Technical Requirements For Piercing Wire Clamps Under Conductivity

piercing wire connector During operation, it needs to withstand a continuous current load, making conductivity the primary indicator for evaluating its quality. While tin's conductivity is lower than pure copper, its oxides are far superior. When the piercing teeth penetrate the insulation and contact the conductor core, the tin-plated surface forms a stable conductive channel at the contact interface. Even after prolonged use and slight oxidation, it maintains a low contact resistance.

Copper is prone to oxidation in air, and the resulting verdigris significantly reduces conductivity. In contrast, the tin layer forms a dense protective film on the metal surface, preventing direct contact between oxygen and the substrate, thus maintaining the electrical stability of wire piercing connector in outdoor or humid environments.
