Marine equipment is used to exploring ocean resources and improving deep-sea mining, ocean power generation industries.   Slip rings, as the imperative parts of the equipment, are applied widely to a crane, shipborne radar, winch, precise marine propeller system and so on.

    JINPAT, designed and manufactured the LPA series, which are perfectly suitable to the marine field. By effectively integrating photoelectric/high-frequency and electricity, the slip ring comes with automatic heat abstractor and heating devices. A carbon brush in power ring is made from advanced graphite alloy, which allows minimal electrical noise and stable connection. Special sealing design and surface processing technique make the electrical connector mist, corrosion, and acid-proof and vibration, shock resistant. Convenient for use and maintenance, the electrical slip ring contains a functional structure, which allows a high current capacity with a stable signal transmission. Although the crane and marine propeller system, being large-scale machinery, provide challenges for the electrical connectors, JINPAT slip ring, with a large-current transmission (up to 1500A) and persistent durability, offers a smooth long-time operation for the heavy equipment. Moreover, JINPAT marine slip ring has an outstanding performance in a temperature of -55℃+120℃ with minimal electrical noise and transmission loss. In addition, it can be designed with a through a hole up to φ900mm. Overall, its excellent quality guarantees a reliable transmission for the winch and shipborne radar.
