Core Design & Performance Advantages
-
4×400A Ultra-High Power Capacity
Four independent 400A channels deliver stable, continuous high power for heavy industrial rotating equipment. The multi-strand copper wire design minimizes electrical resistance and heat loss, ensuring no power drop even under long-term peak loads. Perfect for 3-phase power + redundant power systems in large cranes, rotary drilling rigs, and port machinery. -
180mm Rugged Outer Diameter Structure
The 180mm large-diameter housing is reinforced with high-strength metal, balancing structural stability and heat dissipation. It fits the limited installation space of heavy machinery turrets while supporting ultra-high current, avoiding overheating and deformation during continuous operation. The integrated sealing structure effectively isolates dust, water, and oil contamination. -
Harsh Environment Reliability
- IP65 dust/waterproof protection resists rain, mud, and water jets, suitable for outdoor construction sites and marine environments.
- Shock and vibration resistance (per ISO 10302 standard) ensures stable performance during heavy machinery operation—no contact failure or signal distortion.
- High-temperature PTFE insulation and anti-oxidation conductors maintain performance in -40°C~+150°C extreme temperatures, ideal for all-season industrial use.
- Low Heat & Low Maintenance Design
Precious metal alloy brush-contact structure reduces contact resistance and friction heat, lowering operating temperature and extending service life. Color-coded high-current wires simplify installation, maintenance, and troubleshooting, reducing downtime for large equipment. Customizable wiring terminals and connectors fit diverse machinery interface requirements.
