href=\"\/ja\/product\/oil-immersed-transformer\/\">\u6cb9\u6d78\u5909\u5727\u5668<\/a> page, with dry-type unit details on the companion dry-type pages \u2014 and the jump from 500 to 1,000 kVA nearly doubles the weight, which is why the crane and foundation planning changes between those two ratings.<\/p>\n<h2>How to Find the Exact Weight of Your Transformer<\/h2>\n<p>You do not receive the total weight from the nameplate as only the electrical specifications are available. Here are some of the reliable ways of obtaining it:<\/p>\n<ul>\n<li>Manufacturer\u2019s data sheet \/ technical specification \u2013 the best source for finding the requested information. Request it before you make an order.<\/li>\n<li>Packing list and bill of lading \u2013 if the transformer has already been sent to your location, the documents above provide shipping weight.<\/li>\n<li>Lifting label and rigging drawings \u2013 crates have both lifting weight and rigging points while the unit possesses it&#8217;s own lifting lugs rated according to weight.<\/li>\n<li>Catalog\/reference tables \u2013 handy for planning within the above mentioned tolerances.<\/li>\n<\/ul>\n<p>Should you decide to buy via a distributor, do not forget about the importance of the data sheet request (the weight is significant for freight quotes, foundation design etc.), or else a dealer who cannot provide the information must be considered as suspicious. Our <a href=\"\/ja\/product\/distribution-transformer\/\">\u914d\u96fb\u5909\u5727\u5668\u88fd\u54c1\u30da\u30fc\u30b8<\/a> publish the specification sheets for the units we supply; for a weight confirmation on a specific 500 kVA unit, the manufacturer&#8217;s data sheet is the authoritative source.<\/p>\n<h2>Weight in Practice: Transport and Installation<\/h2>\n<p>The mass you have verified now leads to three efficient choices:<\/p>\n<ul>\n<li>Shipping: a two-ton item must be transported as a crate on a flat bed or in a container; be sure to verify the height and weight restrictions along the way and the accessibility of cranes at both terminals. The shipping weight is approximately equal to 1.1 times the weight of the transformer.<\/li>\n<li>Lifting: it is important to employ the rigging points in accordance with the manufacturer \u2014 only lifting lugs are to be used, without bushings, tank lip or radiators involved. The weight of a unit of 2,000-5,000 lb requires the use of a 10-ton crane while heavier constructions necessitate the use of a larger crew to operate a 25-ton crane.Our <a href=\"\/ja\/blog\/transformer-transportation-and-rigging\/\">transformer transportation and rigging guide<\/a> covers the equipment and safety rules by weight class.<\/li>\n<li>Foundation and floor loading: prepare the pad or the floor to be capable of bearing the weight of the transformer, plus the additional weight of the casing if there is any. The oil-filled construction needs the foundation to be able to bear the total weight of a transformer filled with oil, which is large if compared to its empty weight. Our <a href=\"\/ja\/blog\/transformer-foundation-and-floor-loading\/\">foundation and floor loading guide<\/a> covers the concrete design basics for mid-size units.<\/li>\n<\/ul>\n<p>Rule for budgeting: installation costs and freight for a transformer with a power of 500 kVA account for 15-30% of the equipment price; the mass of the construction is the main reason for such costs.<\/p>\n<h2>\u3088\u304f\u3042\u308b\u8cea\u554f<\/h2>\n<h3>How much does a 1000 kVA transformer weigh?<\/h3>\n<p>The average weight of a 1,000 kVA transformer is around 3.1-4.5 tons (or 6,800-9,900 lb) when it comes to oil-filled models and about 2.5-3.5 tons for dry equipment models, while the total weight is dependent on such parameters as the voltage class as well as the manufacturer. Typically 10 kV oil-filled Chinese transformers are believed to weigh around 3.1 to 3.6 tons; the more efficient and heavier the transformers, the higher their voltage class is going to be.<\/p>\n<h3>What is the weight of a 500 kVA generator?<\/h3>\n<p>The average weight of a diesel generator rated at 500 kVA (roughly 400-450 kW) will vary in the range from 4,000 to 8,000 kg (4 to 8 tons) while taking into account the base, radiator, and fuel tank weight. The diesel generator model is generally heavier than the 500 kVA transformer; it is due to the fact that it consists of heavy machinery like the engine or alternator among other things. The weight of the machine will depend on the manufacturer as well as the enclosure.