engineering is complex, outdated, or where excavating a concrete bund is not possible. Instead of a traditional concrete pit, the TRT®-LHD®-MODULO provides an above-ground bund installed on a reinforced, flat, and smooth concrete slab. This reduces civil engineering costs and significantly shortens the compliance timeline for electrical substations.
