High-Voltage Shore Power Cable Management System (HVSP-CMS)

1. Core Philosophy: Precision Engineering & Total Autonomy

Our Shore Power Cable Reel is not just a collection of parts; it is a meticulously engineered system designed for the most demanding maritime environments. By maintaining full-spectrum in-house autonomy—from R&D to final assembly—we ensure that every "Energy Bridge" we build delivers unparalleled reliability, safety, and efficiency.

2. Advanced Core Components (Technical Deep-Dive)

I. High-Performance Slip Ring Assembly (In-House R&D)

100% Proprietary Technology:Engineered and manufactured entirely in-house. We have eliminated external technical dependencies to ensure the "DNA" of our core transmission is under total quality control.

Precision Manufacturing:Utilizing Micron-level CNC machiningand modular assembly fixtures. The copper conductor core is processed under strict tolerances to handle high-voltage, high-speed, and heavy-load scenarios with zero loss in power or signal integrity.

II. Heavy-Duty Double Chain & Sprocket System

Redundant Reliability:Designed for heavy-load scenarios, our dual-chain structure provides a "Safety Mirror."If one chain encounters an issue, the backup system ensures zero downtime.

Synchronous Engagement:Precise meshing of double sprockets eliminates vibration and offset, significantly reducing transmission loss and mechanical wear.

III. Intelligent Reducer & Transmission System

Specialized Braking Characteristics:Our self-developed gearboxes feature a unique "Safe-Release" mechanism. In extreme failure scenarios, the cable can still be safely pulled out manually to prevent catastrophic equipment damage.

Stepless Speed Regulation:Supports smooth starts and infinitesimal speed adjustments, matching the load dynamically and protecting the entire drivetrain from torque spikes.

IV. German-Precision Monitoring & Counting

High-End Cam Limiters:Equipped with imported German cam limiters, offering the industry’s highest precision and longest service life.

Multi-Stage Alert Logic:
Level 1:Two turns remaining (Visual & Signal feedback).
Level 2:Final turn remaining (Critical alert & Interlock).
Level 3:Full-reel auto-stop (Preventing mechanical over-tension).

3. Fail-Safe Architecture: Emergency & Upgrade Solutions

We understand that at sea, "failure is not an option." Our systems include specialized response layers for every contingency.

Safety Solution	Contingency Scenario	Technical Execution
Chain-Break Auto-Brake	Mechanical chain failure	Sensors detect slack or break instantly; an integrated electric linear actuatorengages a mechanical slider to lock the reel.
Emergency Recovery System	Primary motor or gearbox failure	System activates a dedicated backup motor and reducer, allowing the crew to safely retract the cable despite a total main-drive loss.
VFD + Hydro-Viscous Tension Control	Severe surge loads or cable snags	The VFD regulates torque during normal flow. During ship surges or snags, the Hydro-Viscous Reducerenters a "Slip State," isolating the motor from the impact load.

4. Intelligent Tension Management (Advanced Upgrade)

For vessels operating in volatile waters or high-traffic terminals, our VFD + Hydro-Viscous Driveprovides the ultimate protection:

Active Regulation:The Variable Frequency Drive (VFD) maintains constant tension based on real-time feedback.

Kinetic Isolation:When a vessel is hit by a sudden surge or the cable is snagged, the hydro-viscous unit acts as a "mechanical fuse." It allows the cable to slip safely, absorbing the kinetic energy before it can damage the delicate high-voltage motor or internal wiring.
