Daher war der Austausch oder die Aufr\u00fcstung von Transformatoren kein Wohlt\u00e4tigkeitsfall, sondern einfach der g\u00fcnstigste Strom, den das Versorgungsunternehmen jemals erwerben konnte. Gleichzeitig las die Nachhaltigkeitsdirektorin des chinesischen staatlichen Netzbetreibers \u00fcber dieselben Entwicklungen, jedoch aus einer anderen Perspektive: Bei der Erstellung von Beschaffungsausschreibungen wurden die Umweltfaktoren ber\u00fccksichtigt, und alle Fabriken, die keinen Nachweis erbringen konnten, dass ihre Produktionsprozesse \u201ckohlenstofffrei\u201d waren, verschwanden von der Bieter-Liste. So lebten beide Frauen durch denselben globalen Wandel, und das sind die heutigen dualen Kohlenstoffziele, die die Arbeit der gesamten Transformatorenindustrie beeinflussen.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-10966\" src=\"https:\/\/subian-electric.com\/wp-content\/uploads\/2026\/08\/Four-Levers-of-Green-Transformation.webp\" alt=\"\" width=\"1448\" height=\"1086\" \/><\/p>\n<h2 id=\"what-is\">Was die dualen Kohlenstoffziele sind<\/h2>\n<p>Die dualen Kohlenstoffziele sind Chinas wichtigste Klimaverpflichtungen: der H\u00f6hepunkt der Kohlendioxidemissionen bis 2030 und die Erreichung der Kohlenstoffneutralit\u00e4t bis 2060. Diese Ziele wurden im September 2020 angek\u00fcndigt und haben die Rolle der Leitprinzipien f\u00fcr die Fertigungs-, Energieerzeugungs- und Exportindustrien des Landes \u00fcbernommen. Der entwickelte \u201c1+N\u201d-Politikrahmen verbindet die nationalen Ziele mit branchenspezifischen Zielen wie Energieproduktion, gr\u00fcne Fertigung, Energieeffizienz und anderen Mechanismen wie Kohlenstoffpreisen und gr\u00fcnen Stromzertifikaten.<\/p>\n<p>Was die Transformatorenindustrie betrifft, stellen die dualen Kohlenstoffziele kein abstraktes Konzept dar. Jede Phase der Prozesskette soll die Emissionen messen und begrenzen, die sie erzeugt: Der Stahl und das Kupfer, die zur Herstellung eines Transformators verwendet werden, enthalten bereits verk\u00f6rperten Kohlenstoff; die Fabrik ben\u00f6tigt Energie; zudem nutzt ein Transformator seinen Anteil an jedem Megawatt, das von ihm verarbeitet wird.<\/p>\n<table>\n<thead>\n<tr>\n<th>Meilenstein<\/th>\n<th>Datum<\/th>\n<th>Konsequenz der Transformatorenindustrie<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Ank\u00fcndigung der dualen Kohlenstoffziele<\/td>\n<td>September 2020<\/td>\n<td>Rahmen festgelegt; sektorale Pl\u00e4ne beginnen<\/td>\n<\/tr>\n<tr>\n<td>GB 20052 Effizienzklassen in Kraft<\/td>\n<td>2020\u20132021<\/td>\n<td>Klasse 2 wird zur Basislinie f\u00fcr Verteiltransformatoren<\/td>\n<\/tr>\n<tr>\n<td>Kohlenstoffspitzenziel<\/td>\n<td>Vor 2030<\/td>\n<td>Reduzierung der Netzverluste beschleunigt; gr\u00fcne Beschaffung erweitert sich<\/td>\n<\/tr>\n<tr>\n<td>Ziel der Kohlenstoffneutralit\u00e4t<\/td>\n<td>Vor 2060<\/td>\n<td>Amorphe Kerne und gr\u00fcne Fabriken werden zum Standard<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Die Daten sind wichtig, da Beschaffungsentscheidungen, die jetzt getroffen werden, f\u00fcr 25\u201335 Jahre bindend sind \u2014 ein heute bestellter Transformator wird weiterhin auf den Horizont der Kohlenstoffneutralit\u00e4t hinarbeiten.<\/p>\n<h2 id=\"why-transformers\">Warum Transformatoren im Zentrum des Problems stehen<\/h2>\n<p>Transformatoren spielen eine Schl\u00fcsselrolle in den meisten Prozessen innerhalb des Elektrizit\u00e4tssystems \u2014 von der Erzeugung \u00fcber die \u00dcbertragung und Verteilung bis hin zur Endnutzung. Nationale Stromnetze verwenden Hunderttausende von Transformatoren, wobei jeder einzelne Ineffizienzen aufweist, die zu Verlusten bei der Nutzung von Elektrizit\u00e4t f\u00fchren.