2. Cable Construction & Design
The TENAX-FEST H07VVH6-F-LED is built using a modular construction approach with five distinct functional layers, each engineered to provide electrical protection, mechanical durability, and integrated LED functionality.
Inner Construction (Core → Out)
Flexible Copper Conductors (Class 5): FeiChun uses extra-fine stranded Class 5 copper conductors per IEC 60228, enabling superior flexibility for high-speed festoon applications. Conductor identification follows HD 308 S2 colour coding standards: 4-core configurations use black, grey, green-yellow (earth), and brown; 5-core adds blue (neutral); cores above 5 are numbered.
PVC Core Insulation: Each conductor is individually insulated with premium PVC compound meeting IEC 60227 Part 6 requirements. Stripping threads are strategically placed between core groups to facilitate outer sheath removal without damaging core insulation—critical for on-site maintenance.
Inner PVC Sheath: A protective PVC layer bundles all insulated conductors, providing mechanical protection and core positioning for the flat geometry. This sheath ensures core stability during high-speed reeling and prevents conductor migration during flexing cycles.
FC-CVD™ Module (Edge-Mount): FeiChun’s proprietary capacitive voltage divider is mounted at the cable edge, harvesting LED power from the 450/750 V field via capacitive coupling. The edge-mount configuration ensures zero impact on core arrangement or cable flexibility while maintaining galvanic isolation between the LED circuit and power conductors. This innovation eliminates the need for external DC supplies, control panel modifications, or additional installation costs.
LED Strip (Warning Red 620–630 nm): Premium silicone-encapsulated warning-red LEDs run continuously along the cable edge. This high-wavelength red (620–630 nm) provides excellent visibility across day and night lighting conditions while minimizing eye strain. FC-ASB™ aramid stress braid protects the LED assembly from mechanical damage during deployment and festoon cycling.
FC-TPU™ P-Series Translucent Outer Sheath: The final layer is FeiChun’s proprietary FR-TPU thermoplastic polyurethane (P-Series, Formula FC-2026-TPU-P4), engineered specifically for festoon applications. This translucent material maintains LED light transmission even after 100,000+ festoon travel cycles at 120 m/min, providing long-term visibility assurance.

6. FC-CVD™ Technology & LED Operation
The FC-CVD™ (FeiChun Capacitive Voltage Divider) is the enabling innovation behind TENAX-FEST LED’s self-powered operation. Unlike systems requiring separate DC power supplies or battery-powered solutions, FC-CVD™ harvests energy directly from the 450/750 V AC field through capacitive coupling, ensuring continuous LED illumination whenever the cable is energized.
Operating Principle
Capacitive voltage dividers work by creating a high-impedance voltage dividing network between phase and neutral/earth. The incoming AC field (450–750 V) is stepped down to a safe low-voltage level (typically 12–24 V DC after rectification) through precisely engineered capacitive elements. This harvesting method provides two critical advantages: galvanic isolation from the power circuit (preventing electrical shock hazards) and zero maintenance requirements (no batteries, inverters, or external power connections).
Safety & Performance
FeiChun’s FC-CVD™ module incorporates multiple protection layers: magnetic saturation capacitors prevent voltage transient propagation, TVS diodes provide picosecond clamping of crane motor inrush currents, Zener diodes regulate output to safe 12/24 V DC levels, and PTC resettable fuses auto-reset without manual intervention. This multi-layer approach ensures the LED circuit remains protected during fault conditions, motor starting transients, and emergency brake events.
Plug-and-Play Compatibility
TENAX-FEST LED requires zero control panel modification. Simply disconnect the standard H07VVH6-F cable and connect the LED version—the FC-CVD™ module automatically activates upon energization. This “Plug-and-Play” approach minimizes installation time and reduces commissioning risks.
