Best Practices for Busbar Edge Conditioning

Proper edge conditioning and sealing is a critical consideration for laminated busbars for a number of reasons, including:

  • Safety: It shields the conductors from FOD (ie. dropped washers that could cause a failure) and is safer for things that could touch the part like people, cables, and nearby components.
  • Environmental: Sealing the edges protects the busbar from environmental factors like moisture, dust, or contamination.
  • Enhancing Electrical Performance: Sealing helps in maintaining the electrical properties of the busbar, while also improving creepage and clearance.
  • Improving Mechanical Strength: Sealing also contributes to the mechanical strength of the busbar assembly, providing additional support and protection against physical damage.

This new Applications Note provides an overview of four methodologies for sealing laminated busbars.

Also, these drilldown pieces provide more detail on each method.
