Power Capsule Slip Rings

Power Capsule Slip Rings transfer high voltage (several kV) or high current (several kA) between stationary and rotating platforms. Their compact capsule design integrates the rotor, stator, bearings, and protective casings, ensuring reliable performance in demanding environments.

What is a Power Capsule Slip Ring?

This technology supports both AC and DC power transmissions. The system combines silver rings with graphite brushes, while silver-graphite contacts withstand the extreme temperatures generated by potential overloads.

The insulation material offers excellent dielectric properties, preventing short circuits even in humid conditions. In addition, a hermetically sealed enclosure protects internal components against external contaminants.

Thanks to their rugged design, these slip rings operate reliably for years without requiring lubrication or component replacement.

They integrate easily with other rotary joints, including FORJ, hydraulic, or hyper frequency solutions.

Key applications

Engineers use these slip rings in demanding systems such as high-energy lasers, radar antennas, and defense turrets.
