Medium-voltage Slip Rings: at the heart of next-generation industrial electrification

For many industrial machines, ensuring continuous transmission of power and signals during rotation is a critical requirement. However, meeting this requirement becomes increasingly complex as systems evolve. Everaxis medium voltage slip rings address this challenge by combining robustness, modularity, and customization, thereby supporting the most demanding mechanical and electrical architectures.

For several years, Everaxis has been designing and manufacturing custom slip rings capable of handling voltage ranges from very low levels up to 52 kV and currents exceeding 500 A. As a result, these high-performance solutions now play a central role in the most critical electrified systems, on land, at sea, and in the air.

Growing industrial challenges, tailored solutions

Medium and high-power applications come with unique challenges. For instance, they often involve:

• compact & modularized design
• corrosive or explosive environments,
• intense vibrations,
• extreme climates, immersion, and high pressure,
• simultaneous transmission of power and data.

To address these issues, Everaxis develops fully customized, modular slip rings configured to integrate:

• high-voltage / high-current circuits,
• signal channels using various technologies – including optical FORJ, contactless transmission, and contact wired solutions, ensuring high-speed data transfer with strong resistance to electromagnetic interference.
• advanced communication protocols such as Ethernet or CAN bus.

In addition, some solutions comply with strict standards such as REACH, DNV & ATEX, which are essential for hazardous environments and safety-critical operations.

Engineering built to last

Everaxis slip rings are engineered to deliver exceptional endurance, even in the harshest operating conditions. Indeed, each component is carefully designed to maximize long-term reliability.

Their key features include:

• corrosion-resistant housing,
• protection up to IP67,
• option to integrate a plug-in bushing compliant with EN 50180,
• through-bore design up to 500 mm, allowing fluid transfer,
• optional integration of high-speed optical technologies,
• open, partially enclosed, or fully enclosed configurations depending on customer needs.

Consequently, customers benefit from optimized uptime, improved efficiency, and consistent operational performance.

Everaxis solutions are used across numerous strategic sectors. Moreover, their versatility enables seamless integration into both standard and highly specialized systems.

Construction equipment

• hydraulic excavators, wheeled excavators, telehandlers, and material-handling equipment
• tunneling and mining

Many others

• energies with floating offshore wind turbines
• water treatment systems,
• amusement rides, where continuous rotation requires secure transmission of power and data.

In these cases, slip rings play an essential role in ensuring safe and reliable operation.

The Everaxis advantage: performance, expertise, and full customization

What sets Everaxis apart is not only the high performance of its solutions but also their adaptability. Each slip ring is designed to integrate seamlessly into the customer’s system — even when dealing with extreme space constraints, complex architectures, or highly demanding operating conditions.
To guarantee reliable data transmission in environments where conventional technologies reach their limits, Everaxis can incorporate optical FORJ modules as well as contactless signal-transfer technologies directly into its designs. These options provide stable, high-speed communication even in harsh conditions.
