400Hz Ground Power Cable
TEBAOFLEX BETAjet 400FRNC-quadroflex is an open-twisted, high-flexibility 400Hz ground power cable designed for airport ground support equipment (GSE), mobile Ground Power Units (GPUs), and passenger boarding bridges (PBB).
- Dual Certified: Fully compliant with European CE (No. ICR/VC/HTT260331) and North American UL (File E553318, Standard UL 62).
- Engineered for Tough Environments: Features cross-linked Ethylene-Propylene-Rubber (EPR) core insulation and a highly abrasion-resistant Polyurethane (PUR) safety-orange outer sheath.
- Excellent Potential Separation: Open-twisted construction reduces asymmetrical voltage drops and mitigates electromagnetic interference (EMI).
- Optimized Termination: Central control cable with $8 \times 1\text{ mm}^2$ tinned copper conductors allows simplified connector harnessing.
BETAjet 400FRNC-quadroflex 400Hz Ground Power Cable
In modern aviation ground support operations, the transmission of 400Hz medium-frequency power requires cables capable of withstanding extreme mechanical dragging, UV exposure, chemical fluids (such as aviation fuels and deicing agents), and continuous dynamic flexing. BETAjet 400FRNC-quadroflex, engineered by Jiangsu Tebaoflex Special Cable Co., Ltd. (TEBAOFLEX), is built specifically to address these challenges on airport aprons, under-floor pit systems, and passenger bridge cable dispensers.
Structural Composition & Material Science
- Power Conductors: Bare fine copper strands compliant with VDE 0295 and IEC 60228 standards. Conductor flexibility is optimized via Class 5 or Class 6 engineering, allowing tight dynamic bending radii.
- Core Insulation: Cross-linked Ethylene-Propylene-Rubber (EPR), providing exceptional dielectric strength and heat resistance under continuous load.
- Central Control Assembly: Comprises 8mm tinned Class 5 copper conductors insulated with Polyolefin Copolymer. Standard white cores with clear sequential black numbering for error-free installation.
- Outer Sheath: Formulated from premium wear-resistant Polyurethane (PUR), colored safety orange. It offers robust defense against tearing, dragging abrasion on concrete, oil penetration, and UV degradation.

- Underground Pits: Heavy duty performance in damp, retractable under-floor ground service pits where water or glycol mixtures may collect.
Frequently Asked Questions (FAQ)
Q1: Does TEBAOFLEX provide pre-assembled 400Hz cables with aircraft connectors?
Yes. Jiangsu Tebaoflex provides complete factory-tested and harnessed assemblies complete with standard 400Hz aircraft plugs (such as standard R67 or 6-pin molded plugs) upon inquiry. We provide turnkey ground support solutions ready for installation.
Q2: Why is the maximum recommended cable length specified as 15 meters?
Due to the electromagnetic dynamics of high-frequency 400Hz power transmissions, longer cable lengths can experience asymmetric voltage drops, which might affect the power supply standards of high-precision aircraft electronics. For custom configurations exceeding 15 meters, please contact our technical department for custom engineering evaluations.
Q3: How does the PUR outer jacket perform compared to traditional PVC in airport environments?
Traditional PVC cables tend to harden, crack, and lose flexibility under extreme sub-zero weather or hot apron tarmac, and they show minimal resistance to jet fuel. TEBAOFLEX’s custom PUR (Polyurethane) outer sheath maintains high mechanical flexibility down to -40°C, possesses premium tear/abrasion resistance when dragged over concrete, and completely resists aviation oils and glycol-based deicing fluids.