<br \/>\nUntersuchungen zu den Verlusten in Transformatoranlagen zeigen, dass die Verluste bei der Elektrizit\u00e4ts\u00fcbertragung etwa 5-8% erreichen. Das bedeutet auch, dass die Verluste der Transformatoren einen erheblichen Teil dieser Zahl ausmachen.<br \/>\nSolche Verluste sind aus zwei Gr\u00fcnden signifikant. Erstens handelt es sich um verschwendete Elektrizit\u00e4t im System, die von einem kohlenstoffarmen System nicht toleriert werden kann, da jeder Watt Elektrizit\u00e4t produziert, \u00fcbertragen und bezahlt wird. Zweitens ist es eine konzentrierte und nachweisbare Verlustquelle, da es keine Probleme gibt, Transformatoren zu finden und zu reparieren, im Gegensatz zu anderen Arten von Verlusten im Elektrizit\u00e4tssystem. Deshalb ist die Effizienz von Transformatoren eines der h\u00e4ufigsten Themen, die in verschiedenen Strategien zur Energieeffizienz und Kohlenstoffreduzierung ber\u00fccksichtigt werden, wie zum Beispiel im EU-Ecodesign und im chinesischen Bewertungssystem.<\/p>\n<h2 id=\"losses\">Das Verlustinventar: Wo die Emissionen von Transformatoren leben<\/h2>\n<p>Transformatorverluste lassen sich in zwei Kategorien unterteilen, und die Kohlenstoffbilanz behandelt sie unterschiedlich:<\/p>\n<table>\n<thead>\n<tr>\n<th>Verlusttyp<\/th>\n<th>Ursache<\/th>\n<th>Wann es auftritt<\/th>\n<th>Kohlenstoffauswirkung<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Leerlauf (Kern)verlust<\/td>\n<td>Magnetisierung des Stahlkerns<\/td>\n<td>24 Stunden am Tag, w\u00e4hrend er unter Spannung steht<\/td>\n<td>Dominant in leicht belasteten Netzen; konstante Emissionen<\/td>\n<\/tr>\n<tr>\n<td>Last (Kupfer)verlust<\/td>\n<td>Strom durch Wicklungen<\/td>\n<td>Skaliert mit dem Quadrat der Last<\/td>\n<td>Dominant bei hohem Lastfaktor<\/td>\n<\/tr>\n<tr>\n<td>Verk\u00f6rperter Kohlenstoff<\/td>\n<td>Stahl-, Kupfer-, \u00d6lproduktion<\/td>\n<td>Bei der Herstellung<\/td>\n<td>Einmalig; 5\u201315% der Lebenszyklusemissionen f\u00fcr eine langlebige Einheit<\/td>\n<\/tr>\n<tr>\n<td>Lebensende<\/td>\n<td>\u00d6lentsorgung, Recycling<\/td>\n<td>Bei der Stilllegung<\/td>\n<td>Reduziert durch Ester\u00f6l und recycelbare Designs<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Was daraus klar wird, ist, dass in den meisten F\u00e4llen der w\u00e4hrend des Lebenszyklus von Transformatoren emittierte Kohlenstoff auf Leerlaufverluste zur\u00fcckzuf\u00fchren ist, da Transformatoren kontinuierlich mit Elektrizit\u00e4t versorgt werden, aber selten mit voller Kapazit\u00e4t genutzt werden. Zum Beispiel wird ein Transformator mit einer Nennleistung von 400 kVA, der mit einer durchschnittlichen Last von 30% l\u00e4uft, aufgrund von Verlusten durch seinen Kern mehr Energie verbrauchen als aufgrund von Verlusten durch seine Wicklungen in den meisten Monaten. Genau aus diesem Grund konzentrierten sich die ersten Regelungen im Bereich energieeffizienter Transformatoren auf Kernverluste.<\/p>\n<h2 id=\"technology\">Technologische Hebel: Kerne, \u00d6le und Design<\/h2>\n<p>Technologie ist der Bereich, in dem die gr\u00fcne Transformation der Transformatorenindustrie gewonnen wird. Vier Hebel, grob nach Einfluss auf den Leerlaufverlust geordnet:<\/p>\n<table>\n<thead>\n<tr>\n<th>Technologie<\/th>\n<th>Einfluss auf den Leerlaufverlust<\/th>\n<th>Erstkosten-Effekt<\/th>\n<th>Kohlenstoffbegr\u00fcndung<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>High-permeability GOES, 0.23\u20130.27 mm<\/td>\n<td>15\u201325% lower than standard grade<\/td>\n<td>+3\u20136%<\/td>\n<td>Less steel loss per kWh delivered<\/td>\n<\/tr>\n<tr>\n<td>Amorpher Metallkern<\/td>\n<td>60\u201370% lower than