FAQ

Questions engineers ask first

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

What does the French mining designation 6-CHCU TTAR mean?
Under NF M 82-375, '6' indicates the 0.6/1 kV (up to 1.1 kV mining) voltage class; 'C' and 'H' denote elastomeric EPR core insulation and a heavy-duty chloroprene/CSM outer sheath; 'CU' specifies Class 5 flexible copper conductors; 'TT' stands for Tout-Terrain (all-terrain impact and cut protection); and 'AR' denotes Anti-Rotation (the high-tenacity anti-torsion braid vulcanised between the inner and outer sheaths).
When should I specify 6-CHCU TTAR instead of standard 6-CHCU-TT?
Choose 6-CHCU TTAR whenever the cable is wound under high dynamic tension on monospiral or cylindrical reels, routed through multi-plane diversion rollers, or subjected to combined twisting and roadway dragging on electro-hydraulic drill jumbos and LHD scooptrams. The AR anti-torsion braid locks the inner and outer sheaths together against corkscrewing up to ±100 °/m and 20–25 N/mm² tensile pull.
Can 6-CHCU TTAR be supplied with pilot cores for ground-check and remote control?
Yes. Alongside standard 4-core (3 × phase + 1 × earth) power sizes from 3 × 16 + 16 up to 3 × 150 + 70 mm², 6-CHCU TTAR is supplied with one to three 2.5 mm² or 4 mm² extensible pilot cores laid up in the core interstices for gate-end box earth-continuity interlock and remote control.
What bending radius and drum derating apply on underground jumbo reels?
Maintain at least 6 × OD for free trailing loops and 8 × OD for forced drum reeling (drum barrel diameter ≥ 16 × OD). When wound in multiple layers on a jumbo or loader reel, apply DIN VDE 0298-4 layer derating factors to the 30 °C free-air current ratings to keep the 3GI3 EPR insulation within its +90 °C conductor limit.
