Industrial slip ring

for offshore applicationsmarinefor cranes

Short Description
High-Current Slip Ring (180 mm OD, 4 independent power channels, 400 A per channel). Designed for ultra-high-power rotating systems in heavy industry, construction and marine applications, offering continuous 400 A per channel with IP65 protection and high resistance to shock and vibration.

Product Description
This 180 mm outer-diameter high-current slip ring is a rotary power connector engineered for heavy-duty rotating equipment such as cranes, drilling rigs, turrets and large rotating platforms. It provides four fully independent power channels rated at 400 A each, enabling large-scale power transfer with low contact resistance and reduced heat generation. Constructed from high-conductivity copper alloys and precious-metal brush contacts, it is optimized for long service life in high-vibration and extreme-temperature environments.

Core Design & Performance Advantages

• 4×400 A Ultra-High Power Capacity: Four independent channels deliver stable, continuous high current for heavy industrial rotating equipment, with multi-strand copper conductors minimizing resistance and heat.
• 180 mm Rugged Outer Diameter Structure: Large-diameter housing reinforced for structural stability and heat dissipation; integrated sealing protects against dust, water and oil.
• Harsh Environment Reliability: Engineered for shock and vibration resistance, wide operating temperatures and reliable sealing for outdoor and marine conditions.

Reliability & Maintenance

• IP65 dust/waterproof rating resists rain, mud and water jets (IP67 option available).
• Shock and vibration resistance per industrial standards ensures stable contact performance during heavy-duty operations.
• High-temperature PTFE insulation and anti-oxidation conductors maintain performance from -40°C to +150°C.

Low Heat & Low Maintenance Design
Precious-metal alloy brush contacts reduce contact resistance and friction heat, lowering operating temperature and extending service life. Color-coded high-current cables simplify installation and maintenance. Customizable wiring terminals and connectors adapt to varied machine interfaces.

Application Scenarios

• Heavy Construction Machinery: large mobile cranes, rotary drilling rigs, concrete pump trucks, aerial work platforms
• Industrial & Port Equipment: gantry cranes, ship unloaders, rotating robot turntables
• Marine & Offshore: offshore drilling platforms, shipboard rotating systems, marine cranes
