Power Capsule Slip Rings provide electrical transfer between stationary and rotating platforms in a compact, integrated capsule design.

What is a Power Capsule Slip Ring?
These devices integrate rotor, stator, bearings and protective casing into a single compact capsule to transfer AC and DC electrical power between stationary and rotating assemblies. They use silver rings with graphite brushes and silver-graphite contacts engineered to withstand high temperatures generated during overloads. Insulation materials offer high dielectric strength to prevent short circuits in humid environments, and enclosures can be specified hermetically sealed for contamination-sensitive applications.

Key applications

• High-energy lasers
• Radar antennas
• Defense turrets

Technical specifications

• Supports: AC and DC power transmission
• Contacts: silver rings with graphite brushes; silver‑graphite contacts for overload temperature resilience
• Insulation: materials with high dielectric properties to avoid short circuits, including in humid conditions
• Enclosure: hermetically sealed option available to protect internal components
• Design: compact capsule integrating rotor, stator, bearings and protective casing
• Maintenance: engineered for long-term operation without lubrication or component replacement
• Integration: compatible with other rotary joints such as FORJ (fiber optic rotary joints), hydraulic or RF/hyperfrequency solutions
