400Hz Ground Power Cable | Aviation GPU Power | TEBAOFLEX
High-Performance Flexible Power for Aviation Tarmacs Designed for the extreme mechanical stress of civil and military airport operations, our flexible 400Hz ground power cables ensure uninterrupted voltage delivery. Featuring an abrasion-resistant PUR sheath and integrated double-insulated control cores for precise voltage sensing, these cables survive where standard options fail.
- Core Advantage: Easy feedback of sense voltage & superior weather resistance.
- Direct from Factory: Custom harnessing and bulk wholesale available.
400Hz Ground Power Cable: Engineered for Aviation Reliability
Airport tarmac operations require uninterrupted power transmission under severe weather, chemical exposure, and constant mechanical stress. Standard cables often degrade quickly in these environments. Our flexible 400Hz ground power cables are specifically engineered by our factory to provide exceptional durability and stable voltage delivery for high-mobility aviation applications.
Key Engineering Advantages
- Extreme Mechanical Durability: Constructed with a high-visibility yellow Polyurethane (PUR) outer sheath. This provides excellent resistance to abrasion, ensuring the cable survives the intense daily wear and tear of being dragged across concrete aprons.
- Integrated Voltage Sensing: Features 4×1 mm² tinned fine copper control cores that are double-insulated and integrated directly into the phase conductors. This specific configuration allows for the easy feedback of sense voltage, ensuring precise operational control for the Ground Power Unit (GPU).
- Broad Climate Tolerance: Designed to operate safely in both indoor and outdoor extreme climates. The cross-linked EPR core insulation maintains flexibility and performance across a strict temperature range of -40°C to +90°C, alongside excellent UV and oil resistance.
- Strict Safety Compliance: Engineered for critical infrastructure, the cable is completely halogen-free, flame retardant, and produces low toxicity and low corrosivity of gases during a fire incident, strictly meeting IEC and EN standards.

Primary Application Scenarios
These heavy-duty ground power lines are highly suitable for mobile applications subject to exceptional operational conditions. Typical global installations include:
- Grounded Pits: Power delivery from underground tarmac distribution systems.
- Mobile Generators: Connectivity for mobile 400 Hz diesel generator units.
- Passenger Boarding Bridges: Suspended cable routing for civil and military aviation facilities.
(Professional Note: The integrated control cores are designed strictly for voltage sense applications only. Due to asymmetric voltage drop, the recommended maximum cable length for this specific open-twisted configuration is 15 meters. For longer routing, please contact our engineering team for the deltaflex alternative.)
Frequently Asked Questions (Technical & Procurement)
Q1: How does this cable withstand the severe mechanical stress on airport aprons?
A: Standard PVC cables harden and crack under constant dragging and tarmac temperature fluctuations. Our 400Hz ground power cable utilizes an abrasion-resistant Polyurethane (PUR) outer sheath combined with highly flexible Class 6 tinned copper strands. This ensures maximum flex life and resistance against concrete friction, aviation fuels, and heavy equipment run-overs.
Q2: How is the sense voltage feedback managed without signal interference?
A: This cable features a specialized 4-core open twisted design. We integrate $4\times1~mm^{2}$ tinned fine copper control cores directly into the phase conductors. These control cores feature polyolefin copolymer double insulation, ensuring accurate voltage sensing feedback without signal degradation.
Q3: Why is the maximum recommended length limited to 15 meters for this specific cable?
A: In this 4-core configuration, asymmetric voltage drop can occur over longer distances. To maintain the exact 115/200V operational stability required by aircraft systems, our engineers recommend a 15-meter limit. If your project requires longer runs, TEBAOFLEX manufactures alternative geometries (such as our deltaflex configurations) to eliminate this issue.
Q4: As a direct manufacturer, can TEBAOFLEX provide custom harnesses or connectors?
A: Yes. Because we operate our own manufacturing facility and laboratory, we don’t just sell bulk drums. Upon request, we can deliver these cables inclusive of specialized harnessing and aviation-standard plugs, reducing installation time for your EPC project.
