FAQ

Questions engineers ask first

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

What is the difference between NTSKCGWÖU and NTSKCGWÖU KON for underground loaders?

Standard NTSKCGWÖU places three split protective earth conductors in the outer core interstices around a central extensible pilot core (ST). NTSKCGWÖU KON replaces the split interstitial earths with a concentric tinned-copper and synthetic-yarn earth screen applied around the core bundle, reducing overall cable diameter so longer lengths fit onto compact LHD scooptram reels.

Why does an LHD loader cable need a central extensible pilot core (ST)?

During underground mucking and tramming, the loader reel subjects the cable to repeated acceleration peaks of 25–30 N/mm² and tight S-bends around guide rollers. Placing an extensible tinned-copper pilot core on the neutral central axis prevents premature pilot wire breakage and maintains continuous ground-check loop monitoring back to the gate-end box.

How is the electric field controlled at 3.6/6 kV and 6/10 kV?

Each phase core uses a triple-extruded dielectric: an inner semi-conductive EPR layer over the Class 5 tinned copper conductor, 3GI3 ethylene-propylene rubber insulation, and a cold-strippable outer semi-conductive NBR/EPR screen (resistivity ≤ 200 Ω·m) in continuous contact with the split interstitial earths or KON concentric earth screen.

What drum diameter and current derating apply on cylindrical LHD reels?

Maintain a minimum forced-reeling bending radius of 12 × OD (drum barrel diameter ≥ 24 × OD) and 10 × OD on free-moving loops. Because LHD cables wind in multiple layers on cylindrical drums, apply DIN VDE 0298-4 layer reduction factors (typically 0.76 for one layer, 0.61 for two layers, and 0.49 for three wound layers).
