1
Extra-flexible Class FS tinned copper conductor
Very finely stranded tin-plated electrolytic copper, Class FS / Class 5 per DIN VDE 0295 / IEC 60228Three (or 3+3) main phase cores (6–240 mm²) plus extensible copper/steel pilot (ST) and monitoring (ÜL) conductors
2
Core insulation (3GI3 EPR)
Heat-resistant cross-linked ethylene-propylene elastomer (EPR) compound type 3GI3DIN VDE 0207-20 · main cores black, grey, brown; control cores blue (rated +90 °C / +250 °C short-circuit)
3
Cold-strippable semiconductive screen (E)
Easy-strip outer semiconductive rubber layer extruded over each phase core insulation (plus semiconductive tape)Confines electric field and provides phase-to-earth fault detection across all power cores
4
Interstitial pilot, earth & monitoring elements (STKON / ÜLKON)
Three double-concentric control/PE wire spinnings (1.5STKON + 16/3KON to 120/3KON) or 2ST+ÜL in outer interstices (plus central aramid support on S-series)Provides continuous earth-loop monitoring, pilot interlock, and symmetrical core bed
5
Inner sheath (GM1b vulcanized EPR)
Vulcanized EPR rubber inner sheath compound type GM1bDIN VDE 0207-21 · locks core lay geometry under tight 2.3 × D chain bending
6
Concentric earth / monitoring spinning or torsion braid (C)
Helical spinning of tinned copper and galvanized steel wires vulcanized between inner and outer sheath (or polyester anti-torsion braid on S-series)Acts as overall concentric earth/monitoring armour and prevents sheath shift
Typical values for this cable type; dimensions and weights for your order are confirmed in the quotation.
In V-series chain-handler coal cutter cables, minimum bending radius r_min = 2.3 × D_max applies in cable protection chains where tensile stress on the conductor does not exceed 5 N/mm² (maximum permissible pull = 15 N/mm²).
In S-series underground reeling cables (with central aramid yarn support element and vulcanized polyester anti-torsion braid), permissible tensile load is 30 N/mm² (up to 10,800 N on 3 × 120 mm²) with r_min = 4 × D_max and travel speed up to 160 m/min.
Six-core (3+3) coal cutter cables split the phase load across six power cores (two parallel 3-phase circuits) to keep overall diameter compact in high-power longwall shearer chains.

What do the letters C, G, E, ST, ÜL (UEL), and KON mean in NSSHCGEÖU?
Under DIN VDE 0250-812, 'NSSH...ÖU' denotes a heavy-duty oil-resistant mining rubber cable (parentheses around N indicate a construction adapted to VDE 0250-812, such as 6-core or central-aramid reeling designs). 'C' denotes a concentric copper/steel wire screen or monitoring layer; 'G' denotes 3GI3 EPR rubber insulation; and 'E' denotes individual core screening with a cold-strippable semiconductive elastomer layer. In the core callout, 'ST' designates extensible pilot/control cores, 'ÜL' (or 'UEL') designates the earth-continuity/insulation monitoring conductor, and 'KON' designates a concentric copper wire spinning over the control cores or under the outer sheath.
When should V-series chain-handler NSSHCGEÖU be chosen versus S-series reeling (N)SSHCGEÖU?
V-series NSSHCGEÖU is engineered for longwall coal cutters (shearers) where the cable is guided inside a trailed cable protection chain (cable handler) that absorbs pulling forces; it allows an ultra-tight minimum bend radius of 2.3 × D (at ≤ 5 N/mm² conductor tension, max 15 N/mm²) and includes a concentric copper/steel monitoring screen between the inner and outer sheaths. S-series (N)SSHCGEÖU adds a central aramid yarn support element and a vulcanized polyester anti-torsion braid to double the permissible tensile stress to 30 N/mm² and allow motorized reeling up to 160 m/min on underground LHD loaders and scooptrams.
Why does the attached TEBAOFLEX PDF only show 3 × 6/6 CON + 2 × 1.5 ST + 1.5 UEL while the page lists 3 × 25 to 3 × 150 mm²?
The attached PDF (datasheet_168a58e586.pdf) was generated specifically for the 3 × 6/6 CON + 2 × 1.5 ST + 1.5 UEL screened mine and tunnel lighting configuration ((N)SSHCGEWÖU), whereas the product page covers the full NSSHCGEÖU / (N)SSHCGEÖU coal cutter and underground reeling family. Both the 3 × 6/6 CON lighting build and the full 3 × 16 to 3 × 240 mm² and (3+3) × 50 to (3+3) × 120 mm² coal cutter and LHD reeling ranges are included in the specification table above.
When should NSSHKCGEÖU (with 'K') be specified instead of NSSHCGEÖU?
Specify NSSHKCGEÖU when the cable requires a central semiconductive rubber profile cradle ('K') that physically separates the main phase cores against extreme crushing forces, or when the coal cutter operates in free-trailing mode without a protection chain and requires a 45 kN steel wire braid armour (40 N/mm² tensile load).
