AgCu Contact Assemblies For Switchgear
Products Description
AgCu Contact Assemblies for Switchgear are critical core components in power switchgear, ensuring reliable conductivity, breaking capacity, and arc resistance. APOLLO has focused on electrical metal solutions since 1990, leveraging its proprietary manufacturing processes and rigorous quality control system to provide customers with high-performance, long-life, and fully internationally compliant AgCu contact assemblies. Our products are widely used in medium and high voltage circuit breakers, load switches, contactors, and various relay protection devices, ensuring the safe and stable operation of power systems.
Product Features and Characteristics
Superior Electrical Performance
Utilizing a high-purity Welded Electrical Contact Parts material ensures extremely low contact resistance and temperature rise, high conductivity, and the ability to withstand large currents and instantaneous overloads.
Excellent Arc Erosion Resistance
The silver layer of the Brazed Silver Contact Assemblies provides excellent resistance to arc burn-off, while the copper substrate offers good mechanical support and heat dissipation, significantly extending contact life.
High Mechanical Strength and Weld Resistance
The unique composite material structure and processing give the Copper Silver Welded Contacts high hardness and impact resistance, effectively preventing weld adhesion under fault currents.
Stable Chemical Properties
Strong surface oxidation resistance ensures stable contact performance even under complex environmental conditions, reducing maintenance requirements.
Metal Forming and Manufacturing Processes
| Silver-Copper Composite Rolling | Silver and copper strips of the Custom Electrical Contact Components are cold-rolled together to form a uniform silver-copper composite substrate, ensuring material composition stability. |
| Welding/Brazing Technology | For components requiring assembly with conductive rods or supports, we use a high-precision Brazed Silver Contact Assemblies process. High-temperature brazing filler metal is used under a protective atmosphere to ensure full, continuous conductivity and strength far exceeding that of mechanical connections. |
| Forming and Machining | Welded Electrical Contact Parts shapes are formed through precision stamping, turning, and milling processes, ensuring dimensional tolerances at the micron level to meet the assembly requirements of various switching devices. |
| Surface Treatment and Strengthening | Polishing, plating reinforcement, and other post-treatments can be performed to further improve corrosion resistance, reduce the coefficient of friction, or enhance specific properties. |
Packaging and Transportation
Packaging Method
Anti-static pallets are used for sealed PE bag packaging. Each bag is categorized by model, and the outer layer is reinforced with a cardboard box. A product list and quality inspection report are included.
Transportation Guarantee
Express delivery and logistics are supported. International orders are shipped by sea/air freight, with full tracking of the logistics status for Copper Silver Welded Contacts.
Protective Measures
A desiccant is included in the packaging to prevent moisture and oxidation of AgCu Contact Assemblies for Switchgear during transportation.
