A Mismatch Between The Conductor Cross-sectional Area And The Size Of The Bimetallic Terminal Will Reduce The Strength Of The Contact.

The bimetal terminal lug is designed to connect conductors of different materials, while the bimetallic lugs price in different sizes is matched with wires of different cross-sectional areas. If the selected bimetallic lugs price list cross-sectional area does not match the wire cross-sectional area, gaps or misalignment will occur at the contact surface, reducing the contact area between metals during mechanical crimping and resulting in insufficient mechanical gripping force at the connection point.

When the wire cross-sectional area is smaller than the preset internal size of the terminal, the wire cannot fully fill the terminal cavity, reducing contact pressure, and the force applied by the bolt or crimping tool cannot be evenly distributed across the entire contact surface. In this state, the contact is weak and prone to loosening under vibration or thermal cycling conditions, resulting in increased local resistance and temperature rise. A similar situation occurs when the cable lug bimetal is too large and the conductor is too thin, the internal gaps reduce the overall structure's vibration resistance.
