400Hz Drag Chain Power & Control Cable for Passenger Boarding Bridges
400Hz drag chain cable for passenger boarding bridges combines a 0.6/1 kV power-cable module and a matched control-cable module on one system page. It is intended for drag-chain and festoon cable routes where the power and control circuits move with the boarding bridge.

- Power module: 7 × 35 mm², or 7 × 35 mm² + 6 × 6 mm²
- Control module: 12 × 2 × 1.5 mm²
- Movement references: 4 × d fixed, 6 × d flexible, 12 × d continuously flexible; torsion ±60°/1 m

400Hz drag chain cable for passenger boarding bridge systems
This 400Hz drag chain cable is a system-level selection page for the moving cable route on a passenger boarding bridge (PBB). It keeps the power cable and control cable in one documented product family because they share the same moving route, bend path and environmental exposure, while retaining their different conductor arrangements and electrical functions as separate specification modules.
Select the power module for the 400 Hz power circuit: either 7 × 35 mm² or 7 × 35 mm² + 6 × 6 mm². Select the control module for the stated 12 × 2 × 1.5 mm² paired-control arrangement. A 400Hz drag chain cable system should be specified against actual chain geometry, bend radius, torsion, free-hanging length, terminations and circuit separation rather than from conductor area alone.
- Suitable for: stated drag-chain and festoon routes on passenger boarding bridges.
- Power module: moving 400 Hz power distribution.
- Control module: paired control circuits in the same PBB cable-management system.
- Confirm before ordering: route, chain, travel, hanging length, circuits, connector and documents.
A 400Hz drag chain cable quotation should identify the power-module 400Hz drag chain cable and control-module 400Hz drag chain cable separately. This keeps the PBB circuit schedule, cable quantity and termination scope clear before the final 400Hz drag chain cable system is released.
See the airport ground power cable range for related GPU, feeder and reeling-cable families.
400Hz drag chain cable construction
The supplied 400Hz drag chain cable references use bare fine-wire copper conductors with IEC 60228 class 5 cited, halogen-free insulation, layered stranding with non-woven tape, and a yellow halogen-free outer sheath. The power and control modules have different core layouts, so their circuit schedule must be retained in the final design.
| 400Hz drag chain cable construction element | Power module | Control module |
|---|---|---|
| Conductor | Bare fine-wire copper; IEC 60228 class 5 reference | Bare fine-wire copper; IEC 60228 class 5 reference |
| Reference core layout | 7 × 35 mm²; or 7 × 35 mm² + 6 × 6 mm² | 12 × 2 × 1.5 mm² |
| Stranding | Cores twisted in layers; wrapped elements in layers with overlapping non-woven tape | Pairs stranded in layers; wrapped elements in layers with overlapping non-woven tape |
| Outer sheath | Yellow halogen-free sheath, as listed in supplied data | Yellow halogen-free sheath, as listed in supplied data |
Do not treat a power-module 400Hz drag chain cable and a control-module 400Hz drag chain cable as identical replacement parts; verify the circuit function and terminal schedule first.
Passenger boarding bridge drag-chain and festoon applications
This 400Hz drag chain cable family is intended for the stated moving cable routes on passenger boarding bridges: drag chains for guided travel and festoon routes for suspended movement. It is not a fixed feeder cable page and should not be selected for a static route without checking whether the movement construction is needed.
- Power module: use when the PBB cable route carries the specified 400 Hz power conductors.
- Control module: use when the route requires the specified paired control-circuit layout.
- Drag-chain selection: confirm chain inner height, bend radius, travel, separation, support and termination strain relief.
- Festoon selection: confirm free-hanging length, trolley spacing, loop geometry and stated 50 m reference limit.
A power-module 400Hz drag chain cable and a control-module 400Hz drag chain cable can share the PBB system while retaining separate circuit and termination schedules.
Each 400Hz drag chain cable installation must be checked for fixed, flexible or continuously flexible duty. The supplied bend-radius and torsion references are selection inputs, not a substitute for the completed PBB cable-management calculation.
For a cable-drum route rather than a drag-chain route, compare the related 400Hz drum retriever cable.
400Hz drag chain cable specifications
The supplied 400Hz drag chain cable technical data applies to both the power and control modules unless a module row states otherwise. Confirm the selected module and final PBB movement conditions before quotation.

The power-module 400Hz drag chain cable selection depends on the required 35 mm² power circuits and any required 6 mm² auxiliary circuits.
Control module
| 400Hz drag chain cable control configuration | Outer diameter | Copper figure | Approx. cable weight | Maximum ohmic resistance |
|---|---|---|---|---|
| 12 × 2 × 1.5 mm² | Approx. 20.7–22.0 mm | 346 kg/km | 529 kg/km | 1.5 mm²: 13.3 Ω/km |
The control-module 400Hz drag chain cable data is for the supplied paired 1.5 mm² reference configuration.
The power and control modules are separate specification blocks on this 400Hz drag chain cable page because the final PBB system may require different routes, termination methods or cable quantities for each module.
