Frequently Asked Questions (FAQ)
1. What material is used for the flexible copper connectors?
Our connectors are manufactured using high-purity annealed Cu-ETP wires (C11000) with a copper content of ≥ 99.95%, ensuring exceptional electrical conductivity and low resistance.
2. What surface treatment and finish options are available?
We offer both bare copper and hot-dip tin plating. The tinned finish offers superior anti-oxidation and corrosion resistance in humid or demanding environments.
3. What is the standard operating temperature range?
The connectors operate safely within a temperature range of -40°C to +200°C (depending on the surface plating chosen), suitable for dynamic industrial and high-vibration applications.
4. What parameters are needed to place a custom order?
Please specify cross-sectional area (1.5mm² - 500mm²), length between holes (L), hole diameter (d), single wire diameter (default 0.15mm), and end type requirements.
5. What is the expected service life and when should they be replaced?
The expected service life exceeds 20 years under normal operating conditions. Replacement is recommended if you notice ferrule cracking, overheating discoloration, or broken braid strands.
6. Do you provide engineering consultation and customized drawings?
Yes, Zhejiang Bridgold Copper Tech Co., Ltd. provides free technical engineering consultations, CAD drawings, and complete quality inspection reports prior to shipment.
