Wind Slip Ring with Connector Coupler and Mates

Posted on Tuesday, April 19, 2016 in UEA Blog


image001This new electrical slip ring has progressed beyond the design phase and is about to make its way into production at United Equipment Accessories. The S15D series slip ring with connector coupler mounting tube assembly was designed to be installed horizontally in a wind turbine application. The customized mating coupler and Harting hood connectors are also being supplied to make this design completely plug and play. This particular application requires five circuits for power and 17 circuits for control and communication.

image003The S15D series 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 clam shell 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.

image005The mating coupler is bolted to the gearbox of the wind turbine 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 your slip ring needs.