LED Specifications
The integrated LED strip operates at warning-red wavelength (620–630 nm), chosen specifically for high visibility across day-to-night transitions and low-light factory environments. Red LEDs penetrate ambient lighting better than blue or white alternatives and produce less eye fatigue during extended observation. The silicone encapsulation protects LEDs from moisture, UV exposure, and mechanical impact while maintaining translucency for effective light transmission through the FC-TPU™ outer sheath.
7. FC-TPU™ P-Series Outer Sheath
The FC-TPU™ (FeiChun Thermoplastic Polyurethane) P-Series outer sheath represents FeiChun’s 2026 advancement in festoon cable durability and optical clarity. Standard PVC sheaths are susceptible to abrasion, hardening, and opacity loss when subjected to repeated festoon cycling. The FC-TPU™ P-Series delivers superior performance across multiple demanding criteria.
Abrasion Resistance
Independent testing shows FC-TPU™ P-Series provides 3–5× greater abrasion resistance compared to standard PVC sheaths when tested under festoon roller contact conditions. This extended durability translates to longer cable service life, reducing replacement frequency and total cost of ownership in high-speed applications.
Optical Transparency
FC-TPU™ maintains visible light transmission even after 100,000+ festoon travel cycles at 120 m/min. Standard PVC sheaths progressively lose transparency as surface stress-whitening accumulates. By maintaining clarity, the LED strip remains visible throughout the cable’s operational life, ensuring safety assurance from day one through end-of-life.
Environmental Resistance
FC-TPU™ P-Series is inherently resistant to oil, acid, alkaline solutions, UV radiation, ozone, and moisture. This chemical versatility qualifies TENAX-FEST LED for both indoor factory environments and outdoor port terminal applications. The material is rated for continuous operation from −25 °C (mobile/outdoor) to +60 °C, suitable for tropical climates (Vietnam, Southeast Asia) and temperate European installations.
Flame Retardance
FC-TPU™ P-Series is self-extinguishing per IEC 60332-1, meeting fire safety requirements for industrial installations. Halogen-free formulations are available on request, supporting facilities with elevated environmental or regulatory requirements.
8. FC-SPM™ Surge Protection System
Overhead crane systems are inherently exposed to electrical transients: motor inrush currents, emergency brake pulses, switching transients, and lightning-induced surges. The FC-SPM™ (FeiChun Surge Protection Module) integrated within TENAX-FEST LED provides four-layer transient protection specifically engineered for industrial festoon environments.
| Protection Layer | Component Technology | Function | Operating Principle |
|---|---|---|---|
| Layer 1 | Magnetic Saturation Capacitors | Energy clamping at source | High-frequency energy dissipation |
| Layer 2 | TVS Diodes (Transient Voltage Suppressors) | Picosecond transient clamping | Crane motor inrush suppression |
| Layer 3 | Zener / LDO Regulators | Voltage regulation to 12/24 V DC | Cold-rated to −25 °C for outdoor operation |
| Layer 4 | PTC Resettable Fuses | Overcurrent protection, auto-reset | Zero-maintenance fault recovery |
Unlike traditional fuses requiring manual replacement, the PTC resettable approach automatically restores circuit operation once fault conditions clear. This design philosophy eliminates emergency downtime and reduces maintenance labor for 24/7 port terminal operations.
9. Installation, Marking & Safety
Cable Marking
TENAX-FEST H07VVH6-F-LED cables are marked per HD 359 S2 / IEC 60227 standards with the following information printed continuously along the cable surface: conductor count, conductor cross-section (mm²), “FEICHUN” manufacturer identification, production year (2-digit), and production week (2-digit).
Example marking: “07VVH6-F 4G10 FEICHUN 26 15” indicates 4-core, 10 mm² cable manufactured in week 15 of 2026.
