JINPAT has the ability to deliver 6600VAC high-voltage slip rings on a large scale

In the product series of JINPAT, the highcurrent slip ring is a very important category. The product code of this seriesis LPA, which is a complete series of carbon brush friction pairs. The vastmajority of products are designed with an empty frame structure, which enablesthem to transmit large power and have the characteristic of long service life.The LPA series is mainly used in heavy-duty electromechanical equipment.Depending on the terminal industry and usage, the high-power slip ringsrequired vary greatly in terms of electrical, mechanical, and protectiveperformance.

Among all the high current slip rings of JINPAT,there are also many products with a working voltage exceeding 5000VAC. Theseproducts are mostly used in equipment such as heavy-duty shore cranes, specialmarine winches, thrusters, and deep water detection robot mother ship controlcenters. These high voltage products have a maximum working voltage of 6600VAC,and their model number is LPA000-03480-01PE-0615-FO06, which is composed ofhigh-power modules, signal modules, and fiber optic slip ring modules, Thefiber optic slip ring of this product is also self-developed by JINPAT. Unlikeother high current products, this slip ring starts to be delivered to customersin bulk once it is finalized.

This type of slip ring has a single currenttransmission capacity of 480A. Due to its high working voltage of 600VAC, ithas the ability to transmit 3MW power. The advantage of ultra-high voltage isthat it can make the volume of this type of slip ring very small, therebysaving product costs and reducing product weight. JINPAT has developed a slipring for power thrusters with a working voltage of 690VAC and a transmissionpower of 3MW. Due to the low voltage, This results in a single circuit currentof up to 4000A, which requires the use of copper rings with extremely largevolume and height. This characteristic leads to a very high overall price andweight of the slip ring.

LPA000-03480-01PE-0615-FO06 is a slip ringdeveloped for shore electric winches, and the working voltage of 6600VAC isalso one of the commonly used voltages for marine thrusters. JINPAT hasextensive experience in designing high-power carbon brush type slip rings withhigh protection levels and anti vibration and impact structures. Therefore,with its strong technical strength, it is also very reasonable to develop sliprings for ultra-high power pod type electric thrusters with working voltages of6600VAC or even 10000VAC above 10-20MW. For example,LPA000-03480-01PE-0615-FO06, this product, by removing the fiber slip ringmodule and strengthening the design of the slip ring structure to meet therequirements of resistance to shipborne vibration and impact, can transforminto a 3MW high-voltage pod type electric propulsion slip ring.
