FAQ

Questions engineers ask first

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

What does the double 'CCW' designation mean in NTSCGECCWÖU?
The first 'C' indicates individual concentric copper screening over each triple-extruded phase core (CGE), while the second 'CW' denotes an overall wave-laid concentric screen and galvanized steel wire armour applied over the inner sheath for heavy mechanical crush and cut protection. 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.
How does NTSCGECCWÖU differ from NTSKCGECWÖU?
NTSCGECCWÖU features dual metallic screens (individual phase screens C plus overall wave armour/screen CW) without the dedicated coal-cutter 'K' control bundle, making it the preferred heavy-duty 3.6/6 kV to 12/20 kV trailing feeder for mobile substations, open-pit excavators, and TBM power lines. 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.
Why are the outer armour wires applied in a wave-form (CW) rather than a straight helix?
A conventional helical steel wire armour locks up or birdcages when a trailing cable is bent repeatedly across uneven mine benches. The sinusoidal wave-laid (CW) wire geometry allows individual armour wires to shift elastically during bending without kinking. 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 voltage classes are available for NTSCGECCWÖU?
We manufacture NTSCGECCWÖU in 3.6/6 kV (Umax 7.2 kV), 6/10 kV (Umax 12 kV), 8.7/15 kV (Umax 17.5 kV), and 12/20 kV (Umax 24 kV) to match standard European and international mine distribution voltages. 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.
