FAQ

Questions engineers ask first

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

What do the designations GE, KON, ST, and ÜL signify in NSHCGEÖU KON+ST+ÜL?
GE denotes the semi-conductive elastomeric screen layer (leitfähige Gummischicht), KON designates the overall concentric protective earth conductor (konzentrischer Schutzleiter), ST indicates the integrated control cores (Steuerleiter), and ÜL is the insulated pilot monitoring conductor (Überwachungsleiter) used with underground gate-end pilot relays. 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 the concentric KON+ÜL screen protect underground mining personnel?
Any conductive foreign object—such as a roof bolt, scaling bar, or crushed rock—penetrating the outer 5GM5 jacket contacts the grounded concentric KON/ÜL screen and semi-conductive GE elastomer before reaching a live phase core, instantaneously tripping the gate-end earth-fault/pilot circuit breaker. 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 NSHCGEÖU KON+ST+ÜL differ from standard NSSHÖU?
Standard NSSHÖU is an unscreened heavy-duty rubber cable, whereas NSHCGEÖU KON+ST+ÜL adds a semi-conductive elastomeric fault-detection layer (GE), a concentric copper screen (KON), pilot monitoring (ÜL), and dedicated control cores (ST) for monitored underground coal and potash face machinery. 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.
Can NSHCGEÖU KON+ST+ÜL be supplied for 1.8/3 kV coal-face voltage systems?
Yes. In addition to the standard 0.6/1 kV rating, we manufacture NSHCGEÖU KON+ST+ÜL with increased 3GI3 EPR wall thickness for 1.8/3 kV (Umax 3.6 kV) underground longwall and roadheader distribution networks. 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.
