A Comprehensive Guide to Jointing Busbars: Which Method is Best?

May 8, 2023

There are many situations where it is necessary to join two busbars to create a single, unified unit. This process, called “jointing,” may be needed to create a longer busbar from shorter, more manageable pieces; or to create a T-shaped tap-off connection from the main busbar. The result of jointing must simultaneously meet multiple objectives…. View Article

Laminated Bus Bars:

Design, Fabrication, and Testing Expertise Are Keys to Performance, Reliability Laminated bus bars address two power-related design challenges: they significantly reduce voltage drop due to IR loss in high-current power-distribution systems, and their very low stray inductance minimizes a possible cause of instability and output oscillation in switching power supplies.  Depending on size and thickness,… View Article

Engineering Blasphemy: Smaller is not Always Better

USING ALUMINUM FOR BUS BARS   Design engineers strive to make equipment smaller and more efficient.  The hidden assumption being that smaller is always better. Copper bus bars require less cross-sectional area than aluminum and can fit inside a tighter footprint.  Thus, the vast majority of electrical equipment is designed with copper bus bars. However,… View Article
