(N)TSCGECECWÖU 8.7/15kV 12/20kV TBM Reeling Cable

(N)TSCGECECWÖU 8.7/15kV 12/20kV TBM Reeling Cable is a TEBAOFLEX cable for the application and operating conditions identified in the original product record. Voltage drop depends on conductor size and power factor. At power factor 0.8, typical voltage drop values are 1.45V/A/km for 25mm², 1.06V/A/km for 35mm², 0.77V/A/km for 50mm², 0.56V/A/km for 70mm², 0.45V/A/km for 95mm² and 0.36V/A/km for 120mm². Current capacity should also be corrected for ambient temperature. At 40°C the de-rating factor is 0.91; at 50°C it is 0.82; at 60°C it is 0.71; and at 80°C it is 0.41. For TBM reeling systems, cable selection should consider more than rated voltage. Buyers should check drum diameter, number of reeled layers, travel route, bending radius, torsion, ambient temperature, current load, voltage drop and available installation space. The same conductor size can carry different current depending on whether it is laid on the floor or reeled in multiple layers, so project quotations should include both the electrical load and the reeling arrangement. (N)TSCGECECWÖU Cable is a medium voltage reeling cable for tunnel boring machines and tunnel power applications. The source record places this product in mining & tunneling cables. Before ordering, confirm the exact product variant, conductor or core arrangement, system rating, route conditions, equipment connection and required documentation against the project specification.

4. Protective earth conductor: Individual copper wire screen.
5. Control conductor: Class 5 tinned copper conductor.
6. Central filler: Semiconductive compound on a textile polyester support.
7. Inner sheath: Rubber compound.
8. Monitoring conductor: Copper wire screen over the inner sheath.
9. Outer sheath: Red rubber compound.

(N)TSCGECECWÖU 8.7/15kV 12/20kV TBM Reeling Cable applications

Applications

• Reeling drum power supply for tunnel boring machines.
• Medium voltage flexible cable routes in tunnel construction.
• Indoor and outdoor tunnel applications requiring red rubber-sheathed medium voltage cable.
• Mobile power supply where bending radius, torsional stress, tensile load and cable weight must be checked before installation.
• Project designs that require protective earth, control conductor and monitoring conductor functions in one cable construction.

Selection Notes for Buyers

For TBM reeling systems, cable selection should consider more than rated voltage. Buyers should check drum diameter, number of reeled layers, travel route, bending radius, torsion, ambient temperature, current load, voltage drop and available installation space. The same conductor size can carry different current depending on whether it is laid on the floor or reeled in multiple layers, so project quotations should include both the electrical load and the reeling arrangement.

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.

Voltage Drop and De-Rating Notes

Voltage drop depends on conductor size and power factor. At power factor 0.8, typical voltage drop values are 1.45V/A/km for 25mm², 1.06V/A/km for 35mm², 0.77V/A/km for 50mm², 0.56V/A/km for 70mm², 0.45V/A/km for 95mm² and 0.36V/A/km for 120mm². Current capacity should also be corrected for ambient temperature. At 40°C the de-rating factor is 0.91; at 50°C it is 0.82; at 60°C it is 0.71; and at 80°C it is 0.41.
