JINPAT Delivers Reliable Power Transmission Solutions for Shore Power Winches

In the field of marine engineering, shore power winches serve as critical equipment for deep-sea energy transmission and device deployment, demanding exceptional reliability, pressure resistance, and environmental adaptability from power transmission systems. Leveraging nearly three decades of slip ring R&D expertise, JINPAT has developed the LPA000 series of high-current slip rings specifically for shore power winches. With industry-leading capabilities including 6,600 VAC ultra-high voltage transmission, 480A single-circuit current capacity, and temperature rise fluctuations below 1°C, this series has become a technological benchmark in the sector.

The LPA000 series enables stable 3MW-level power output to meet the extreme energy demands of deep-sea cable winches. Its carbon-brush friction pair design and open-frame heat dissipation structure maintain contact resistance below 0.1Ω even under 35kA short-circuit current impacts, reducing energy loss to industry-leading levels and serving as a secure, efficient power hub for port shore power systems.  

In extreme environments such as deep-sea high pressure and salt spray corrosion, traditional slip rings are prone to failures caused by uncontrolled temperature rise or material aging. The JINPAT LPA000 series addresses these challenges through three major technological breakthroughs. First, its open-frame heat dissipation design maintains contact point temperature fluctuations below 1°C after 2 hours of full-load operation, far exceeding industry standards. Second, IP56 protection rating combined with salt spray-resistant stainless steel. Third, the integrated 6-channel fiber optic signal transmission module enables synchronous, lossless interaction of power and data, facilitating intelligent winch control.

With the acceleration of global port greening transformation, shore power systems - serving as core equipment to replace fuel-powered generators during vessel berthing - see their stability and safety directly influenced by slip ring technical performance. JINPAT LPA000 series slip rings, leveraging their breakthrough high-voltage and high-current carrying capacity coupled with exceptional stability, deliver premium slip ring solutions for global port shore power winch systems.
