Advantages
Effective vibration damping: Flexible multi-strand structure reduces self-vibration and impact during momentary energization; connections stay tight.
Efficient current conduction: Annealed Cu-ETP (≥99.95%) minimizes skin effect losses and ensures fast response.
Suitable for complex bending motion: Withstands repeated bending without fatigue failure.
Large bending radius yet compact structure: Smaller bending radius than copper bars for the same cross-section, enabling flexible installation.
Installation in confined spaces: Flexible design eliminates cumulative tolerances, easy routing in irregular or cramped areas.
Balanced heat dissipation: Avoids localized temperature rise caused by molecular lattice damage when cold-bending copper bars.
Operating & Maintenance
Temperature range:
–40°C to +200°C (tin-plated)
Service life:
10-15 years under normal dry indoor conditions.
Inspection:
Bare copper in humid environments-inspect every 6-12 months; tin-plated version requires minimal care.
Packing:
rolls, spools or wooden drums.
Check terminal tightness annually in high-vibration applications.
Compliant with GB/T12970.2-2009, cross-sectional area 1.5-2000 mm².
Applications
Used for flexible conduction and grounding connections in electrical installations, switchgear, electric furnaces, storage batteries, etc. Widely applied in new energy “solar-storage-charging”, new energy vehicle drives, wind power generation, and more.
