High Current Slip Ring

JINPAT's high-current slip ring series is a professional product line designed to meet the demands of high-power, high-voltage, and high-current transmission. The core feature of this series is its powerful power transmission capability, enabling the stable and continuous delivery of thousands of amperes of current and thousands of volts of voltage between stationary and rotating parts of equipment. Therefore, it is also commonly referred to as a high-current slip ring, high-power slip ring, or high-voltage slip ring.

Features:

• Superior Electrical Performance: Utilizes highly conductive materials, optimized contact structure, and heat dissipation design to ensure low resistance, low temperature rise, and stable operation during high-current transmission, meeting long-term heavy-duty requirements.

• Focusing on Heavy Industry: Designed for harsh environments, typical applications include wind turbine generators (transmitting megawatt-level power), port cranes, mining machinery, large testing equipment, and special vehicle platforms.

• High Integration: Supports modular design, allowing integration with hydraulic/pneumatic rotary joints to simultaneously transmit power, signals, fluids, and gases within a single interface, significantly improving system integration.

• Rugged and Customizable: We can provide corresponding protection levels (IP54/IP65, etc.) and customized mechanical structures to suit complex industrial environments, based on actual working conditions (such as dustproof, waterproof, corrosion-resistant, and wide temperature range).

JINPAT Large   Slip Rings are applied in heavy industry like construction machines, offshore platforms and podded ship propeller systems, etc. We have many mature high power solutions like crane slip rings, fire engine slip rings, marine winch slip rings, entertainment equipment slip rings and so on. By far, JINPAT has developed many successful high power rotary transmission solutions for clients at home and abroad. For our excellent slip ring performances and product quality, JINPAT has won lots of returning customer. So feel free to contact us for custom slip ring solutions!
