FAQ

Questions engineers ask first

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

How is NSSHKCGERLÖU constructed for 1000 V and 3300 V coal-cutter duty?
NSSHKCGERLÖU combines three Class 5 tinned copper power cores insulated with 3GI3 EPR and screened by semi-conductive elastomer plus copper (CGE), an integrated K pilot/control bundle, an inner elastomer sheath, a helical layer of flexible galvanized steel wire strands (RL), and a 5GM5 outer sheath.
Why choose NSSHKCGERLÖU over unarmoured NSHCGEÖU?
Where longwall faces experience heavy roof spalling, scraper-chain pinch hazards, or steep seam gradients, the RL galvanized steel strand armour provides mechanical crush protection and axial tensile reinforcement that unarmoured NSHCGEÖU cannot match. 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.
Is the 1.8/3 kV version compatible with 3.3 kV underground mining switchgear?
Yes. Under DIN VDE 0250-812, the 1.8/3 kV rating carries a maximum system operating voltage Umax of 3.6 kV AC, fully covering standard 3.3 kV underground longwall coal-shearer and roadheader power supplies. 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.
Does the RL steel strand armour restrict use in Bretby cable handlers?
No. Because RL armour is wound from multi-wire fine galvanized steel strands rather than rigid single wires, the cable retains a 10×D dynamic bending radius suitable for standard longwall Bretby cable handling chains. 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.
