IP65 Variable Propeller Signal Slip Ring Power Supply Control
IP65 Variable Propeller Signal Slip Ring with Power Supply Control for Wind Turbine
Description
JINPAT has developed a com-prehensile standard programmed that is able to offer optimum solutions. Slip ring bodies can be supplied either as open slip ring bodies to be built per customers’ requirements or in a housing of impact-resistant plastic or sheet metal.
A slip ring is mounted on the hub with the same speed on the shaft. It prevents rotation through the suspension support. The slip ring is connected to the shaft of the gearbox and its interface should match the shape and dimensions of the gearbox shaft.
