Braided Busbar – Anti-vibration Cross-connection & Displacement Compensation
Typical Applications: High‑current connections between bogies and car body, inter‑car busbar crossings, pantograph/current collector flexible leads, gearbox grounding.
Advantages: Extreme flexibility absorbs multi‑directional vibration and coupler displacement, preventing rigid fractures; compensates for assembly tolerances, simplifies on‑site installation.
Expertise Support: 40‑year braiding process database, validated by tens of thousands of fatigue tests, ensures stable contact resistance under -40°C~+125°C and severe vibration.
Braided/Standard Wire – Grounding & Auxiliary Circuits
Typical Applications: Car body grounding, bogie grounding, equipotential bonding of equipment enclosures, signal shielding grounding, maintenance jumper leads.
Advantages: Flexible and lightweight, easy to route, ensures reliable grounding and fault current diversion; available in bare copper, tin‑plated, or silver‑plated for various corrosion protection needs.
Expertise Support: 40 years of stranded/braided process accumulation, with strong batch consistency, guarantees long‑term safe operation of rolling stock.
