From the Perspective of Marine Electrical Systems

1. Core Importance

1. Excellent electrical conductivity
    
   Copper has conductivity close to silver, reducing contact resistance and heat generation, ensuring stable operation of propulsion motors, deck machinery, and power distribution systems.
2. Salt spray resistance and electrical fault prevention
    
   Marine salt spray easily causes oxidation, overheating, and short circuits. Copper and its alloys maintain reliable electrical connections over the long term.
3. Stability under strong vibration
    
   Vibration can loosen or spark ordinary connectors. The mechanical strength and fatigue resistance of copper fittings are critical to electrical safety.

2. Optimum Processing Technology for Electrical Systems

• Material: Oxygen-free copper / high-purity brass
   
  Ensures low resistance, high conductivity, and low heat generation.
• Machining: High-precision CNC turning / milling
   
  Ensures flat contact surfaces and sufficient bonding area to minimize contact resistance.
• Connection technology: Crimping / argon arc welding (GTAW)
   
  Crimping: No virtual connection, low heat, suitable for cable lugs.
   
  Argon arc welding: High strength and consistent conductivity for busbars and high-current connections.
• Surface treatment: Tin plating / nickel plating
   
  Improves oxidation and salt spray resistance and reduces long-term temperature rise.
• Testing: Contact resistance test + salt spray test
   
  Ensures compliance with IEC 60092 marine electrical standards.
