Looking for a slip ring that is easily installed? UEA offers slip ring designs that plug right into place, requiring no installation wiring. This slip ring with connector coupler mounting tube assembly was designed to be installed horizontally in a wind turbine. The customized mating coupler and Harting hood connectors were supplied to make this design completely plug and play. This particular wind turbine required five circuits for power and 17 circuits for control and communication.

This slip ring is in our 1.50" bore slip ring group and is made up of an anodized aluminum dished base casting, anodized aluminum top plate, and a molded clamshell-style cover. The extra tall, dished base casting allows room to mount multiple Harting housings. A vent plug and thermostat-controlled heater were added to eliminate condensation inside the enclosure. An adjustable torque arm with rod end bearings is supplied to retain the outer part of the slip ring.

The mating coupler is bolted to the wind turbine's gearbox after first connecting the typically longer center rotational harness. The slip ring is then plugged into the mating half allowing ease of installation.  The guide pins of Harting's Han-Modular® system ensure proper alignment of the connectors. The modular connectors and the mating half bolt pattern can be customized to meet the slip ring requirements.