conventional<\/td>\n<td>+20\u201340%<\/td>\n<td>Biggest single lever for 24\/7 operation<\/td>\n<\/tr>\n<tr>\n<td>Nat\u00fcrlicher Ester (pflanzliches) \u00d6l<\/td>\n<td>Neutral electrically<\/td>\n<td>+10\u201315%<\/td>\n<td>Biodegradable, lower fire risk, lower embodied carbon vs mineral oil<\/td>\n<\/tr>\n<tr>\n<td>Low-loss winding (larger conductor)<\/td>\n<td>Load loss down 10\u201320%<\/td>\n<td>+2\u20135%<\/td>\n<td>Relevant for heavily loaded transformers<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Amorphous alloy is the flagship technology of the dual-carbon era in distribution transformers. Because the ribbon&#8217;s no-load loss is dramatically lower, an amorphous-core 1,000 kVA unit saves roughly 500\u2013700 W versus a conventional high-efficiency unit \u2014 about $440\u2013$610\/year at $0.10\/kWh, or $5,000\u2013$7,000 in present value over 15 years. It is the technology most consistently named in Chinese incentive programmes and the one most likely to become mandatory as grade 1 standards tighten.<\/p>\n<h2 id=\"manufacturing\">Green Manufacturing: The Factory&#8217;s Own Footprint<\/h2>\n<p>The dual carbon objective extends into the production process. The green manufacturing system assesses factories on the basis of their energy consumption per output as well as on the amount of renewable energy used and the efficient use of resources such as water, recycling of waste products, and emissions of pollutants. Manufacturers are seeking this certification not only because of the label it gives them but also because procurement by state grid and utilities prefers suppliers that have the certification.<br \/>\nThe measures being taken at the factory level are as follows:<\/p>\n<p>Energy-drying ovens and test floors operating on power from renewable sources, which reduces emissions in scope one and scope two.<br \/>\nRecycling and reusing oil, steel leftovers, and copper scrap from winding and core operations.<br \/>\nInstallation of metering machines for measuring energy consumption throughout the production process and obtaining information about emissions before the company submits an annual report.<br \/>\nUtilization of eco-friendly ester oils both in the workshops and as a construction option for the products.<br \/>\nThe listed operations influence the degree of emissions produced while producing transformers \u2014 which constitutes 5-15% of their total life-cycle emissions, thus being insignificant for a single piece but remarkable for the annual output of thousands of transformers and increasingly becoming a requirement for the suppliers applying for green tenders.<\/p>\n<h2 id=\"policy\">Policy Levers: Grades, Tenders, and Subsidies<\/h2>\n<p>The translation of technology into market status takes place with the help of policy. The key drivers of the process consist in:<\/p>\n<p>Efficiency ratings: GB 20052 ratings that range from 1 to 3 for distribution transformers, where the minimum efficiency standard is grade 2, while already in many public procurement programs, the maximum efficiency class, i.e., grade 1 (amorphous type) is either a requirement or qualifies for financial support.<br \/>\nMinimum efficiency standards in trade: EU Ecodesign standard 2019\/1783 is a major legislative act regulating minimum efficiency for street lamps (the standard will come into force from mid-July of 2024), while under DOE regulations, meeting the requirements will guarantee market entrance.<br \/>\nGreen procurement score: in tenders, electricity distribution companies weigh efficiency rating, type of oil used, and factory certification, which constitutes approximately 5-10% of the total score.