<\/p>\n<h3>What are the specifications for a 500 kVA transformer?<\/h3>\n<p>Normally, a 500-kVA transformer with standard parameters might have the following specifications: 10 kV \/ 0.4 kV or 11 kV\/0.433 kV, three-phase, 50\/60 Hz, Dyn11 vector group, no-load loss around 0.68-0.98 kW, load loss around 5.7-6.2 kW, no-load current around 1%, impedance varying from 4% to 6%, the total weight of the equipment being around 1.8 tons and oil weight of 0.3-0.5 tons. The dry-type alternative of the SCB type will have F-class insulation; its weight is going to be around 1.2 -1.8 tons and can be installed indoors.<\/p>\n<h3>How much does a power transformer weigh?<\/h3>\n<p>Power transformers are heavier than distribution transformers; for example, the weight of a transformer rated at 10 MVA approximates 15-25 tons, while a 50 MVA transformer is from 40 to 65 tons heavy and a transformer from the 220 kV range will weigh around 80-150 tons. It should be noted that the distribution transformer is the lightest one; thus the weight scales according to the rating and voltage class of transformers.<\/p>\n<h2>\u53c2\u8003\u6587\u732e<\/h2>\n<ul>\n<li><a href=\"https:\/\/transformer4u.com\/transformer-weight-chart-by-kva-complete-reference-table-2026\/\" rel=\"nofollow noopener\" target=\"_blank\">Transformer4U \u2014 Transformer weight chart by kVA with estimation formulas<\/a><\/li>\n<li><a href=\"https:\/\/b2bwiki.baidu.com\/article\/d0r2pq9ftjsv1cjniqgg\" rel=\"nofollow noopener\" target=\"_blank\">Baidu B2B Wiki \u2014 Transformer weights by capacity (GB\/T reference data)<\/a><\/li>\n<li><a href=\"https:\/\/wcheng.nmbcp.com\/news\/15534.html\" rel=\"nofollow noopener\" target=\"_blank\">Runsen Transformer \u2014 S11 series weight reference by kVA<\/a><\/li>\n<li><a href=\"https:\/\/es.made-in-china.com\/co_2d2c2d439714f097\/product_500kVA-Oil-Immersed-Industrial-Transformer-10kv-0-4kv-50Hz-Class-H-Insulation_yyggsgrhhg.html\" rel=\"nofollow noopener\" target=\"_blank\">Tianhong Power \u2014 500 kVA oil-immersed transformer technical data (weights, losses)<\/a><\/li>\n<li><a href=\"https:\/\/www.energy.gov\/\" rel=\"nofollow noopener\" target=\"_blank\">US DOE \u2014 Distribution transformer efficiency and design standards<\/a><\/li>\n<\/ul>\n<h2>\u7d50\u8ad6<\/h2>\n<p>The weight of a transformer rated at 500 kVA is estimated. Each dry transformer would weigh anywhere between 1.2 tons to 1.8 tons whereas theoretical calculations of the weight of each oil-immersed transformer would be more since the latter would weigh about 1.8 tons up to 2.5 tons depending, among other factors, on winding material used, efficiency class and the manufacturer of the transformer. Using equations presented in this document, the weight can also be estimated before making plans for the truck, crane or foundation.<\/p>","protected":false},"excerpt":{"rendered":"<p>Weighing up the acquisition of a transformer rated at 500 kVA, one of the essential factors to take into account is the weight of the transformer. The weight of the transformer would dictate the kind of transport vehicle that will be required, crane specifications, foundation, loading and air clearance as well as access to your workshop. However, while requesting the weight of the 500 kVA transformer from two suppliers, you may receive two different weights of 1200 kg and 2500 kg respectively. Are both weights accurate? Yes, both weights are correct as the weight of the transformer would vary depending on the type of fabrication used (oil-immersed and dry-type), the [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":11179,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-11178","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"blocksy_meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/posts\/11178","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/comments?post=11178"}],"version-history":[{"count":4,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/posts\/11178\/revisions"}],"predecessor-version":[{"id":11189,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/posts\/11178\/revisions\/11189"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/media\/11179"}],"wp:attachment":[{"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/media?parent=11178"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/categories?post=11178"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/subian-electric.com\/ja\/wp-json\/wp\/v2\/tags?post=11178"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
