400Hz Aircraft Ground Power Cable for Airport GPU Systems

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. The supplied product set also includes a 4 x 95 mm2 reference image. Confirm whether that size, the 4 x 70 mm2 construction, or another conductor size is required for the project before production.

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.

• Aircraft 400Hz ground power supply systems and GPU cable assemblies
• Mobile ground power units and airport ground support equipment
• Passenger boarding bridge and grounded-pit power routes
• Apron, hangar and MRO aircraft power connection systems
• Cable harnesses or connector-ready assemblies for GSE projects

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.

• 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.

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. The rated voltage, test voltages, current rating, conductor resistance, bending radius and weight in the first table belong to the SII reference construction; for this construction they are confirmed in the written quotation for each order.

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.

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

The following references are carried over from the supplied product data for this construction. They describe the stated conductor, material or test basis; the documentation and marking scope for the ordered size should be confirmed with the quotation. Request the applicable routine test report, inspection release, marking record or connector documentation when those items are required by the project.

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.
