2500A-3150A Copper Conductive Arm for Vacuum Circuit Breaker
Product Details
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.
- Material & Surface Treatment: 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.
- Structural Design: 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.
- Application Scenarios: Fully compatible with 2500A-3150A rated vacuum circuit breakers and switchgear, ideal for power transmission, industrial power distribution, and power station applications. Custom dimensions are available to match major global circuit breaker brands.
- Quality & Supply: Manufactured in China with rigorous electrical performance and mechanical life testing. We provide efficient bulk supply and delivery services to Asia, Europe, the Middle East, and other regions, adhering to international IEC and GB standards.
