JINPAT: A professional manufacturer of low-power electric drive slip rings

With the continuous pursuit of energy efficiency, various types of ships are increasingly adopting electric propulsion systems to reduce energy consumption. In line with this trend, low-power electric propulsion systems are increasingly being applied as the primary propulsion system. In these spooled electric propulsion systems, slip rings are indispensable core components. As a well-known slip ring manufacturer, JINPAT has consistently achieved a leading position in the industry in the research of slip rings for spooled electric propulsion systems. The emergence of electric propulsion technology has brought huge market opportunities to JINPAT.

Compared with small electrical equipment in other industries, even low-power electric propulsion systems used in inland waterway shipping typically start at power ratings of hundreds of kilowatts. These propulsion systems are primarily suitable for small-tonnage basic cargo ships. To meet the needs of these inland waterway ships, JINPAT has developed a specialized series of 200KW slip ring products. This series includes two categories: an ultra-compact type represented by the product LPA000-06200-0618-44S-01A-05L and a standard compact slip ring type with carbon brush represented by the product LPA000-06200-0618-44S-01A-06L. The main functional difference between these two products lies in the number of pneumatic and hydraulic channels.

Among them, LPA000-06200-0618-44S-01A-05L represents a high-protection super-protective slip ring for reinforced propulsion systems. Even without taking the height of the PG connection into account, the overall height of this product is only 1117mm, with the stator body dimensions of 340mm x 320mm. It is worth mentioning that this slip ring is not only small in size but also achieves an IP65 protection rating. In contrast, the protection rating of LPA000-06200-0618-44S-01A-06L is IP54. Despite the low protection rating of this slip ring, JINPA’s engineering design team, backed by their exceptional technical expertise, has successfully overcome this challenge and achieved a comprehensive design that meets the requirements of compactness, multi-channel, high protection and high power transmission.

In addition to processing slip rings for small power propulsion systems, JINPAT has extensive experience in product development in the field of slip rings for propulsion systems with power ratings below 5MW. Currently, JINPAT has successfully developed various models of slip rings with single-channel currents of 1000A, 2000A, and 4000A for customers, with rated voltages of 690V, 1000V, and 3300V, respectively. Similar to the 200kW slip rings, these slip rings are also composed of pneumatic and hydraulic units, super-power units, and ordinary electrical signal units. These three units operate independently and are designed with a high degree of physical isolation to ensure that high currents during operation do not interfere with electrical signals. In conclusion, JINPAT, as a professional slip ring manufacturer, has excellent research and innovation capabilities in the field of slip rings for low-power electric propulsion systems. With the continuous advancement of electric propulsion technology, the company provides high-quality and high-performance slip ring products, contributing to a more efficient and sustainable development of the marine industry.
