Electrical Design of Laminated Busbars
The electrical performance of a laminated busbar is determined by three fundamental properties: resistance, inductance, and capacitance. As performance requirements for electronic equipment and components become increasingly stringent, these properties gain greater importance; minimizing resistive losses and electromagnetic noise in power distribution systems has become a primary objective for designers.
A laminated busbar, thanks to its structure based on parallel conductive plates separated by insulating materials, provides significantly lower inductance values compared to cable harnesses. While a cable with the same size and current-carrying capacity may have an inductance of 250nH, a laminated busbar can reduce this value to as low as 25nH. Low inductance means lower characteristic impedance and more effective noise suppression. Additionally, copper or aluminium plates with large surface areas ensure uniform thermal distribution, thereby reducing power losses.
Laminated busbars can be manufactured with various types and structures of insulation layers. E-LAM is designed with different insulation alternatives capable of withstanding high temperature and pollution levels. It eliminates dielectric issues through partial discharge control. In this way, the system ensures stable power transmission at consistent values over many years of operation.
