400Hz Feeder Cable | LSOH Static Aviation Power
Heavy-Duty Static Power Distribution for Aviation Infrastructure Routing 400Hz power from substations to terminal gates requires cables that combat both electrical skin effect and harsh underground environments. Our LSOH 400Hz feeder cables are engineered for static installations, offering exceptional ageing stability, direct burial capabilities, and natural rodent resistance without the need for bulky armor.
- Core Advantage: Flexible conductors optimized to reduce 400Hz skin effect.
- Durability: Skydrol resistant (>1000h) and naturally termite/rodent proof.
- Safety: Low Smoke Zero Halogen (LSOH) for critical civil/military safety.
- Direct from Factory: Bulk manufacturing for global airport EPC projects.
400Hz Feeder Cable: Reliable Power Routing for Airport Infrastructure
Laying power lines in airport cable trays, underground tubes, or directly in the soil exposes cables to moisture, rodents, and corrosive aviation fluids. Furthermore, transmitting 400Hz alternating current over long static distances introduces significant electrical resistance due to the skin effect. Engineered specifically for fixed installations, TEBAOFLEX’s 400Hz feeder cables resolve these infrastructure challenges, delivering stable, long-lasting power from ground substations to aircraft docking areas.
Key Engineering Advantages
- Optimized for 400Hz Skin Effect: Instead of using solid metal cores that suffer from high AC resistance at 400Hz, our power conductors utilize finely stranded bare copper (Class 5). This highly flexible configuration maximizes the surface area, effectively mitigating the skin effect and reducing voltage drop over long installation runs.
- Direct Burial & Rodent Proof: The specialized Polyolefin Copolymer outer sheath is naturally resistant to termites and rodents. It provides this biological protection without relying on toxic chemical repellents or heavy steel armor, making trench laying and duct installation significantly easier for EPC contractors.
- Aviation Chemical Resistance: Airport environments expose infrastructure to harsh chemicals. This cable is rigorously tested to be Skydrol-resistant for over 1000 hours at 50°C, ensuring the jacket will not degrade when exposed to corrosive aircraft hydraulic fluids.
- LSOH Safety Compliance: Unlike traditional PVC cables that release toxic black smoke during a fire, our feeder cables are completely halogen-free and generate very low smoke density. This complies with stringent international safety standards, such as IEC 60754 for halogen-free materials, safeguarding personnel in enclosed radar stations and military facilities.

Primary Application Scenarios
This cable is exclusively designed for static installations under normal mechanical stress. Typical EPC deployments include:
- Underground Infrastructure: Direct laying in the ground, outdoor shafts, and protective routing tubes.
- Cable Trays: Long-distance power routing within airport terminal structures.
- Critical Facilities: Flexible wiring of UPS units, radar substations, and military broadcasting equipment.
(Note: This cable does not meet the requirements for indoor applications according to IEC 60332-3 and EN 50266-2. For specific indoor fire-rated routing, contact our engineering team.)
Frequently Asked Questions (Technical & Procurement)
Q1: How does this feeder cable differ from your standard flexible ground power cables? A: Standard ground power cables are built for constant movement and abrasion on the tarmac. Our 400Hz feeder cable, however, is designed for “static” or fixed installations (like underground trenches or cable trays). It prioritizes long-term ageing stability, direct burial capability, and skin-effect reduction over long distances, rather than extreme mechanical torsion.
Q2: How does the cable achieve rodent and termite resistance without steel armor? A: Traditional underground cables use heavy steel tape or wire armor to prevent rodent damage, which makes the cable stiff and hard to install. Our engineers utilize a highly specialized, dense Polyolefin Copolymer outer sheath that is biologically unappealing and physically tough enough to deter rodents and termites naturally, saving significant installation time and cost.
Q3: Why use XLPE insulation for the phase conductors instead of EPR? A: For static power distribution, Cross-linked Polyethylene (XLPE) offers superior dielectric strength and excellent long-term thermal ageing stability compared to standard rubber. It ensures that the cable maintains peak electrical performance and insulation integrity over decades of continuous 600/1000V operation in underground environments.
Q4: Can TEBAOFLEX provide custom lengths and cross-sections for major airport projects? A: Yes. As a primary manufacturer operating our own extrusion and testing facilities, we supply directly to global EPC contractors. Whether you need the standard 1×35 + 6×35 + 6x(4×1) mm² configuration or the higher-capacity 1×50 mm² version, we can produce custom drum lengths optimized to reduce splicing and material waste on your specific job site.
