Wind
Welcome to the future of renewable energy! Kraus has been a pioneer in the field of slip ring transmitters for wind turbines since the 1960s. With our robust products we stand for quality and durability.
The future belongs to renewable energy, and with it, the demand for solutions and unique products which enhance their utilization is growing.
Kraus’s first slip ring transmitters were specifically developed and designed for wind turbines in the early 1960s. And to this day they continue to impress with outstanding quality parameters thanks to decades of experience in every aspect.
In addition to stable transmission quality during continuous rotation, the robustness of our products is of great importance. Our slip ring transmitters are low-maintenance and can withstand up to 150 million revolutions in wind turbines. Furthermore, we offer construction variants that ensure resistance to seawater for offshore applications. Thanks to their modular design, our slip rings are not only flexible in structure and adaptable to various requirements but also allow for the most cost-efficient planning. The patented plug-in technology enables easy assembly and disassembly, including a plug & play option.
Offshore
In hazardous industrial environments, reliable electrical connections are crucial. Kraus’s explosion-proof slip rings provide high safety and performance, especially in offshore installations for oil and gas production.
In industrial environments where hazards are ever-present, the reliability of electrical connections is of utmost importance. Explosion-proof slip ring assemblies are designed to ensure the highest safety and uninterrupted performance in the most demanding conditions.
Especially in the field of offshore installations for oil and gas production, as a producer of slip rings, we carry a significant responsibility and ensure that all our devices comply with specified safety standards. Explosion protection is a crucial and essential requirement in this context.
Kraus’s slip rings not only transmit the required power but also ensure reliable transmission of control signals. Power ranges, materials used, and design can be optimized to meet individual customer requirements. Kraus Elektrotechnik is known for the high durability and technical quality of its products applicable on oil drilling platforms and other offshore installations. Here, they work reliably and safely to meet the demanding requirements of oil and gas production.

Safety
The slip ring plays a crucial role in the seamless transmission of data, signals, power, or media between rotating and static components. We provide customized solutions for effective, secure, and reliable applications in defence technology.
The field of safety and defence technology places high demands on products concerning general quality standards, reliability, and flexibility. It is one of the most challenging industry segments.
The high sensitivity to quality has good reasons: In case of emergency, security systems depend on the flawless operation of their individual components. Therefore, each component must reliably perform its specific function. We understand the specific requirements of these sensitive application areas and deliver slip ring solutions that meet the highest safety standards.
We design and manufacture slip ring applications in defence technology, ensuring the highest security and readiness even under extreme environmental and climate conditions. Through a clearly structured design established based on customer specifications, our slip ring transmitters are precisely tailored in function and construction to meet your individual requirements, allowing for efficient operation.
In defence technology, the slip ring is an example of advanced technology that contributes to enhancing military effectiveness and ensuring the safety of various applications. Their ability to seamlessly transmit data, power, and various media between rotating and stationary components makes them an essential element in a variety of critical applications.
Explosion proof applications
In explosive environments, a single spark or elevated ambient temperatures poses a potential danger. The use of slip rings in such environments requires specific safety precautions.
Explosion-proof slip ring transmitters are the foundation of safety in industries where explosive atmospheres are of constant concern. Environments with an elevated risk of explosions are particularly found in areas where flammable gases and dust are present. These slip rings are designed to prevent or extinguish electrical sparks or arcs before they reach the easily ignitable atmospheres outside the slip ring, making them a critical component in industries such as the oil and gas sector, chemical production, mining, agriculture, and more.
The robust construction of slip ring transmitters, their certified safety features, and customization options make them an indispensable component for protecting personnel, equipment, and the environment.
For 20 years Kraus Elektrotechnik has been developing and manufacturing explosion-proof slip ring transmitters, which are approved according to the following standards and certifications:
