Product Details<\/strong><\/h4>\n

Our 2500A-3150A contact arm is a heavy-duty conductive component engineered for 10kV\/12kV indoor vacuum circuit breakers and medium voltage switchgear. As a professional China contact arm manufacturer, we deliver high-performance solutions for global power transmission and industrial electrical projects.<\/p>\n<\/div>\n

    \n
  • Mat\u00e9riau et traitement de surface :<\/strong> Crafted from high-conductivity red copper (pure copper), with precision silver plating combined with sulfurization treatment to maximize conductivity, corrosion resistance, and service life under high-current loads.<\/li>\n
  • Conception structurelle :<\/strong> Precision CNC machined to ensure a tight, secure fit with tulip contacts and circuit breaker mechanisms, guaranteeing stable current flow and minimal contact resistance across 2500A to 3150A rated loads.<\/li>\n
  • Sc\u00e9narios d'application :<\/strong> Enti\u00e8rement compatible avec les disjoncteurs \u00e0 vide et les appareillages de commutation de 2500A-3150A, id\u00e9al pour les applications de transmission d'\u00e9nergie, de distribution d'\u00e9nergie industrielle et de centrales \u00e9lectriques. Des dimensions personnalis\u00e9es sont disponibles pour correspondre aux principales marques mondiales de disjoncteurs.<\/li>\n
  • Qualit\u00e9 et approvisionnement :<\/strong> Fabriqu\u00e9s en Chine avec des tests rigoureux de performance \u00e9lectrique et de dur\u00e9e de vie m\u00e9canique. Nous fournissons des services efficaces d'approvisionnement en vrac et de livraison en Asie, en Europe, au Moyen-Orient et dans d'autres r\u00e9gions, conform\u00e9ment aux normes internationales IEC et GB.<\/li>\n<\/ul>\n
