High-Current Multi-Channel Slip Ring for Amusement, Marine and Radar Rotary Equipment

Large outdoor special-purpose rotary equipment such as giant Ferris wheels, revolving theaters, shipborne radars, and offshore lifting devices operate for extended periods in harsh environments characterized by vibration, large temperature differentials, and high humidity. These conditions impose higher standards on the load capacity, insulation protection, and structural adaptability of conductive slip rings. The customized hollow-shaft multi-channel conductive slip ring perfectly matches the application scenarios of various special-purpose equipment.

Outdoor special-purpose equipment generally requires coaxial pipe routing and multi-circuit simultaneous power supply. This slip ring features a hollow main shaft with ample through-hole space, allowing the equipment's central drive shaft and water supply/drainage pipes to pass through. Multiple independent conductive channels can simultaneously carry high-power lighting and drive motor power, as well as low-level signals for lighting control, radar data, and safety detection, with separate wiring for power and signal circuits that do not interfere with each other. The gold-plated thickened copper rings, paired with highly wear-resistant carbon brushes, resist high and low temperatures and oxidation. Even in marine high-salt-fog environments and outdoor amusement facility conditions with large temperature variations, they maintain stable conductive performance without issues such as poor contact or signal lag.

The split dual-end wiring design accommodates the differentiated wiring needs of special-purpose equipment: the rotating load side is concentrated on the left-side insulated terminal block, while the fixed power supply side is distributed across the upper and lower carbon brush terminals. The separated wiring layout prevents cable cross-tangling and facilitates waterproof cable management for outdoor equipment. The black thickened aluminum alloy flange offers excellent vibration resistance. When continuous vibrations are generated by ship navigation or high-speed rotation of amusement equipment, the internal structure of the slip ring does not loosen or shift, ensuring stable conductive contact.

In the cultural tourism and amusement industry, Ferris wheels and 360° revolving theaters rely on this slip ring to continuously supply power to cabin lighting, air conditioning, and audiovisual equipment, enabling full-circle unrestricted rotation. Shipborne radars and offshore crane slewing mechanisms use the hollow slip ring to solve rotary power transmission challenges under high-humidity and vibrating marine conditions, eliminating short-circuit faults caused by seawater corrosion. Vehicle-mounted satellite rotating antennas are equipped with the slip ring to stably transmit signals and power, ensuring continuous equipment operation during movement.

This industrial-grade hollow conductive slip ring supports customized channel count, rated current, and flange dimensions to suit all types of rotary equipment across engineering machinery, cultural tourism, marine, and military testing sectors. With its four core advantages—high integration, high current capacity, hollow through-shaft design, and easy maintenance—it has become a standardized conductive solution for special-purpose rotary equipment across multiple industries.
