class=\"wp-block-heading has-text-align-left\">A Progressive Integration Within Le Cosinus<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">From <strong>2017<\/strong>, the company <strong>Constructions \u00c9lectriques Le Cosinus<\/strong> became the managing entity of <strong>ABE<\/strong>, marking the beginning of a closer relationship between the two organisations. \nThis integration was legally completed through a <strong>merger by absorption<\/strong>, resulting in the official removal of ABE from the company register on <strong>18 March 2021<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">ABE\u2019s activities and expertise were fully integrated into Le Cosinus, strengthening the group\u2019s technical and industrial capabilities.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-left\">The Transfer of Recognised Technical Expertise<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The integration of ABE enabled Le Cosinus to further develop its expertise in specialised technical fields, particularly in <strong>winding technologies, customised transformers, and power electronics<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph translation-block\">This transfer of knowledge is now reflected in several areas of expertise developed by Le Cosinus, including high-value-added products such as <a href=\"https:\/\/www.lecosinus.fr\/en\/other-products\/ferrite-high-frequency-transformers\/\" data-type=\"link\" data-id=\"https:\/\/www.lecosinus.fr\/autres\/transformateurs-hautes-frequences-ferrites\/\" target=\"_self\">high-frequency ferrite-core transformers.<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike many market players, who are often specialised either in low-frequency or high-frequency applications, Le Cosinus now benefits from a combined skill set allowing it to address more complex technical requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This expertise is based on:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A dedicated workshop for high-frequency and high-voltage winding;<\/li>\n\n\n\n<li>Prototyping and small-series production capabilities;<\/li>\n\n\n\n<li>The use of a wide range of materials (magnetic cores, ferrites, Litz wires, etc.);<\/li>\n\n\n\n<li>Precise adaptation to customers\u2019 technical requirements.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The solutions developed are intended for demanding industrial sectors such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Railway;<\/li>\n\n\n\n<li>Aerospace;<\/li>\n\n\n\n<li>Medical applications;<\/li>\n\n\n\n<li>Laser systems and defence technologies.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Industrial Continuity Serving Our Customers <\/h2>\n\n\n\n<p class=\"wp-block-paragraph translation-block\">The legal disappearance of ABE does not represent the end of its  <a href=\"https:\/\/www.lecosinus.fr\/en\/100-percent-french-manufacturing-a-mark-of-trust\/\" data-type=\"link\" data-id=\"https:\/\/www.lecosinus.fr\/une-fabrication-100-francaise-un-gage-de-confiance\/\" target=\"_self\">expertise<\/a>. On the contrary, it ensures the long-term preservation of its know-how within a broader and more comprehensive organisation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Today, Le Cosinus builds on this heritage to offer:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>An expanded range of transformers and electrical components; <\/li>\n\n\n\n<li>Customised solutions adapted to complex industrial projects;<\/li>\n\n\n\n<li>Enhanced innovation capabilities through the combination of complementary expertise.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Cette volont\u00e9 de pr\u00e9server les savoir-faire industriels se retrouve \u00e9galement dans <a href=\"https:\/\/www.lecosinus.fr\/en\/montelem-heritage-over-50-years-of-experience-in-ignition-transformer-manufacturing\/\">l\u2019h\u00e9ritage Montelem et son expertise en transformateurs d\u2019allumage<\/a>, repris par Le Cosinus.<\/p>\n\n\n\n<div class=\"hs-cta-embed hs-cta-simple-placeholder hs-cta-embed-185420320831\" style=\"max-width:100%;max-height:100%;width:700px;height:239.53125px\" data-hubspot-wrapper-cta-id=\"185420320831\">\r\n  <a href=\"https:\/\/cta-service-cms2.hubspot.com\/web-interactives\/public\/v1\/track\/redirect?encryptedPayload=AVxigLJ%2B8uzXIlYd5F1Cg72GDEo4S1p9zzkqyLAlT3McWV%2BDNRWsrtcQFwhBihGlWDL3nSWdQscvugwJIEM%2Blo0sWyqvQjAIafWdESsEYmcGkml4PxESyXNVWWZLqCNHgrHd%2BIsg8qUJHAayrn2LojP7LZPyflwCywOPcg8taJdeZJCXxpOTHuE%3D&amp;webInteractiveContentId=185420320831&amp;portalId=48243687\" target=\"_blank\" rel=\"noopener\">\r\n    <img decoding=\"async\" alt=\"Demande de devis Saisissez votre r&eacute;f&eacute;rence produit ou indiquer les caract&eacute;ristiques du produit recherch&eacute; &nbsp;\" loading=\"lazy\" src=\"https:\/\/no-cache.hubspot.com\/cta\/default\/48243687\/interactive-185420320831.png\" style=\"height: 100%;width: 100%;object-fit: fill\" \/>\r\n  <\/a>\r\n<\/div>","protected":false},"excerpt":{"rendered":"<p>La soci\u00e9t\u00e9 ABE (SIREN : 433 386 794) \u00e9tait une entreprise fran\u00e7aise sp\u00e9cialis\u00e9e dans la fabrication et la commercialisation de mat\u00e9riels \u00e9lectrotechniques, et notamment de transformateurs, transformateurs haute fr\u00e9quences et r\u00e9gulateurs \u00e9lectriques.
