Key Advantages

Excellent mechanical properties

Compaction creates a solid end - The solderless pressing process compresses the ferrule onto the copper stranded wire without altering its overall dimensions. This creates a dense, solid end that prevents strand loosening, enhances pull-out strength, and ensures reliable termination even under high mechanical stress.

Reduced thermal resistance

The flexible stranded structure combined with ≥99.95% pure copper provides excellent heat dissipation, significantly lowering temperature rise under high current or short-circuit conditions, thus improving system reliability.

Customized terminal machining

Ends can be drilled, milled, machined and profiled to meet mechanical demands: Our terminals are not limited to standard holes. We can drill, mill, profile, or fully machine the pressed or welded ends to create custom slot patterns, threaded holes, or complex mounting shapes, eliminating the need for additional adapters.

Superior vibration & fatigue resistance

The fine multi-wire stranded design absorbs mechanical stress without work hardening, making it ideal for dynamic applications like traction motors or railway connections.

Low and stable contact resistance

Solderless pressed ferrules ensure a large, uniform contact interface that remains stable over thermal cycles.

Operating Conditions

Temperature Range

-40°C to +200°C (depends on plating)

Environment

Suitable for indoor & protected outdoor use

Application Suitability

Excellent for high-vibration & dynamic applications

Maintenance & Service Life

Maintenance

Periodic visual check for damage/corrosion; clean with dry air or soft brush.

Service Life

>20 years under normal conditions. Frequent flexing reduces life.

Replace if ferrule cracks, overheating discoloration occurs, or broken braid strands are present.

After-Sales Service

Free Technical Support

Engineering consultation, customized design, and detailed technical drawings.

Custom Orders

Precise lead time tracking & comprehensive quality inspection reports provided before shipment.

Ordering Checklist
