The Role of Slip Rings in Subsea Plough Systems

Penlink's slip rings redefine the possibilities of subsea power and data transmission, conquering the challenges within the offshore industry. Our solutions not only offer reliability but are also cost-effective, eliminating downtime. With our slip rings, you can seamlessly transfer power, data, and signals through a full 360-degree rotation without any risk of tear or damage.

FIBER OPTICAL COMPATIBILITY
Seamlessly integrating both multi-mode and single-mode fiber optical rotary joints into our solutions, we offer a versatile range of contacts such as ST, SC, LC, and FC, accommodating 1 up to 24 channels.

Integrating fiber optics enhances data transmission capabilities, precisely catering to the unique requirements of offshore winches in the subsea industry.

VERSATILE POWER AND DATA CONNECTIVITY
Our slip rings are designed to support various data bus systems, including Profinet, Profibus, Ethercat, and 1GB Ethernet.

This comprehensive compatibility allows for seamless integration into diverse communication networks, providing flexibility and adaptability tailored to the specific needs of deep-sea operations.

HIGH-VOLTAGE OR HIGH-AMPERAGE
Our solutions for efficient power delivery are offered in two distinct approaches to precisely meet your requirements. The seamless transmission they provide is particularly well-suited for deep winch operations, especially during activities like plowing to lay down cables in the ocean.

Regardless of your choice, both solutions ensure the reliable transmission of power, signals, and data vital for running your operation. The key considerations come down to your specific voltage and amperage needs, as well as spatial constraints.

The high-voltage solution, contrary to its name, is more compact, offering a space-efficient design. On the other hand, the high-amperage solution is engineered for robust performance, making it ideal for applications demanding higher power intensity.

HIGH-VOLTAGE SLIP RING SOLUTION
The high-voltage slip ring, with its robust 4500V and 40A power transmission, is pivotal in subsea cable plough operations. Equipped with fiber optics for signals and internal heaters for reliability, this solution serves as the cornerstone, ensuring uninterrupted power to the winch motor.

It enhances operational precision by facilitating real-time signal transmission for depth control and cable laying. In challenging subsea conditions, internal heaters prevent condensation, making the high-voltage slip ring an essential component for efficient and precise subsea cable plough operations.

HIGH-AMPERAGE SLIP RING SOLUTION
The high-amperage slip ring solution is purpose-built for applications demanding robust amperage, transmitting 690 volts and 260 amperes. We offer fiber optic slip ring integration for signal transmission and internal heaters to control condensation within the unit.

With a higher kilowatt transmission, larger cables are necessary, but we keep them efficiently compact with 2x70 square millimeters of cross-sectional area. This design ensures effective heat management during high-amperage transmission.
