TEBAOFLEX 400Hz aircraft ground power cable for airport GPU systems, apron power supply, passenger boarding bridges and related ground support equipment. The SII 4x1x70 + 4×1 construction combines four 70 mm2 tinned extra-flexible power conductors with four 1 mm2 tinned control wires in a halogen-free, PUR-sheathed cable. It is intended for projects that need power and control functions in one flexible aviation ground-power cable. The reference construction is rated 600/1000 V, with a stated 207 A per phase at +30 C ambient temperature and a 388 mm minimum bending radius for quad conductors. Confirm the ordered size, connector arrangement, installation movement, colour and documentation scope before procurement.
A 450 m order of 4×(1×70+4×1) 400 Hz cable for a Russian buyer's civil-airport pit system, made up by the buyer in 15 m and 28 m assemblies, is documented on the airport pit system 400 Hz cable case page, from conductor stranding to container loading.
400Hz Ground Power Cable Construction
The reference SII construction combines four power cores and four control cores under halogen-free PUR layers. The integrated control conductors keep GPU control or monitoring wiring with the power route, while the extra-flexible tinned conductors support handling around airport GSE and apron connections.

400Hz Aircraft GPU Cable Applications
Use this cable family where an airport ground-power route must carry 400Hz aircraft power and associated control wiring together. The PUR jacket and high-flexibility construction are intended for equipment and apron environments, subject to the ordered construction and installation conditions.

Buyer selection checks
Send voltage, conductor size, control-core arrangement, cable length, quantity, connector type, reel or routing method, minimum bend requirement, sheath colour and required inspection or documentation scope. Continuous reeling, drum-retriever and fixed routes can require different constructions; confirm the movement duty before substitution.400Hz GPU Cable
A 400Hz GPU cable connects a mobile GPU, grounded pit, passenger boarding bridge or apron service point to the aircraft power interface. Specify whether the route is hand-handled, carried by a bridge, stored in a basket, or used with a reel or retriever; those duties can require different conductor geometry, reinforcement and minimum bend radius.- Mobile 400Hz ground power units and aircraft connector assemblies
- Grounded-pit and apron power routes
- Passenger boarding bridge and hangar service positions
- Connector-ready cable assemblies with voltage-sense or control conductors where required
400Hz GPU Cable FAQ
Can the cable be supplied with an aircraft connector? Yes, connector-ready and harnessed assemblies can be quoted when the plug type, control contacts, length, test scope and field-service requirements are specified.Are 4 x 1 mm2 control cores always required? No. They are used in some constructions for voltage sensing or control. Confirm the aircraft interface and equipment wiring before selecting the control-core arrangement.Does every 400Hz cable suit a drum or retriever? No. Continuous winding, drum diameter, tension, layering and cycle count need a purpose-designed reeling construction.400Hz Aircraft Ground Power Cable Specifications

4×(1×70+4×1) Construction Built for a 400 Hz Airport Pit System
In September 2026 TEBAOFLEX made 450 m of this construction for a civil-airport pit system: four separately sheathed cores twisted together, with no overall sheath. The buyer cuts it into 15 m and 28 m lengths and assembles them itself. Each of the four cores holds one 70 mm² power conductor and four 1 mm² control cores, 16 control cores in total, while the reference SII 4x1x70 + 4x1 construction above has four control wires in the whole cable. It is a project construction, not a version of SKU 5025-1: the control cores run inside each sheathed core rather than in a central control-core assembly.| Item | 4x(1x70+4x1) pit system construction |

400Hz Ground Power Cable
In addition to the reference SII construction above, airport projects may call for an open-twisted quadroflex or another flexible construction with central control conductors. These are alternative project configurations, not interchangeable versions of SKU 5025-1; final conductor size, insulation, sheath, current basis, length and certification scope are confirmed in the quotation.| Selection route | Typical construction feature | Quotation check |
|---|---|---|
| Open-twisted quadroflex | Flexible power conductors with a central control-core assembly and abrasion-resistant PUR outer sheath | Confirm phase size, control-core count, maximum route length and voltage-drop basis |
| Integrated sensing-core cable | Power conductors plus separately insulated 4 x 1 mm2 sense/control cores | Confirm aircraft connector contacts, monitoring circuit and required control-wire insulation |
| Long route, reel or bridge system | Project-specific geometry, reinforcement or drum-duty construction | Provide route length, drum core diameter, pull force, speed, cycles and minimum bend radius |
400Hz Ground Power Cable FAQ
Why can route length matter? At 400Hz, conductor size, phase balance, control layout, installation method and allowable voltage drop must be checked together. A reference limit for one open-twisted configuration must not be treated as a universal 15 m limit.Why specify PUR rather than PVC? Where the confirmed construction supports it, PUR can offer stronger abrasion and tear resistance for dragged apron service. The required fuel, oil, UV, temperature and flame performance must be specified rather than assumed from a generic material name.Standards and Test References

Project Documentation for Alternative 400Hz Configurations
Where a project requests CE, UL, flame, halogen, low-smoke or environmental documentation, the quotation must identify the exact ordered construction and applicable certificate or test record. Do not treat a reference standard, an earlier configuration or another cable family as approval for every 400Hz ground power cable.Request a cable recommendation and quotation
