FAQ

Questions engineers ask first

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

What do each of the letters in the VDE designation 'NSGAFCMÖU' stand for?
N = standard type to DIN VDE 0250; SGA = special rubber-insulated single-core wire (Sonder-Gummi-Aderleitung); F = fine-stranded flexible conductor (Class 5); C = concentric copper screen; M = elastomer outer sheath (Mantel); Ö = oil-resistant (Ölbeständig); U = flame-retardant (Flammwidrig).
Why is NSGAFCMÖU specified instead of unscreened NSGAFÖU / CGAU in underground mines and rail traction?
In underground mining switchgear (DIN VDE 0118) and rail traction converters, any mechanical crushing or insulation fault on a phase wire must be intercepted by a grounded metallic screen before it can arc to an adjacent phase or energise an enclosure. The concentric copper screen (`CM`) guarantees that any fault is immediately converted into a monitored earth fault, while also providing 360° EMC shielding for PWM inverters.
Can the concentric copper screen (`CM`) be used as the protective earth (PE) conductor?
The concentric copper screen is dimensioned (from 1.5 mm² up to 35 mm²) to carry earth-fault currents and trip protective relays, or to serve as the EMC shield. Whether it may serve as the sole PE conductor depends on the prospective fault current I²t of your circuit breaker per DIN VDE 0100-540.
What is the maximum operating voltage of a 1.8/3 kV NSGAFCMÖU cable in AC and DC systems?
Under DIN VDE 0250-602, the cable is rated U0/U = 1.8/3 kV with a maximum three-phase AC system voltage Um = 3.6 kV AC and a maximum DC operating voltage of 2.7/5.4 kV DC.
