Ingiant Brass Material Large Current Slip Ring

Product Description

    Our 130mm OD high-current slip ring is a premium rotary electrical connector engineered exclusively for the extreme demands of construction machinery. With 4 dedicated 200A power channels and IP65 dust/waterproof protection, it ensures uninterrupted power transmission between stationary and rotating components in excavators, mobile cranes, aerial work platforms, and other heavy construction equipment. Designed to withstand vibration, shock, and extreme weather, this slip ring is the ultimate solution for reliable performance in the toughest job sites.

Core Design & Performance Features

1. 4x200A High-Current Power Channels 4 fully independent 200A channels support high-power three-phase power transmission + auxiliary power, meeting the heavy load requirements of construction machinery’s rotating systems (e.g., excavator booms, crane turrets). The parallel-stranded copper wire design minimizes resistance and heat generation, ensuring stable power output even under continuous heavy load. 
2. IP65 Harsh Environment Protection IP65-rated sealing provides complete protection against dust ingress and water jets from any direction, making it ideal for outdoor construction sites with rain, mud, dust, and vibration. The sealed housing prevents contamination of internal contact components, drastically extending service life and reducing maintenance. 
3. 130mm Compact Robust Structure The 130mm outer diameter balances compact installation space and high current capacity, suitable for integration into the limited space of construction machinery turrets and rotating joints. The rugged metal housing is reinforced for shock and vibration resistance, withstanding the extreme mechanical stress of heavy equipment operation. 
4. Premium Materials & Military-Grade Reliability
   • Precious metal alloy contact system: Ensures ultra-low contact resistance, minimal electrical noise, and long-term wear resistance, even in high-vibration environments.
   • PTFE (Teflon) insulation: Offers excellent high-temperature resistance (-40°C to +120°C), chemical corrosion resistance, and dielectric strength, suitable for extreme temperature job sites.
   • Tin-plated copper conductors: Superior conductivity and anti-oxidation performance, preventing performance degradation in long-term outdoor use.
   • Color-coded wires: For error-free installation, maintenance, and troubleshooting. 

Application Scenarios

• Construction Machinery: Excavators, mobile cranes, aerial work platforms, concrete pumps, rotary drilling rigs
• Heavy Industrial Equipment: Port cranes, mining machinery, tunnel boring machines
• Offshore & Marine Equipment: Offshore cranes, shipboard rotating systems
• Other Heavy-Duty Rotating Systems: Wind turbine pitch systems, industrial rotating tables