<br \/>\nCarbon markets and certificates: the efficiency of green certificates and possible carbon pricing mechanisms increases the effectiveness of losses avoided with the passage of time.<\/p>\n<p>The ratchet effect takes place with the present upgrades of the ratings pattern raising the base, while the operation of incentives pushes top efficiency technologies in mass production, which reduces their price and makes the next tightening affordable.<\/p>\n<h2 id=\"roadmap\">A Roadmap for the Green Transformation<\/h2>\n<p>For an organization holding a transformer fleet, the green transformation follows a practical sequence:<\/p>\n<table>\n<thead>\n<tr>\n<th>Fleet category<\/th>\n<th>Typical condition<\/th>\n<th>Empfohlene Ma\u00dfnahme<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Pre-2000 units, high no-load loss<\/td>\n<td>1,500\u20132,100 W per 1,000 kVA<\/td>\n<td>Replace first \u2014 best loss and carbon return<\/td>\n<\/tr>\n<tr>\n<td>2000\u20132010 units, moderate loss<\/td>\n<td>Within older standards<\/td>\n<td>Replace or repurpose; prioritize by load factor<\/td>\n<\/tr>\n<tr>\n<td>Modern grade 2 units<\/td>\n<td>700\u20131,100 W per 1,000 kVA<\/td>\n<td>Keep; optimize taps and parallel operation<\/td>\n<\/tr>\n<tr>\n<td>Grade 1 \/ amorphous units<\/td>\n<td>350\u2013500 W per 1,000 kVA<\/td>\n<td>Keep and monitor; benchmark as best practice<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Take inventory and categorize from the transformer database all specifications of transformers including nameplate, age, losses, load characteristics, and location.<br \/>\nApply loss ranking for prioritization: apply loss capitalization methodology for assessing units on annual cost of no-load plus load loss; generally, the least 20% of units account for 50% and more of the entire fleet losses.<br \/>\nReplace the most inefficient first: replacement of transformers from the 1990s and early 2000s is focused on \u201cA\u201d-level replacements utilizing amorphous cores in instances when they are justified by load and hours of operation.<br \/>\nConduct operational optimization: re-taps, re-balancing of the units connected in schools, and careful sizing of units will entail minimal cost and provide for very quick outcomes and effects.<br \/>\nCollect and claim: keep routine testing reports, efficiency class evidence, and any eligible green subsidies or procurement preferences provided federal grants that are applicable.<\/p>\n<h2 id=\"brands\">Green Transformer Options and Prices<\/h2>\n<p>Indicative pricing for a 1,000 kVA 10\/0.4 kV energy-saving distribution transformer, FOB by brand and technology:<\/p>\n<table>\n<thead>\n<tr>\n<th>Marke<\/th>\n<th>Herkunft<\/th>\n<th>Grade 2 (GOES)<\/th>\n<th>Grade 1 \/ amorphous core<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Hitachi Energie<\/td>\n<td>Japan\/Weltweit<\/td>\n<td>$9.000\u2013$12.500<\/td>\n<td>$12.500\u2013$18.000<\/td>\n<\/tr>\n<tr>\n<td>ABB<\/td>\n<td>Schweiz\/Weltweit<\/td>\n<td>$8.500\u2013$12.000<\/td>\n<td>$12.000\u2013$17.000<\/td>\n<\/tr>\n<tr>\n<td>Siemens Energie<\/td>\n<td>Deutschland\/Weltweit<\/td>\n<td>$8.000\u2013$11.500<\/td>\n<td>$11.500\u2013$16.500<\/td>\n<\/tr>\n<tr>\n<td>Schneider Electric<\/td>\n<td>Frankreich\/Weltweit<\/td>\n<td>$7.500\u2013$11.000<\/td>\n<td>$11.000\u2013$15.500<\/td>\n<\/tr>\n<tr>\n<td>Jiangsu Subian Electric Power<\/td>\n<td>China<\/td>\n<td>$4.000\u2013$7.000<\/td>\n<td>$5.500\u2013$9.500<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Prices vary with loss class, tap changer, ester-oil option, copper prices, and delivery terms; treat these as planning ranges, not firm quotes.<\/p>\n<p>Global brands anchor the premium tier with deep service networks and extensive type-test programs.

