Storage tank DEPOSITO®-MV

effluent recoveryfor power transformerstank

The DEPOSIT®-MV range comprises several references of prefabricated remote pits for your immersed transformers, which above 40 MVA must be equipped with a recovery tank connected to a separate storage tank. The pits in the DEPOSIT range from SANERGRID® can replace traditional concrete pits, which are very difficult to design and maintain over time. Description Above 40 MVA, the immersed electrical transformer must be equipped with a recovery tank with a capacity of at least 20% of the quantity of dielectric contained in the transformer, usually fitted with an EXTICOV™ or LHD® type extinguishing cover to guarantee rapid and natural extinguishing of the liquid dielectric if the oils remain trapped in it. This recovery tank must be connected to a separate storage tank, commonly known as a “remote tank”, with a capacity at least equal to that of the transformer with the highest capacity, when it is shared by several transformers. Description of the DEPOSIT-MV standard range: Double-walled in reinforced fibreglass: robust, reliable, and corrosion-resistant. Pressure gauge to detect any leaks or loss of watertightness. If one of the walls ruptures, the pressure drop between the two thicknesses allows the problem to be identified from the surface. Connections to the network are made using either nozzles (concrete, steel-cement), flanges or sleeves. Other types of connection can be studied according to your needs. The size of these connections and their diameter can be adapted on request to enable you to handle any flow of water. Standard pits are available in single volumes from 10 to 80 m3.
