Wind power

Whenever power and signals have to be transmitted from stationary to rotating facilities e.g. power to the pitch drive of the blades, the transmission of all bus systems (Profibus, Fast Ethernet 100 Base Tx a. o.) and signals from the generator head to the rotor and vice versa, SCHLEIFRING systems are the answer.
Standard lifetime for proven gold wire technology designs: 50 million revolutions  

Design options

• Customized connectors possible
• Compatibility to any common bus system
• Integration of optical rotary joint for a passive optical transmission of bus systems such as Gigabit Ethernet
• Absolute or incremental encoder optional
• Heating elements for low temperature environment optional
