A high current slip ring is often used in communication devices and equipment.

is often used in communication equipment and other equipment to avoid the system in operation. And to ensure a smooth electrical connection, transmission cable will not be broken due to twisting through the use of a conductive slip ring. So how do we design a high current conductive slip ring?


The BC050 provides 3~6 Circuits 400V 300A , and 2 ~ 24 control signal .The Slip ring assebies use carbon conduction , IP66 protection is optional .
