Within the wind turbine industry, double-fed asynchronous generators dominate. In order to address the electromechanical connection needs of these turbines, LTN is proud to offer the SC168 slip ring, a robust slip ring with a universal-hole pattern for different generator types.
The LTN SC168 is a low-maintenance slip ring with high quality contact technology, which has proven to be reliable and cost-effective for many major wind turbine manufacturers globally. It is suitable for wind turbines in the multi-megawatt class with electric pitch systems and is designed to be compact and cost-efficient.
To increase the lifetime of the generator rotor slip rings, and thus reduce the operating costs for the owner, LTN developed this high-quality, low-maintenance generator slip ring featuring a universal-hole pattern. It incorporates a multi-phase rotor which is connected using terminal bolts. The slip ring is made from high-grade insulation and contact materials and the special design reduces abrasion at the brushes, allowing long creepage distances and preventing voltage flashovers.
The modular design of the SC168 slip ring can easily be adapted to specification. Auxiliary components such as heaters, encoder or fiber optical rotary joints can be seamlessly integrated as well. Optimal transfer of data for Ethernet-based field buses, PROFIBUS, CAN-bus or similar field buses can also be achieved when using this slip ring.
