Flexible laminated copper busbar for high voltage switch
Product Description
high voltage busbar
Pressure welding soft connector
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.
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, see the scheme (I) shown in the figure.
When A is greater than 140mm and B is greater than 130mm: Brazing process is used, see the scheme (II) shown in the figure.
Technical parameters
See the table below.
The width, length and drilling holes not included in the table below can be processed according to user requirements.
The allowable current carrying capacity is a reference value. This value is related to the installation and use conditions of the soft connector.
