Tin plated copper busbar for transformer high voltage busbar connectors
| busbar power connectors |
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: 57
Tensile strength: 379