Installation Best Practices
TENAX-FEST LED is designed as a direct drop-in replacement for standard H07VVH6-F cables in existing festoon systems. Installation steps are straightforward: (1) De-energize the existing cable and disconnect from terminal boxes; (2) Remove the old H07VVH6-F cable from the festoon system; (3) Carefully feed the TENAX-FEST LED cable through existing cable carriers, guides, and support clips; (4) Connect power and control conductors to their respective terminals using standard crimped connectors or solder joints; (5) Energize the system and visually confirm LED illumination along the entire cable route.
The cable is suitable for indoor and outdoor installations, with mobile festoon service temperature range −25 °C to +60 °C. For fixed installations, the range extends to −35 °C to +60 °C.
Safety Considerations
Workers should always assume the TENAX-FEST LED cable is energized if the festoon system is powered. The integrated FC-CVD™ LED circuit provides a visual indicator of energization: a glowing red LED strip confirms the cable is “live” and ready for operation. This “live cable indicator” is a critical safety feature for lockout/tagout (LOTO) procedures in environments where crane circuits may be energized during maintenance or emergency situations.
Electrical Safety Warning
TENAX-FEST H07VVH6-F-LED operates at 450/750 V AC. Treat the cable as live whenever the crane power switch is in the “on” position. Always use proper LOTO procedures, insulated tools, and personal protective equipment (PPE) when working near energized cables. The LED’s visual indication confirms energization—do not rely solely on the absence of LED illumination to assume the cable is de-energized.
10. Key Advantages & Competitive Positioning
The TENAX-FEST H07VVH6-F-LED integrates multiple innovations that differentiate it from standard festoon cables and competing LED solutions.
Industry First: Self-Powered LED Festoon Cable

Competitors either require external DC supplies, control panel modifications, or battery-powered alternatives. FeiChun’s FC-CVD™ approach eliminates these complications while delivering reliable illumination across the full 450–750 V operating range.
Plug-and-Play System Integration
Zero installation complexity: TENAX-FEST LED directly replaces standard H07VVH6-F cables without any electrical infrastructure changes. No inverters, no control boards, no power supply upgrades—simply swap the cable and energize. This characteristic minimizes installation labor, reduces technical risk, and accelerates time-to-value for customers.
Continuous Cable Route Visibility
A glowing red LED strip along the entire cable length provides instant visual confirmation of cable location during night-shift operations, low-light factory environments, and busy port terminals. This continuous visibility prevents accidental cable entanglement, reduces crush injuries, and improves worker safety during fast-paced material handling operations.
High-Speed Festoon Compatibility
Rated for 120 m/min festoon speeds with dynamic tensile strength of 30 N/mm², TENAX-FEST LED is fully compatible with modern high-speed crane systems. The FC-TPU™ P-Series sheath and aramid stress braid protect the LED assembly while maintaining mechanical integrity through thousands of complete reeling cycles.
Durability & Extended Service Life
FC-TPU™ P-Series delivers 3–5× abrasion resistance compared to standard PVC, with proven durability through 100,000+ festoon cycles at 120 m/min. Independent field testing confirms optical clarity maintenance even after extended service, ensuring the LED remains visible throughout the cable’s operational life.
Maintenance-Free Operation
FC-SPM™ surge protection features auto-resetting PTC fuses—no manual intervention required following transient events. Batteries, external power supplies, and inverters are eliminated, reducing maintenance labor and parts inventory. The cable simply operates whenever the festoon system is energized.
LOTO Safety Enhancement
The integrated LED provides a live-cable indicator, critical for lockout/tagout procedures where workers must distinguish between energized and de-energized lines. The persistent red glow confirms system energization, improving worker confidence and accident prevention during crane maintenance windows.
Vietnam Industrial Zones & Port Terminal Optimization
TENAX-FEST LED is specifically engineered for Southeast Asian industrial environments. The cable’s cold-flex rating (−25 °C to +60 °C) supports tropical port operations in Hai Phong, Ho Chi Minh City (HCMC), Da Nang, and Vung Tau. The material’s UV and ozone resistance qualify it for 24/7 outdoor container terminal operations, where night-shift visibility is critical for safe cargo handling.
