FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

What is the role of the CW wave-laid concentric screen in NTSKCGECWÖU?
In NTSKCGECWÖU, CW denotes a concentric protective screen whose copper and steel wires are applied in a sinusoidal wave (Wellenform) rather than a rigid helix. When the cable bends sharply in a Bretby drag chain or underground monorail festoon loop, the wave geometry opens and closes elastically without wire buckling or strand breakage.
What does the 'K' element in NTSKCGECWÖU contain?
The 'K' designates an integrated control and pilot-monitoring sub-assembly laid up alongside the three medium-voltage power cores. It carries low-voltage pilot circuits, emergency-stop loops, and shearer telemetry so a single trailing cable powers and controls the longwall coal cutter. Each production drum undergoes routine dielectric voltage testing, conductor DC resistance verification, and sheath dimensional inspection before dispatch with an EN 10204 3.1 mill test certificate.
When should I choose NTSKCGECWÖU versus NTSKCGERLÖU?
Choose NTSKCGECWÖU when the cable runs in overhead underground monorail festoon trolleys or enclosed Bretby cable handlers where lower weight and tight bending flexibility are primary. Choose NTSKCGERLÖU when exposed coal-face dragging demands heavy galvanized steel-strand RL armour against direct rock falls. Each production drum undergoes routine dielectric voltage testing, conductor DC resistance verification, and sheath dimensional inspection before dispatch with an EN 10204 3.1 mill test certificate.
What routine medium-voltage dielectric tests are performed before shipment?
Every production length undergoes a 5-minute AC withstand test at 11 kV rms (for 3.6/6 kV cables) or 17 kV rms (for 6/10 kV cables), partial discharge measurement verifying ≤ 20 pC at 2 U0, and semi-conductive screen resistance verification. Each production drum undergoes routine dielectric voltage testing, conductor DC resistance verification, and sheath dimensional inspection before dispatch with an EN 10204 3.1 mill test certificate.
