Description

Product Details

Laminated copper flexible shunt is a core conductive component specially developed for resistance‑welding equipment. It is manufactured by stacking multiple thin high‑purity copper foils, with both terminals hot‑pressure welded into integrated solid terminals. It serves as flexible busbar between welding transformer and welding arm of spot‑welding machines.

The flexible multi‑layer structure compensates mechanical displacement and absorbs vibration generated during continuous welding cycles, realizing stable heavy‑current transmission. Both standard parts and full‑customized solutions according to customer drawings are supported.

Core Features

1. Adopt high‑purity T2 copper foil raw material, excellent electrical conductivity and low power loss.
2. Multi‑layer laminated flexible structure, offsets position deviation and dampens vibration.
3. Terminals with hot‑pressure welding process, high bonding strength, no layer separation.
4. Good heat dissipation performance, effectively reduces temperature rise under long‑term high‑current working condition.
5. Optional surface finish: bare copper or tin‑plating for anti‑oxidation.
6. Fully customizable: length, width, foil layers, mounting hole dimension and shape can be adjusted as per requirements.
7. High fatigue strength, stable performance for continuous welding working scenarios.
