Ring Current Collectors

A ring current collector is a device for transmitting electrical energy and signals from stationary parts to rotating parts. Applications: electric motors, rotary cranes (tower, truck, portal cranes), quarry excavators, reclaimers, sludge pumps (sludge scrapers) at water treatment plants, amusement rides (children's carousels), manipulators, molding and packaging machines, wind power plants and cable drums, antennas, radars.

There are many places, where there is a vital need to transmit electric power and electrical signals from stationary to rotating units in all types of machines/ For instance: in revolving cranes, rotating purifiers in sewage or water treatment facilities, carrousels, manipulators, wrapping machines, radar and antenna dishes, wind turbines, cable reels and many other applications. Industrial slip ring assemblies provide simple, reliable and cost-effective solution to this engineering problem.

Our standard program allows to assemble slip ring assemblies for energy and data transfer with any number of poles, for nominal current up to 1200 A and voltages up to 24 kV. Slip ring assemblies diameters vary from 30 mm up to 360 mm and can have up to 100-poles.

Slip ring assemblies can be supplied either as open, “non-enclosed” types for special customer adaptations, or totally enclosed with shockproof plastic or galvanised steel housing even for hazardous locations. Additional rotating couplings are available for fluids or gases transfer. Fiber optic swivels can be integrated.
