Full technical breakdown of Nexans (Rheydt) RHEYFIRM®(SI) NTMCGCWOEUS series — the benchmark flexible single-core medium voltage cable for movable connections between circuit breakers and mobile transformers at open-pit mines, underground mines, and industrial power installations. VDE marking NTMCGCWOEUS, voltages 6/10 kV and 12/20 kV, cross-sections 16–240 mm². Conductor: flexible tinned copper class 5 per IEC 60228. Insulation: proprietary RHEYCLEAN compound based on EPDM, exceeding DIN VDE 0207-20. Outer semiconducting screen RHEYSTRIP with easy-strip design. Screen: close-spinning tinned copper wires/strands. Outer sheath: heavy-duty abrasion & notch-resistant rubber compound 5GM5 per DIN VDE 0207-21, red colour. Max conductor temp +90°C (service) / +200°C (short circuit). OD 20–45 mm. Weight 690–3,660 kg/km. Oil, UV, ozone, moisture resistant. Flame retardant IEC 60332-1. Indoor/outdoor. Standards: DIN VDE 0250-813, DIN VDE 0298, DIN VDE 0298-4. Anhui Feichun offers certified drop-in replacement FC-RHEYFIRM with identical layer construction, EPDM insulation, copper screen, and 5GM5 sheath per VDE — import substitution for Russian mines, energy, and industry.
