In the realm of modern heavy industry, the stable and safe transmission of hundreds of amperes of current from a stationary power source to equipment undergoing 360° rotation has long stood as a core technical challenge. To address this, JINPAT Electronics has introduced the LPA series of high-current slip rings, offering a robust solution for the port machinery, marine engineering, and heavy lifting industries.
Core Advantages: Robust Current-Carrying Capacity and Extreme Protection
Based on the technical specifications of the LPA series, the product demonstrates four key capabilities when operating in complex environments:
Ultra-High Current Capacity with Minimal Temperature Rise: Supports the simultaneous transmission of multiple high-current circuits—rated at 250A and above—with voltages reaching up to 750V DC. Through optimized contact materials and structural design, the series ensures extremely low contact resistance even under heavy-load conditions, thereby effectively suppressing heat generation.
IP67 Deep-Sea Grade Protection: The series features exceptional sealing performance; even in extreme environments involving heavy rain, pounding waves, or brief submersion, its internal electrical systems remain absolutely dry, thereby ensuring operational safety.
Military-Grade Reliability: Utilizing high-strength alloy housings and precision metal contacts, the product not only minimizes signal loss but also possesses superior resistance to vibration and shock, significantly extending the equipment's maintenance-free operating cycles.
-
Integrated Transmission Capabilities: While simultaneously transmitting high-power electricity, the series can seamlessly integrate high-speed Ethernet, control signals, and fiber optic channels, perfectly meeting the data feedback requirements of industrial automation systems.
Typical Application Fields
In Rubber-Tyred Gantry (RTG) cranes and Rail-Mounted Gantry (RMG) cranes, JINPAT slip rings provide an uninterrupted power supply to the rotating crane turrets and high-power electromagnetic lifters, thereby ensuring the continuity and efficiency of container handling operations.

Benefiting from high-grade anti-corrosion enclosures and advanced sealing technologies, this product series is widely deployed in deep-sea winches, offshore drilling platforms, and Remotely Operated Vehicles (ROVs), demonstrating robust performance in harsh marine environments characterized by intense salt spray.
During the tunneling operations of shield machines, high-current slip rings must not only withstand severe mechanical vibrations but also continuously transmit electrical power within underground environments characterized by high temperatures and heavy dust. JINPAT products have successfully passed these rigorous tests, demonstrating an exceptionally low failure rate.
From deep-sea operations to automated ports, JINPAT Electronics remains dedicated to utilizing its sophisticated power transmission technology to connect every rotating power hub within heavy machinery across the globe.
