Processus de production<\/strong><\/p><p><strong><b>1. Fabrication de noyaux en fer<\/b><\/strong>: Le \u201c c\u0153ur du circuit magn\u00e9tique \u201d du transformateur. Pour les noyaux traditionnels en t\u00f4le d\u2019acier au silicium, notre entreprise adopte g\u00e9n\u00e9ralement la m\u00e9thode d\u2019empilage en chevauchement par paliers combin\u00e9e \u00e0 une technologie moderne, et recourt de plus en plus au proc\u00e9d\u00e9 de culasse sup\u00e9rieure non lamin\u00e9e, qui permet de r\u00e9duire efficacement les pertes \u00e0 vide et le bruit. Des tiges isolantes sont ins\u00e9r\u00e9es entre les couches du noyau en fer afin de rapprocher la section transversale de la colonne du noyau d\u2019un cercle, ce qui permet de mieux soutenir les enroulements. Quant aux noyaux en alliage amorphe, ils se caract\u00e9risent par des pertes \u00e0 vide extr\u00eamement faibles, mais le mat\u00e9riau est fragile, dur et sensible aux contraintes m\u00e9caniques.<\/p><p><strong><b>2. Enroulement de bobines<\/b><\/strong>: Le \u201c c\u0153ur \u201d du transformateur. Les fils sont principalement en cuivre sans oxyg\u00e8ne, recouverts d\u2019une couche isolante \u00e0 l\u2019ext\u00e9rieur. Un dispositif de tension est utilis\u00e9 pendant le processus d\u2019enroulement afin de garantir que les bobines soient bien serr\u00e9es. En fonction de la tension et de la capacit\u00e9, les enroulements peuvent prendre diff\u00e9rentes formes, telles que le type en couches, le type continu et le type en spirale. Pour limiter les pertes, on utilise souvent des fils de grande section pour les enroulements de grande capacit\u00e9 ou \u00e0 courant \u00e9lev\u00e9. Apr\u00e8s l\u2019enroulement, les bobines doivent subir un s\u00e9chage \u00e0 pression constante, puis un ajustement de leur hauteur une fois sorties du four, afin de garantir que leurs dimensions r\u00e9pondent aux exigences de conception et qu\u2019elles pr\u00e9sentent une r\u00e9sistance m\u00e9canique suffisante.<\/p><p><strong><b>3. Assemblage du noyau<\/b><\/strong>: Il s'agit d'une \u00e9tape cl\u00e9 pour assembler le noyau de fer et les bobines en un seul ensemble. Les technologies modernes privil\u00e9gient l'assemblage monobloc (assemblage int\u00e9gral) : cela consiste d'abord \u00e0 assembler les enroulements de chaque phase, les pi\u00e8ces isolantes, etc., pour former un ensemble, puis \u00e0 les monter en une seule fois sur la colonne du noyau de fer. Les connexions des fils utilisent principalement des proc\u00e9d\u00e9s de pressage \u00e0 froid ou de soudage au cuivre phosphoreux afin de garantir la fiabilit\u00e9 des connexions. Le serrage des boulons de toutes les pi\u00e8ces de connexion \u00e9lectrique doit \u00eatre effectu\u00e9 avec un contr\u00f4le du couple. Apr\u00e8s l\u2019assemblage, le noyau subit un traitement de s\u00e9chage (tel que le s\u00e9chage en phase gazeuse au charbon) afin d\u2019\u00e9liminer compl\u00e8tement l\u2019humidit\u00e9.<\/p><p><strong><b>4. Fabrication et assemblage final des r\u00e9servoirs d'huile<\/b><\/strong>: Le r\u00e9servoir d'huile doit r\u00e9sister au vide (essai de d\u00e9tection des fuites). Apr\u00e8s le traitement de s\u00e9chage du noyau, celui-ci doit \u00eatre plac\u00e9 rapidement dans le r\u00e9servoir afin de limiter l\u2019absorption d\u2019humidit\u00e9. L\u2019assemblage final comprend l\u2019installation des travers\u00e9es, des conservateurs d\u2019huile, des changeurs de prises et d\u2019autres composants. Le remplissage sous vide est essentiel pour garantir les performances d\u2019isolation. Apr\u00e8s le remplissage, un temps de repos suffisant est n\u00e9cessaire pour permettre \u00e0 l\u2019huile de p\u00e9n\u00e9trer et d\u2019\u00e9vacuer les bulles d\u2019air r\u00e9siduelles.<\/p><p><strong><b>5. Essais et contr\u00f4les en usine<\/b><\/strong>: Il s'agit du contr\u00f4le qualit\u00e9 final avant la livraison du produit. Des essais de routine sont obligatoires pour chaque unit\u00e9 ; ils comprennent notamment la mesure de la r\u00e9sistance en courant continu des enroulements, la mesure du rapport de tension et la v\u00e9rification de l'\u00e9tiquette indiquant le groupe de raccordement, ainsi que l'essai de tenue \u00e0 la tension \u00e0 la fr\u00e9quence du r\u00e9seau, etc. Les essais de type visent \u00e0 v\u00e9rifier des caract\u00e9ristiques de conception sp\u00e9cifiques, telles que les essais d'impulsion de foudre et les essais d'\u00e9l\u00e9vation de temp\u00e9rature. Des essais sp\u00e9ciaux, tels que la mesure du niveau sonore et les essais de r\u00e9sistance aux courts-circuits (g\u00e9n\u00e9ralement calcul\u00e9s et v\u00e9rifi\u00e9s), sont effectu\u00e9s conform\u00e9ment aux exigences du client ou aux normes en vigueur.