You do not ignore that oil is the good thermal conductor, so we find it inside power transformers to help its cooling process. You even know that, power transformers are part of transformation or electrical stations, located close to major cities or industrial zones, and that, different oils can be used in high power transformers equipped with oil conservators: mineral oils, silicon oils or vegetal ones<\/strong><\/span>, each one getting its own properties.<\/p>\n You already noted that on site, it is often necessary to store dielectric oil:<\/p>\n This lead us to an analysis between the two possibilities to store dielectric oil which can be selected by maintenance team: a rigid tank or a flexible one. But, which is the best solution? Let\u2019s consider a 40m3 storing capacity, to compare both solutions.<\/p>\n On one hand, we have the flexible tank solution, with a weight of 200 kg<\/strong><\/span> when empty, and without its accessories. On the other hand, a metallic tank which weights 3.000 kg<\/strong><\/span>!\u00a0 There is a huge gap of 2.800 kg<\/strong><\/span> between both dielectric oil storage systems. I don\u2019t know about your opinion, but for transportation and a quick installation on site, a light solution seems to be better. Talking about transportation, let\u2019s introduce the second point\u2026<\/p>\n Whatever, you have to transport and bring your solution on site, so packing dimensions have a big importance and must be considered on your selection. For the flexible tank, packing dimensions will be 1.60 x 1.22 x 0.7 m<\/strong> <\/span>versus 6.5 x 2 .5 m for the metallic one<\/strong><\/span>.\u00a0 Once folded, the flexible tank is much smaller than its competitor.<\/p>\n 2nd point for the flexible one!<\/p>\n <\/p>\n For its deployment, the flexible tank will require a little elbow grease and a team composed with muscled guys. Indeed yes, this solution only requires a manual installation<\/strong><\/span> (30 minutes installation with 2 people), there is no additional tool or crane needed contrary to the metallic tank. So, do you prefer an installation with crane? This is your choice\u2026<\/p>\n<\/div>\n [\/vc_column_text][\/vc_column][vc_column width=”1\/3″ offset=”vc_col-lg-6 vc_col-md-6 vc_col-xs-12″][vc_single_image image=”6212″ img_size=”large” alignment=”center”][\/vc_column][\/vc_row][vc_row content_placement=”middle”][vc_column width=”1\/2″][vc_single_image image=”3910″ img_size=”large” alignment=”center”][\/vc_column][vc_column width=”1\/2″][vc_column_text]<\/p>\n This point is for the metallic tank. The space needed to install it 8 m long over 2.5 m<\/strong><\/span> width whereas the flexible oil storage tank requires a special space of 6.7 x 6.7 m<\/strong><\/span> for its deployment. Nevertheless, once folded, it has a low occupation rate to be stored<\/strong><\/span>; that can be taken as a good compromise.<\/p>\n Regarding the non-contamination possibilities, this point goes to the flexible storage tank. Thanks to its flexible material, which follows the oil level during volume variations ans does not allow any air entrance, so air can never be in contact with oil<\/strong><\/span>. This process is more complicated for the rigid tank\u2026 seems like you wanted to exhaust air from a bottle.\u00a0 A flexible compensator <\/a>to be placed inside will be highly recommended to avoid any contact between oil and air, and so, hydrocarbons contamination. Don\u2019t forget that this kind of contamination could cause trouble to the transformer use<\/strong>.<\/span><\/p>\n Additionally to all advantages mentioned before, we should also note that a 40m3 flexible storage tank for dielectric oil and hydrocarbons costs around 6000\u20ac<\/strong> <\/span>(without its accessories) against approximately 8500\u20ac for a metallic tank of 40 m3<\/strong><\/span>. Choose carefull; an important project does not mean an expansive one, isn\u2019t it?[\/vc_column_text][\/vc_column][\/vc_row][vc_row css=”.vc_custom_1553615210143{margin-top: 15px !important;}”][vc_column][vc_separator][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]Throughout those 6 elements, we pointed out it is preferable and more convenient to select a flexible storage tank for your needs of power transformer dielectric oils storage. Nevertheless, don\u2019t forget to anticipate the available space on site to be able to install it.<\/p>\n\n
