High current slip ring is applied in military field. It had to consider two elements: the contact material and installation performance.

Nowadays, more and more machinery equipment uses the conductive slip ring. As the conductive slip ring can help mechanical equipment to improve the performance of wire transmission which so improves the operation efficiency of mechanical equipment. But the parameters of each machinery is different, such as working environment, current, voltage, protection grade, working speed and so on, so that promote the development of all kinds of slip ring models. For example, large current conductive slip ring is often used in communication equipment and instruments. In the case, when rotating, transmission wire does not damage due to twisting. By slip rings, it can ensure the smooth of electrical connection. So how do we design large current conductive slip ring?

As it is high current device, the primary consideration is the contact material and brush contact, installation way to ensure the slip ring reliability and service life of the high current conductive ring under the working state. Then the installation performance of slip ring can make sure the normal installation of the device. As high current slip ring will be used in seas, it’s very essential to use corrosion resistant stainless steel. The main parts of slip ring are body and brush and its surface electrical material adopts plated thick gold. It produces high current density and minimum wear, but has large resistance. According to above points, a certain number of brushes can be the final brush. In machinery structure, the feature of high current should be taken into consideration.

Advantage

a. Use imported graphite alloy

b. Current up to several hundred amperes

c. Compatible with data protocols

d. Ultra-long life, free maintenance, no lubrication

e. 360 degree continuous power or data signal

Large current conductive slip ring has a unique contact and connection way. It has the advantage of good electrical contact performance, long service life, flexible structure, comprehensive performance. So large current slip ring can reach the level of similar foreign products.
