The tables below separate the 50\u2013630 kVA configurations from the 800\u201340,000 kVA configurations. They show reference voltage combinations, vector groups, no-load and load losses, no-load current and short-circuit impedance. Use the exact project model and approved manufacturer drawing to confirm the final values before procurement.<\/p>\n<h2>How to Read the 35 kV Transformer Tables<\/h2>\n<p>The smaller 50\u2013630 kVA group lists a 35 kV high-voltage winding with a \u00b15% tap range, a 0.4 kV low-voltage winding and a Yyn0 vector group. The larger models list different secondary voltage options and Yd11; some models also list a 38.5 kV high-voltage option. These are distinct configurations, not interchangeable settings on one unit. Confirm voltage, frequency, tap arrangement and vector group against the approved single-line diagram.<\/p>\n<p>The first table expresses loss figures in watts (W). The second table expresses its loss figures in kilowatts (kW): for example, 1.23 and 9.9 for the 800 kVA model. The former page labeled both tables in W, which made the larger-model values misleading. The numerical values below are preserved from the published schedule; request the signed technical data sheet for contractual or efficiency calculations.<\/p>\n<h2>What to Confirm Before Ordering<\/h2>\n<figure class=\"wp-block-table\">\n<table>\n<thead>\n<tr>\n<th scope=\"col\">Quy\u1ebft \u0111\u1ecbnh<\/th>\n<th scope=\"col\">Project information to provide<\/th>\n<th scope=\"col\">What the final data sheet should confirm<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Nhi\u1ec7m v\u1ee5 \u0111i\u1ec7n<\/td>\n<td>Rated capacity, maximum demand, primary and secondary voltage, phase, frequency<\/td>\n<td>Selected model, winding ratings and tap range<\/td>\n<\/tr>\n<tr>\n<td>Network connection<\/td>\n<td>Single-line diagram, neutral and earthing arrangement, upstream protection<\/td>\n<td>Vector group, terminal arrangement and impedance<\/td>\n<\/tr>\n<tr>\n<td>Losses and performance<\/td>\n<td>Required efficiency evaluation and operating load profile<\/td>\n<td>Guaranteed no-load and load loss units, reference temperature and test method<\/td>\n<\/tr>\n<tr>\n<td>Site conditions<\/td>\n<td>Indoor or outdoor location, ambient temperature, altitude and available space<\/td>\n<td>Cooling method, enclosure or tank arrangement, dimensions and mass<\/td>\n<\/tr>\n<tr>\n<td>Acceptance<\/td>\n<td>Applicable standards, required tests, certificates and delivery documents<\/td>\n<td>Approved drawings, routine test report and final nameplate<\/td>\n<\/tr>\n<\/tbody>\n<\/table><figcaption>Quotation checklist for a project-specific 35 kV oil-immersed transformer.
