What does the French mining designation 1-CBEH stand for?
Under French mining standard NF M 82-375 (Charbonnages de France / AFNOR): '1' = 1 kV rated voltage class (0.6/1 kV); 'C' = flexible copper conductor (Âme cuivre souple Class 5); 'B' = vulcanised ethylene-propylene rubber insulation (EPR); 'E' = collective flexible metallic screen (Écran métallique); and 'H' = heavy-duty oil- and flame-resistant polychloroprene (PCP/CSP) outer sheath.
How does 1-CBEH differ from 1-CHBU?
Both belong to the French NF M 82 underground mining cable family. 1-CBEH incorporates a collective metallic screen ('E') for earth-leakage fault detection on gallery distribution and mobile mining feeders, whereas CHBU (1-CHBU, 3-CHBU, 6-CHBU per NF M 82-376 / 82-377) uses a heavy metallic braid armour ('B' = Blindage/tresse) and heavy polyurethane/neoprene outer jacket ('U') for equipment interconnections across 1 kV, 3 kV and 6 kV.
Why do 1-CBEH power cables include three 2.5 mm² auxiliary cores?
French and West/North African underground mining gate-end boxes use pilot loop supervision, remote start/stop interlocks and earth-continuity monitoring. Integrating 3×2.5 mm² pilot cores inside the screened 1-CBEH assembly allows full gate-end protection through a single flameproof gland.
Is 1-CBEH suitable for damp underground galleries and potash or phosphate mines?
Yes. Tinned Class 5 copper conductors, cross-linked EPR core insulation and the heavy polychloroprene ('H') outer sheath resist saline potash brines, phosphate slurry, diesel mist and mechanical rock abrasion.
