Environmental Performance Of Copper Terminal Blocks In Humid Environments

copper terminal block will face unique physical and chemical effects when exposed to environments with high water content. When the metal surface of copper distribution block comes into contact with moisture in the air, an oxide layer or corrosion products may form in a short period of time. Over time, these changes will affect the electrical properties of the contact surface. Metals are more prone to surface changes and oxidation under high humidity conditions.

When air humidity rises, dissolved pollutants carried on the system may accumulate in tiny gaps, forming a medium for electrochemical reactions. This can alter the contact resistance and surface structure inside the copper terminal strip, and long-term accumulation can affect the overall system performance.
