Key Advantages
High Conductivity – Made of Cu-ETP oxygen-free copper (≥99.95%), extremely low electrical resistance.
Excellent Flexibility – Braided structure absorbs vibration and movement, ideal for dynamic connections.
Robust Ends – Welded + hot-dip tinned ends provide low contact resistance and corrosion resistance.
Highly Customizable – Cross section, hole pitch, hole diameter, single wire diameter, end type.
Operating Conditions
• Temperature range: -40°C to +200°C (depends on plating)
• Suitable for indoor & protected outdoor use
• 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, or broken braid strands.
After-Sales Service
Free technical support: engineering consultation, drawings...
Custom orders: lead time & quality report provided before shipment

Frequently Asked Questions
They are made of high-purity annealed Cu-ETP wires (C11000) with a copper content of ≥ 99.95%, offering bare or tin-plated finishes for superior electrical performance.
The connectors are rated for temperatures ranging from -40°C to +200°C (depending on the surface plating selected), making them ideal for high-vibration and dynamic electrical environments.
Yes, full customization is available. Cross-sectional areas range from 1.5mm2 to 500mm2, and length, hole pitch, hole diameter, single wire diameter, and end types can all be tailored to your specifications.
Welded and hot-dip tinned ends ensure exceptionally low contact resistance, excellent mechanical integrity, and high resistance to corrosion and environmental degradation.
Under normal conditions, the expected service life is over 20 years. Maintenance only requires periodic visual checks for damage or corrosion, and routine cleaning with dry air or a soft brush.
Please specify the cross-sectional area, length between holes (L), hole diameter (d), single wire diameter (default is 0.15 mm), and your preferred end configuration.
