Key Parameters for Selection
1.Conductor Material
●Copper (Cu): High conductivity, ideal for high-current applications (e.g., power distribution systems).
●Aluminum (Al): Lightweight and cost-effective, but avoid direct contact with copper (use transition terminals).
2.Crimping Requirements
●Verify compatibility with mixed copper/aluminum conductors or multi-strand wire connections.
3.Environmental Adaptability
●High-temperature environments (>85°C): Choose heat-resistant materials (e.g., tin-plated copper).
●Vibration-prone scenarios: Prefer terminals with good elasticity (e.g., aluminum alloys).

Important Notes
1.Matching Principles
●Ensure the cross-sectional area is ≥ the cable’s actual current-carrying capacity (refer to IEC 60364).
●Control cable diameter deviation within ±5% to avoid loose crimps.
2.Installation Standards
●Perform a tensile test after crimping (standard value: 70%~80% of the conductor’s tensile strength).
●Replace terminals or apply protective coatings if the insulation sleeve is damaged.
