Product Advantages
Superior corrosion & oxidation resistance: Nickel or silver cover foils protect the copper core without any trapped plating solution.
No re-welding & high weld quality: Molecular diffusion welding on both ends creates a strong, low-resistance joint.
Compact & space-saving: Soft-state forming fits into small installation spaces; various flexible part designs (straight, offset, angled, stepped) match different equipment layouts and movement states (vibration, thermal expansion, misalignment).
Easy installation: The flexible section reduces terminal stress; no special tools required.
Forming (soft-state) position customizable: The exact bending location of the flexible area can be tailored to unique spatial constraints.
Operating Conditions
Temperature range: -40°C to +200°C.
Atmosphere: Suitable for indoor/outdoor use in clean, non-corrosive atmospheres; avoid direct chemical exposure.
Mechanical resistance: Withstands high vibration (EVs, rail transit) and frequent thermal cycling.
Current capacity: Depends on cross-sectional area & ambient temperature, engineering consultation recommended.
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.
After-Sales Service
Free technical support: engineering consultation, drawings...
Custom orders: lead time & quality report provided before shipment

Frequently Asked Questions (FAQ)
What raw materials are used for these flexible connectors?
The base core material is high-conductivity C11000 copper foil (≥99.95% Cu), laminated with nickel or silver cover foils on the upper and lower outer layers.
What is the standard operating temperature range?
The products operate reliably across a broad temperature range of -40°C to +200°C in clean, non-corrosive indoor and outdoor environments.
Can the connector shapes and soft-state bending positions be customized?
Yes, soft-state forming positions are fully customizable. Flexible sections can be designed as straight, offset, angled, or stepped configurations to match specific spatial constraints.
What welding technology is utilized for the terminal connections?
Molecular diffusion welding is applied at both ends to create a seamless, high-strength joint with exceptionally low electrical resistance without secondary re-welding.
What is the expected service life and maintenance requirement?
The estimated service life is over 20 years under normal operating conditions. Routine maintenance requires only periodic visual inspections and cleaning with dry air or a soft brush.
What details are needed to request a custom quote or order?
Please provide overall dimensions (L×W×T), connector shape, hole specifications, foil thickness, surface finish, cross-sectional area or current requirements, along with a 2D PDF/DWG drawing.
