BGB: Wind Brochure


Power & Signal

Slip ring assemblies are used for the transfer of power and data between the hub/blades and the nacelle via the slow speed main shaft. BGB can manufacture custom units that combine power slip rings with signal/optical/hydraulic rotary joints. Power channels utilise Phosphor Bronze rings in conjunction with either Copper graphite or Silver graphite brushes. Signal channels make use of silver to silver contacts, or where applicable, fibre optic rotary joints (FORJs).

Silver provides the best material for reliable signal transfer, and very low signal noise. In most cases, sealed enclosures are used to prevent the ingress of liquids or dust.

BGB can use in-house testing to meet customers required IP rating.