The objectives drive sectoral policy through a \u201c1 + N\u201d approach that encompasses energy, industry, transportation, and green manufacturing, with measures such as transformer efficiency ratings, green factory certification, and carbon market approaches.<\/p>\n<h3>How much energy does an inefficient transformer waste?<\/h3>\n<p>A 1,000 kVA transformer from the 1990s typically wastes 1,500\u20132,100 W at no load \u2014 about 13,000\u201318,000 kWh per year, worth $1,050\u2013$1,800 at $0.08\u2013$0.10\/kWh. A modern grade 2 unit halves that and an amorphous-core unit cuts it to 350\u2013500 W, about a quarter of the original.<\/p>\n<h3>Is an amorphous core transformer worth the premium?<\/h3>\n<p>In continuously loaded applications, yes. The 20\u201340% first-cost premium is recovered through 60\u201370% lower no-load loss in 4\u20138 years at typical industrial tariffs, and the saving compounds over 25\u201335 years of life. In lightly loaded, seasonal sites, a grade 2 GOES unit is often the value optimum.<\/p>\n<h3>How much do green transformers cost?<\/h3>\n<p>A 1,000 kVA grade 2 unit runs about $4,000\u2013$7,000 FOB from Chinese manufacturers; grade 1 amorphous-core versions run $5,500\u2013$9,500. Premium European and Japanese brands are typically 50\u201380% higher. Prices vary with accessories, ester-oil option, and copper prices.<\/p>\n<h3>What is a green factory in the transformer industry?<\/h3>\n<p>A green factory is a manufacturing site certified under China&#8217;s green manufacturing system for low energy use per unit output, renewable energy share, water and waste management, and recycling. For transformer buyers, a green-factory certificate signals lower embodied carbon and is increasingly weighted in utility and government tenders.<\/p>\n<h2 id=\"references\">Referenzen<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.gov.cn\/zhengce\/2021-10\/24\/content_5644613.htm\" rel=\"nofollow noopener\" target=\"_blank\">China&#8217;s dual carbon work programme (CN)<\/a> \u2014 The official policy framework for peaking and neutrality targets.<\/li>\n<li><a href=\"https:\/\/openstd.samr.gov.cn\/\" rel=\"nofollow noopener\" target=\"_blank\">GB 20052: Energieeffizienzklassen f\u00fcr Leistungstransformatoren<\/a> \u2014 The efficiency grade standard at the centre of China&#8217;s transformer policy.<\/li>\n<li><a href=\"https:\/\/eur-lex.europa.eu\/legal-content\/EN\/TXT\/?uri=CELEX:32019R1783\" rel=\"nofollow noopener\" target=\"_blank\">EU-Ecodesign-Verordnung 2019\/1783<\/a> \u2014 EU transformer efficiency requirements aligned with the same direction.<\/li>\n<li><a href=\"https:\/\/webstore.iec.ch\/publication\/637\" rel=\"nofollow noopener\" target=\"_blank\">IEC 60076-1: Leistungstransformatoren \u2013 Allgemeines<\/a> \u2014 International testing baseline for transformer performance.<\/li>\n<li><a href=\"https:\/\/www.iea.org\/topics\/energy-efficiency\" rel=\"nofollow noopener\" target=\"_blank\">IEA-Programm zur Energieeffizienz<\/a> \u2014 Data on grid losses and transformer efficiency policy.<\/li>\n<li><a href=\"https:\/\/www.miit.gov.cn\/\" rel=\"nofollow noopener\" target=\"_blank\">MIIT green manufacturing system<\/a> \u2014 China&#8217;s green factory evaluation and certification framework.<\/li>\n<li><a href=\"https:\/\/subian-electric.com\/de\/\" rel=\"nofollow\">Offizielle Website von Jiangsu Subian Electric Power<\/a> \u2014 Green factory certification and energy-saving transformer range.<\/li>\n<\/ul>\n<h2 id=\"conclusion\">Fazit<\/h2>\n<p>Die <strong>dual carbon<\/strong> goals give the transformer industry a clear destination and a hard timetable.