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div id=\"e-n-tab-content-649863464\" role=\"tabpanel\" aria-labelledby=\"e-n-tab-title-649863464\" data-tab-index=\"4\" style=\"--n-tabs-title-order: 4;\" class=\"elementor-element elementor-element-265fa39 e-con-full e-flex e-con e-child\" data-id=\"265fa39\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-73d198a elementor-widget elementor-widget-heading\" data-id=\"73d198a\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Caract\u00e9ristiques techniques<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-de4a9c0 elementor-widget elementor-widget-n-accordion\" data-id=\"de4a9c0\" data-element_type=\"widget\" data-settings=\"{&quot;default_state&quot;:&quot;all_collapsed&quot;,&quot;max_items_expended&quot;:&quot;multiple&quot;,&quot;n_accordion_animation_duration&quot;:{&quot;unit&quot;:&quot;ms&quot;,&quot;size&quot;:400,&quot;sizes&quot;:[]}}\" data-widget_type=\"nested-accordion.default\">\n\t\t\t\t\t\t\t<div class=\"e-n-accordion\" aria-label=\"Accordion.

Product Advantages<\\\/b><\\\/strong><\\\/p><p><strong>\\u00a01.Flexible Installation, Adaptable to Complex Outdoor Environments<\\\/strong><\\\/p><p>\\u2460Lightweight Design for Easy DeploymentPole-mounted transformers usually have a capacity of 50kVA~630kVA, with small size and light weight (compared to indoor substation transformers). They can be directly installed on utility poles, pole racks, or simple brackets without the need to build dedicated power distribution rooms or foundations. They are particularly suitable for space-constrained areas such as rural areas, suburbs, and streets.<\\\/p><p>\\u2461Strong Environmental AdaptabilityThe enclosure adopts a sealed structure with anti-corrosion, rainproof, and sunproof properties (such as corrugated oil tanks and fully sealed designs), which can withstand harsh outdoor environments such as high temperatures, severe cold, humidity, and dust. The operational reliability is not significantly affected by natural conditions.<\\\/p><p>\\u2462Convenient Site Selection and Wide Coverage RangeSites can be flexibly selected according to user distribution, and the transformer can be installed close to the load center. This shortens the low-voltage line distance, reduces line losses and voltage drops, and improves the power supply quality for end users.<\\\/p><p><strong>2.High Energy Efficiency, Reducing Distribution Losses<\\\/strong><\\\/p><p>\\u2460Low-Loss Iron Core and Winding DesignHigh magnetic permeability silicon steel sheets and low-resistance copper wires\\\/aluminum wires are used to reduce iron loss (no-load loss) and copper loss (load loss).<\\\/p><p>\\u2461Optimized Heat Dissipation StructureDesigns such as corrugated oil tanks and finned radiators increase the heat dissipation area. Combined with natural air cooling (no forced cooling device required), they ensure efficient heat dissipation of the transformer under rated load and avoid efficiency reduction caused by overheating.<\\\/p><p>\\u2462Adaptation to Light-Load CharacteristicsPole-mounted transformers mainly serve residential and small commercial loads, with large fluctuations in load rate. Their design focuses on reducing losses during light-load operation, further improving comprehensive energy efficiency.<\\\/p>\",\"_padding\":{\"unit\":\"px\",\"top\":\"20\",\"right\":\"0\",\"bottom\":\"0\",\"left\":\"0\",\"isLinked\":false},\"__globals__\":{\"typography_typography\":\"\"},\"typography_typography\":\"custom\",\"typography_font_family\":\"Arial\",\"typography_font_size\":{\"unit\":\"px\",\"size\":16,\"sizes\":[]},\"typography_font_size_mobile\":{\"unit\":\"px\",\"size\":15,\"sizes\":[]},\"paragraph_spacing\":{\"unit\":\"px\",\"size\":16,\"sizes\":[]},\"paragraph_spacing_mobile\":{\"unit\":\"px\",\"size\":10,\"sizes\":[]}},\"elements\":[],\"widgetType\":\"text-editor\"}],\"isInner\":true,\"isLocked\":true},{\"id\":\"764f307\",\"elType\":\"container\",\"settings\":{\"_title\":\"Tab #3\",\"content_width\":\"full\",\"padding\":{\"unit\":\"px\",\"top\":\"50\",\"right\":\"30\",\"bottom\":\"50\",\"left\":\"30\",\"isLinked\":false},\"border_border\":\"solid\",\"border_width\":{\"unit\":\"px\",\"top\":\"1\",\"right\":\"1\",\"bottom\":\"1\",\"left\":\"1\",\"isLinked\":true},\"__globals__\":{\"border_color\":\"globals\\\/colors?id=secondary\"},\"padding_mobile\":{\"unit\":\"px\",\"top\":\"10\",\"right\":\"10\",\"bottom\":\"10\",\"left\":\"10\",\"isLinked\":true}},\"elements\":[{\"id\":\"9872304\",\"elType\":\"widget\",\"settings\":{\"title\":\"Product structure\",\"__globals__\":{\"typography_typography\":\"globals\\\/typography?id=204d764\"}},\"elements\":[],\"widgetType\":\"heading\"},{\"id\":\"b1b2cc5\",\"elType\":\"widget\",\"settings\":{\"editor\":\"<p><strong>\\u2160. Production Process<\\\/strong><\\\/p><p><strong><b>1.Iron Core Manufacturing<\\\/b><\\\/strong>: The \\\"magnetic circuit heart\\\" of the transformer. For traditional silicon steel sheet iron cores, our company generally adopts the step-lap lamination method combined with modern technology, and increasingly applies the non-laminated upper yoke process, which can effectively reduce no-load loss and noise. Insulating rods are filled between the iron core levels to make the cross-section of the iron core column closer to a circle, better supporting the windings. For amorphous alloy iron cores, they are characterized by ultra-low no-load loss, but the material is brittle and hard and sensitive to mechanical stress.<\\\/p><p><strong><b>2.Coil Winding<\\\/b><\\\/strong>: The \\\"circuit core\\\" of the transformer. The wires mostly use oxygen-free copper wires with an insulating layer on the outside. A tensioning device is used during the winding process to ensure the coils are tight. Depending on the voltage and capacity, the windings have various forms, such as layer type, continuous \\u00a0type, and spiral type. To control losses, \\u00a0wires are often used for large-capacity or high-current windings. After winding, the coils need to undergo constant-pressure drying and coil height adjustment after being taken out of the oven to ensure the dimensions meet the design requirements and have sufficient mechanical strength.<\\\/p><p><strong><b>3.Core Assembly<\\\/b><\\\/strong>: This is a key step in combining the iron core and coils into a single unit. Modern technology emphasizes integral (integral assembly), that is, first assembling the windings of each phase, insulating parts, etc., into a whole, and then (assembling) them onto the iron core column at one time. Lead connections mostly use cold pressing or phosphor copper welding processes to ensure reliable connections. The bolt tightening of all electrical connection parts must adopt torque control. After assembly, the core undergoes drying treatment (such as coal gas phase drying) to completely remove moisture.<\\\/p><p><strong><b>4.Oil Tank Manufacturing and Final Assembly<\\\/b><\\\/strong>: The oil tank must withstand vacuum (leak detection test). After the core drying treatment, it needs to be placed into the tank quickly to reduce moisture absorption. Final assembly includes installing bushings, oil conservators, tap changers, and other components. Vacuum oil filling is the key to ensuring insulation performance. After oil filling, sufficient standing time is required to allow the oil to penetrate and discharge residual air bubbles.<\\\/p><p><strong><b>5.Factory Testing and Inspection<\\\/b><\\\/strong>: This is the final quality check before product delivery. Routine tests are mandatory for each unit, including winding DC resistance measurement, voltage ratio measurement and connection group label verification, power frequency voltage withstand test, etc. Type tests are for verifying specific designs, such as lightning impulse tests and temperature rise tests. Special tests such as sound level measurement and short-circuit withstand capability tests (usually calculated and verified) are conducted according to customer requirements or standards.<\\\/p>\",\"_padding\":{\"unit\":\"px\",\"top\":\"20\",\"right\":\"0\",\"bottom\":\"0\",\"left\":\"0\",\"isLinked\":false},\"typography_typography\":\"custom\",\"typography_font_family\":\"Arial\",\"typography_font_size\":{\"unit\":\"px\",\"size\":16,\"sizes\":[]},\"typography_font_size_mobile\":{\"unit\":\"px\",\"size\":15,\"sizes\":[]},\"paragraph_spacing\":{\"unit\":\"px\",\"size\":16,\"sizes\":[]},\"paragraph_spacing_mobile\":{\"unit\":\"px\",\"size\":10,\"sizes\":[]},\"__globals__\":{\"typography_typography\":\"\"}},\"elements\":[],\"widgetType\":\"text-editor\"}],\"isInner\":true,\"isLocked\":true},{\"id\":\"265fa39\",\"elType\":\"container\",\"settings\":{\"_title\":\"Tab
