400Hz Ground Power Cable for GPU Cable Reels

400Hz ground power cable for motorized airport cable reels

This 400Hz ground power cable is designed for motorized and spring-driven cable reels in 400Hz Fixed Electrical Ground Power (FEGP) systems, supplying parked aircraft on busy airport aprons. An aramid-reinforced inner structure and a PUR double sheath let the cable take repeated reel cycles without structural fatigue, and the compounds are selected for cold flexibility on exposed aprons.

The construction is customized to the project: power-core cross-section, control-core count, outer diameter, weight and current rating are confirmed in the technical offer rather than taken from a fixed catalogue size. Larger variants such as 3 × 70 mm² power cores are available.

Before ordering, confirm the conductor or core arrangement, system rating, reel core diameter, route conditions, equipment connection and required documentation against the project specification. See the airport ground power cable range for related 400Hz and 28 V DC constructions.

A different 400 Hz construction, four separately sheathed 1×70+4×1 cores twisted together for a Russian buyer's civil-airport pit system, is described on the 400 Hz pit system ground power cable case page, with the buyer's questions on cut length and PUR at −40 °C.

400Hz ground power cable construction for reels

Three symmetrically laid power cores with three smaller conductors and grouped control cores laid in the interstices, an aramid supporting screen and a PUR double sheath. Core sizes, control-core count, sheath colour and marking are customized and confirmed against the ordered cable schedule.

400Hz ground power cable reel applications

Typical Installation Scenarios

• Motorized Cable Reel Systems (PIT-in-Ground): The primary application. The cable is wound onto motorized drums recessed into the apron surface. The symmetrical three-core geometry handles the continuous load cycling without core fatigue.
• Spring-Driven Overhead Reel Systems: Mounted on elevated structures at gates or hangars. The aramid support screen prevents core elongation under the tension loading of spring retraction.
• Passenger Boarding Bridge (PBB) Power Reels: Serves as the dynamic reel cable between the fixed power source and the bridge-mounted connector, handling repeated extension cycles as each aircraft docks.
• Scissor-Lift Cable Management: Highly compatible with scissor-lift cable carrier systems used in specific airport pier configurations.

Selection checks

Confirm the equipment interface, installation method, route length, movement or flexing duty, environmental exposure, conductor or core requirements and project documentation before final selection.

Electrical basis, bending rules and materials are listed below. Dimensions, resistance, temperature class and current rating are customized per project and confirmed with the quotation.

Technical Specifications

400Hz ground power cable standards and compliance

The following standard references identify the material basis and do not replace project-specific certification or inspection requirements.

• Halogen-Free for Enclosed Environments: Compliant with IEC 60754-1 safety standards, the halogen-free construction ensures that in the event of a fire, the cable does not release toxic halogen gases—a critical safety requirement for underground equipment rooms and passenger boarding bridges (PBBs).
• Current rating: customized per project and calculated for the actual reel installation and duty cycle.
• Safety Compliance Halogen-Free (IEC 60754-1), Oil Resistant (EN 50363-10-2), RoHS

Where a project requires a test report, certificate, marking record or inspection release, include that requirement in the quotation request.
