Laminated Busbar

Input AC Reactor

Laminated Busbar

a bus bar consists of one or more flat electrical conductors laminated and electrically insulated by a thin dielectric material which is encapsulated or sealed along the edges. this laminated bus bar could is low lead inductance and saves installation spaces. it is widely applied in power electronics, communication systems, transportation and such field to improve system performance and reduce cost.

Features of Laminated Busbar
1. Low stray inductance
2. Minimal impedance, voltage drop
3. Reduce noise, electromagnetism and radio interference
4. Easy to install and maintain
5. Reduce the amount of devices; improve the integration density and reliability of the system
