Factors Affecting Terminal Crimp Performance (Part 2)

1. The material of the conductor

With the same wire diameter, the current-carrying capacity of the copper wire is larger than that of the aluminum wire, but the weight of the copper wire is also relatively large. Generally, the conductor is bare copper or bare aluminum, but there may be a coating on the outside of the conductor as required. The common coating materials are tin and silver. In a sulfur-containing environment, the coating of the wire should be tinned. In the case of high requirements on the contact resistance of the wire, silver plating can be used to reduce the contact resistance.

2. Insulation material

The higher the electrical resistance and resistivity of the insulation, the better. In the case of high frequency and high voltage, insulating materials with small dielectric loss tangent should be used.

3. Conductor current carrying capacity

The selection of conductors is often based on the current carrying capacity of the target. When selecting a wire, the current carrying capacity of the wire is usually the first factor.
