D12YC11Y-J cable is a 0.6/1 kV screened round PUR festoon cable for flexible power and control connections on overhead cranes, trolley systems and material-handling equipment. Its Class 5 copper conductors support frequent bending, while the overall tinned-copper braid helps reduce electromagnetic interference around motors, drives and mixed power/control installations.
The D12YC11Y-J construction combines halogen-free polyester-based core insulation with a black halogen-free, flame-retardant polyurethane outer sheath. The -J suffix identifies a multicore version containing a green/yellow protective conductor. This makes the cable suitable for buyers searching for a screened crane cable, EMC festoon cable or flexible PUR control cable with a protective-earth core.
What Problems Does D12YC11Y-J Cable Solve?
Moving crane systems need more than a flexible conductor. The cable must retain a stable loop shape, tolerate repeated bending and help protect nearby equipment from electromagnetic disturbance. D12YC11Y-J uses a short-lay core arrangement around a central element to support controlled movement in a festoon or guided energy-chain route. In addition, the tinned-copper braid provides an overall electrical screen for installations near variable-frequency drives, motors and control circuits.
The PUR sheath is selected for demanding industrial movement where a conventional static PVC cable would not be appropriate. However, the cable should still be matched to the actual trolley geometry, travel distance, acceleration, support spacing and ambient conditions. It is not a universal torsion cable or an automatic substitute for a vertical or high-speed motorised reeling cable.
Key Features
- Screened 0.6/1 kV construction: for power and control circuits that require an overall tinned-copper braid.
- Frequent-flexing design: Class 5 conductors and short-lay cores support repeated movement in correctly engineered festoon systems.
- Halogen-free PUR sheath: black polyurethane outer protection for demanding indoor and outdoor industrial routes.
- Wide ambient range: reference range of -50°C to +80°C for fixed installation and -40°C to +80°C in fully flexible operation.
- Compact movement geometry: minimum reference bending radius of 6 × overall cable diameter.
- Power and control options: four-core and five-core power constructions plus multicore control versions.

Typical Crane and Material-Handling Applications
D12YC11Y-J screened PUR festoon cable can be specified for overhead travelling cranes, gantry-crane trolleys, warehouse handling equipment, conveyor transfer systems and moving machine tools. The screened construction is especially relevant where the moving route runs close to motors, drives or control equipment and the project requires an overall copper braid.
In a guided energy chain, the chain length, filling ratio, separation, acceleration and minimum bend radius all affect cable life. Therefore, the reference speed must not replace a route calculation. For port or crane installations needing a different construction, review the non-screened PUR-HF festoon cable, the reinforced screened PUR crane cable or the flat PNCT port-crane cable.
D12YC11Y-J vs D12YC11Y-O and D12Y11Y
| Cable type | Overall screen | Protective conductor | Typical selection |
|---|---|---|---|
| D12YC11Y-J | Tinned-copper braid | Green/yellow core included | Screened multicore power or control festoon circuits requiring PE. |
| D12YC11Y-O | Tinned-copper braid | No green/yellow core | Screened circuits where a PE core is not included in that cable. |
| D12Y11Y-J | No overall copper braid | Green/yellow core included | Non-screened festoon applications. |
| (N)12YRDC11Y-J/O | Screened reinforced construction | According to J/O version | Projects needing a different reinforced crane-cable design. |
Application Limits and Installation Notes
- Do not use D12YC11Y-J for continuous axial torsion unless a separately verified torsion-rated design is supplied.
- Do not automatically specify it for vertical reeling or high-speed motorised drums; those routes require a dedicated reeling-cable review.
- Confirm trolley spacing, loop depth, acceleration and the actual minimum bend radius before installation.
- Verify oil, UV, ozone, chemical and water exposure against the final TEBAOFLEX production data sheet rather than relying on the PUR material name alone.
- Ampacity values must be corrected for ambient temperature, grouping and installation conditions.
How to Specify D12YC11Y-J Cable
For an accurate quotation, provide the conductor configuration, cross-section, total length, power or control duty, operating voltage, festoon or chain layout, travel distance, speed, acceleration and environmental conditions. Also state the required cable marking, drum length, termination method and any project-specific flame, oil, UV or water-resistance test.
TEBAOFLEX can review conductor size, core count, sheath colour, production length and marking against the operating route. Final dimensions and electrical data are confirmed with the quotation because moving-cable performance depends on both the cable construction and the mechanical system.
Frequently Asked Questions
What is D12YC11Y-J cable?
It is a 0.6/1 kV screened round PUR cable for flexible power and control connections in festoon and guided moving systems. The cable includes an overall tinned-copper braid and a green/yellow protective conductor.
What does the C mean in D12YC11Y?
In this type designation, C identifies the screened construction. The overall tinned-copper wire braid differentiates it from the non-screened D12Y11Y version.
What is the difference between D12YC11Y-J and D12YC11Y-O?
The -J version includes a green/yellow protective conductor. The -O version does not include a green/yellow conductor.
Can D12YC11Y-J be used in an energy chain?
It can be considered for a properly designed guided chain system. Chain length, filling, bend radius, speed and acceleration must be reviewed, and longer chains may require a lower travel speed.
Is D12YC11Y-J a drum-reeling cable?
Its primary use is in festoon and guided moving systems. Do not substitute it for a vertical or high-speed motorised reeling cable without engineering confirmation.
Can TEBAOFLEX customize the cable?
Core count, conductor size, sheath colour, marking, production length and packaging can be reviewed. Approval scope and performance requirements must be agreed before production.
