FAQ

Questions engineers ask first

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

What does the letter 'K' signify in NSSHKCGEÖU compared with NSSHCGEÖU?
Under DIN VDE 0250-812, the letter 'K' designates a central profiled semiconductive elastomer cradle (K-cradle) around which the three main phase cores and interstitial control units are cabled. This semiconductive rubber cradle physically separates the phase cores so they cannot crush against one another under rockfall or heavy machine run-over, and ensures immediate phase-to-earth fault detection if internal deformation occurs.
What is the difference between Z-series (free-trailing) and CTE-series (chain-operation) NSSHKCGEÖU?
Z-series NSSHKCGEÖU is built for free-trailing coal shearers, roadheaders, TBMs, and LHD scoops where the cable is dragged directly behind the machine without a protection chain: it incorporates a vulcanized steel strand braid between the inner and outer sheaths with a minimum breaking load of 45 kN, allowing a 40 N/mm² conductor tensile load (up to 36,000 N on 3 × 300 mm²) and travel speeds up to 150 m/min. CTE-series NSSHKCGEÖU is built for cable handler chains that absorb pulling forces: it uses a polyester anti-torsion braid and semiconductive inner sheath to achieve an ultra-tight 2.3 × D minimum bend radius at ≤ 5 N/mm² (5 × D at 15 N/mm²).
How are the pilot (ST) and monitoring (ÜL) cores arranged in the V-series 3 × (2 × 1.5 ST + 1.5 ÜL) construction?
In the V-series pliable steel/copper armoured construction (3 × 25/16 CON to 3 × 120/70 CON), each of the three outer interstices contains a pre-laid control unit made up of two 1.5 mm² EPR-insulated control cores (ST) and one 1.5 mm² semiconductive-screened monitoring core (ÜL/UEL), providing 6 pilot cores and 3 monitoring cores in total across the cable cross-section.
Why does the TEBAOFLEX PDF show 41–46 mm outer diameter for both 3 × 25/16 CON and 3 × 35/16 CON?
In the V-series table on page 2 of datasheet_2c5d8a3975.pdf, the nominal outer diameter bracket for 3 × 25/16 CON and 3 × 35/16 CON is rounded to the same 41–46 mm envelope (with weights of 3,000 and 3,200 kg/km). In precision manufacturer tables (Z-series and CTE-series), 3 × 25 mm² measures 39.2–42.2 mm (Z) / 36–40 mm (CTE) while 3 × 35 mm² measures 40.8–43.8 mm (Z) / 38–42 mm (CTE).
