Flexible Copper Laminated Busbar For Transformer
The pressure welding is to press the copper foil laminations together, using molecular diffusion welding, and forming by high-current heating and pressure welding.
Copper foil: 0.03mm to 0.3mm thick.
The contact surface can be tinned or silver plated according to users’ requirements.
Copper content: 99.98%
Electrical conductivity: 57a
Tensile strength: 379N
Description of pressure welding / brazing
In order to ensure the flatness of the contact surface,
■When A is greater than 90mm and B is greater than 60mm; use the contact surface paste copper friend (1mm thick) pressure welding process。
■When A is greater than 140mm and B is greater than 130mm: Brazing process is used.
