Advantages

Effective Vibration Damping

Reduces self-vibration and impact during momentary energization, keeping connections tight and preventing loosening compared to rigid conductors.

Efficient Current Conduction

Lower skin effect losses and faster response for optimal electrical performance.

Installation in Confined Spaces

Flexible structure eliminates cumulative tolerances, enabling easy installation in irregular or cramped areas.

Balanced Heat Dissipation

Avoids localized temperature rise caused by molecular lattice damage during cold bending of copper bars.

Operating, Maintenance & Service Life

Operating Temperature Range: -40°C to +200°C (with plating).

Expected Service Life: 10–15 years under normal dry indoor conditions.

Maintenance & Inspection: Bare copper in humid environments requires inspection every 6–12 months. Plated versions require minimal care. Check terminal tightness annually in high-vibration applications.

Applications & Market Leadership

Industry Applications: Widely used in power electrical equipment, new energy “solar-storage-charging” (PV + ESS + EV charging), new energy vehicle drives, and wind power generation.

Global Market Presence: Ranked #1 in both China and global market share for copper braided wire for 10 consecutive years (2015–present).
