Laminated Bus Bar

The laminated busbar is applied to connect the power devices of the electrical and electronic product It is a multilayer conductor and insulator composite structure products This laminated Busbar could be customized or specified according to your design or drawing Clients can also provide information of real application information for us and we can design products on the basis of such information

Products Profile

Space Efficient	Compared to the power electronic devices connected through wiring, it significant save at least 50% of the space.
Easy to assemble	Busbar combination the electronic system into a organic integnity, via different signs make the assembling easy and convenient for maintenance. Acoording to these it reduce the cost of the manufacturing and on-site maintenance.
Enhance Electrical Properties	The high capacitance distribution produces low characteristic impedance, while the larger surface area and cross-sectional area realize the design of low inductance
Improve current carrying capacity	Larger cross-sectional area to achieve high current load, wide and short design with low pressure drop.
Better thermal performance	The larger surface area allows for better thermal absorption, thermal dissipation, and thermal radiation.
Long-term reliability	BUSBAR organic reasonable design, easy to use, assemble, make electrical and mechanical performance not easy to fail.
