One Festoon System, Multiple Cable Functions
A port crane festoon assembly may carry power, control, signal, paired PG and communication circuits at the same time. These cables move together mechanically, but each circuit requires its own electrical construction and termination review.
TEBAOFLEX can supply the listed 2PNCT-B, 2PNCT-BS and KNPEV-SB configurations as a coordinated project package. The complete cable schedule is reviewed against the crane type, festoon arrangement, trolley dimensions, movement conditions, terminations and required project documentation.
Control and Signal Cables
2PNCT-B 24C × 3.5 mm² and 24C × 2.0 mm² multicore configurations for crane control, auxiliary and signal circuits.
PG and T-Link Cables
2PNCT-BS paired PG cable constructions and a separate KNPEV-SB shielded pair for the T-Link communication route.
2PNCT Festoon Cable Schedule
The following configurations cover the requested power, control, signal, PG and T-Link routes. Final drawings, dimensions, electrical values, cable markings and documentation are confirmed during the project quotation and technical approval process.
| Circuit Function | Cable Type | Configuration | Application Role | Engineering Review |
|---|---|---|---|---|
| Festoon power cable | 2PNCT-B | 3C × 60 mm² | Three-core power supply route for moving crane or material-handling equipment. | Voltage, operating current, conductor arrangement, outside diameter, cable weight, bending radius and termination. |

C indicates individual cores. P indicates conductor pairs. The two designations must not be treated as interchangeable.
Select the Cable by Circuit Duty
The seven enquiry lines belong to the same festoon system but serve different circuit functions. TEBAOFLEX separates the electrical review into four routes while checking the combined mechanical package.
2PNCT-B Power Cable Route
The 3C × 60 mm² and 6C × 22 mm² cables are reviewed against the system voltage, operating current, conductor arrangement, voltage drop, terminal layout and festoon mechanical duty.
2PNCT-B Control Cable Route
The 24C × 3.5 mm² control cable is coordinated with the complete circuit schedule, numbered-core sequence, spare-core requirement, termination space and cable-bundle dimensions.
2PNCT-B Signal Cable Route
The 24C × 2.0 mm² signal cable is reviewed for signal function, conductor identification, required screening, routing separation and compatibility with the crane control cabinet.
2PNCT-BS Paired PG Cable Route
The 8P × 2.0 mm² and 3P × 2.0 mm² constructions are supplied as paired cable routes. Pair numbering, screening, drain-wire and grounding requirements are confirmed from the equipment drawings.
KNPEV-SB T-Link Cable Route
KNPEV-SB 1P × 1.25 mm² is treated as a separate shielded communication cable. Its electrical transmission properties are matched to the specified T-Link controller and route length.
Complete Festoon Bundle Review
The power, control, signal and communication routes are then checked together for trolley loading, cable spacing, loop depth, saddle dimensions and movement conditions.
2PNCT-B, 2PNCT-BS and KNPEV-SB Are Separate Constructions
2PNCT-B Multicore Construction
2PNCT-B configurations are used for the requested festoon power, control and multicore signal routes. The final construction is produced according to the approved conductor arrangement, core identification, reinforcement, sheath and dimensional drawing.
2PNCT-BS Paired Construction
2PNCT-BS is used for the paired PG configurations. The pair layout, screening structure, drain wire and shield termination are confirmed according to the circuit and equipment requirements.
KNPEV-SB Communication Construction
KNPEV-SB is not treated as a 2PNCT power-cable variant. It is a separate shielded pair for communication or instrumentation duty, with electrical requirements matched to the control network.
Core and Pair Identification
A 24-core cable contains 24 individual conductors. An 8-pair cable contains eight conductor pairs. Pair lay and shielding requirements mean that equal conductor counts do not create equivalent cables.
Festoon Geometry Controls the Mechanical Design
Festoon cables are supported in moving loops by cable trolleys. The cable construction must therefore fit the available track, saddle, loop and storage geometry while remaining suitable for repeated bending and movement.
Electrical conductor size alone cannot confirm whether a replacement cable will operate correctly in the existing festoon system. The outside diameter, cable weight, minimum bending radius and complete bundle arrangement must also be checked.
- Crane type and equipment model
- STS, RTG, RMG, gantry, hoist or trolley application
- C-track, I-beam, wire-rope or other festoon support
- Round or flat cable arrangement
- Track length and moving travel distance
- Number and spacing of cable trolleys
- Festoon loop depth
- Trolley saddle width and diameter
- Travel speed and acceleration
- Operating frequency and duty cycle
- Required minimum bending radius
- Total cable-bundle diameter and weight
- Indoor, outdoor, oil, water, UV, salt and abrasion exposure
Common Festoon Cable Replacement Risks
Correct Size, Wrong Construction
A cable can have the requested conductor size but a different reinforcement, screen, sheath, weight or bending behaviour.
Core and Pair Confusion
Multicore control cables and paired signal cables require different conductor layouts, identification and shielding arrangements.
Missing Shield or Drain Wire
Short model descriptions may not identify the complete screen, drain-wire or grounding arrangement required by the original system.
Outside Diameter Mismatch
A larger cable may not fit the trolley saddle, clamp, gland, connector or available festoon storage space.
Incorrect Shield Termination
Screen continuity and grounding must follow the equipment design to maintain the intended signal and communication performance.
Incomplete Cable Schedule
Ordering the power cables separately without checking the control, PG and T-Link routes can create an incompatible combined bundle.
From Cable List to Approved Festoon Package
Submit the Cable Schedule

2PNCT Festoon Cable FAQ
Can TEBAOFLEX supply all seven requested cable configurations?
Yes. TEBAOFLEX can supply the listed 2PNCT-B power, control and signal cables, the 2PNCT-BS paired PG cables, and the KNPEV-SB T-Link cable as a coordinated project package.
Can power, control and signal circuits use the same cable construction?
They may share the same broader cable family, but each route must be configured according to its conductor count, conductor size, screening, identification, termination and electrical function.
What is the difference between 24C and 24P?
A 24C cable contains 24 individual conductors. A 24P cable contains 24 conductor pairs and normally has 48 insulated conductors. Pair construction also introduces different lay, identification and screening requirements.
What is the role of the 2PNCT-BS PG cable?
The requested 2PNCT-BS configurations provide paired circuits for the specified PG, monitoring or signal functions. Pair layout, shielding and grounding are matched to the equipment drawings.
Is KNPEV-SB part of the 2PNCT power-cable family?
No. KNPEV-SB is treated as a separate shielded communication or instrumentation cable. Its transmission requirements are confirmed against the T-Link controller or crane OEM specification.
Can 2PNCT-BS replace KNPEV-SB in a T-Link circuit?
Replacement cannot be confirmed from conductor size alone. Conductor resistance, capacitance, impedance, shielding, route length and controller requirements must also be compatible.
What festoon information is needed before production?
Provide the crane type, track system, travel length, number of trolleys, loop depth, saddle dimensions, travel speed, duty cycle, operating environment and available cable-bundle space.
What should be included in the RFQ?
Send the complete cable schedule, cable lengths, quantities, existing markings, cable or connector photographs, equipment drawings, festoon dimensions, operating conditions and required inspection or test documents.
Send the Complete Festoon Cable Schedule
Include the power, control, signal, PG and T-Link cable lines in one enquiry. Attach the existing cable markings, drawings, cross-section photographs and festoon-system dimensions so the electrical routes and complete moving bundle can be reviewed together.
