Continuous flexing MV cable

15 Min Read
Underground mining is the most electrically hazardous industrial environment on Earth. Mobile machines — coal cutting machines, continuous miners, longwall shearers, load-haul-dump (LHD) vehicles, drill jumbos, raise borers, and shotcrete sprayers — operate in confined, wet, and potentially explosive atmospheres while dragging power cables through tunnels, over rough rock surfaces, around tight corners, and through cable handlers (protection chains) that subject the cable to extreme tensile, crushing, and impact forces. A single insulation failure in this environment can cause electric shock to mine personnel standing in conductive water, or an arcing fault that ignites methane or coal dust.

RHEYFIRM®(RTS) (N)TSCGEWTOEUS

RHEYFIRM®(RTS) (N)TSCGEWTOEUS OFE is a breakthrough composite reeling cable engineered by Anhui Feichun Special Cable Co., Ltd. to meet the DIN VDE 0250-813 German industrial standard. It is the engineering world’s answer to a seemingly impossible challenge: simultaneously carrying massive amounts of high-voltage power (up to 30 kV) and zero-latency, high-bandwidth fiber optic data streams, while being relentlessly spooled onto a motorized drum under extreme mechanical tension and bending stress.

Modern container ports operate Ship-to-Shore (STS) cranes and massive gantry systems that demand unprecedented electrical power delivery. A typical STS trolley requires 18 kV to 30 kV of main power to lift 65-ton containers at speeds exceeding 600 meters per minute. This power must flow through a festoon cable system—a continuous loop of cable that unwinds and rewinds thousands of times per day as the trolley travels back and forth along the boom. Traditional round cables cannot solve this problem efficiently. A round medium voltage cable, rated for 18/30 kV, becomes rigid and difficult to bend. It occupies excessive space in the festoon track, requiring long parking lengths and increasing the footprint of the crane's electrical infrastructure. By contrast, a flat cable lays its massive phase cores side-by-side in a single plane, allowing for an incredibly tight bending radius—sometimes as small as 10 to 15 centimeters—while maintaining full electrical power delivery. This single geometric advantage reduces festoon track length by up to 40 percent, enabling faster crane acceleration and dramatically improving container terminal throughput.

Full technical breakdown Prysmian (Draka) CORDAFLEX SMK series — the "gold standard" for motorized cable reels on portal cranes, stacker-reclaimers, and excavators. Marking (N)TSCGEWÖU, cross-section 3×150+3×25/3, voltage 6/10 kV (max operating 7.2/12 kV). Weight 6.5+ tons/km, OD 58–64 mm, current rating ~425 A (30°C open air), short-circuit ~21.4 kA (1s). Key SMK distinction: built-in anti-torsion guard — reinforced inner sheath with high-strength synthetic braid (aramid/Kevlar) compensating torque from guide rollers and multi-layer winding at speeds up to 120–160 m/min. Without this, standard cables corkscrew and fail on motor drums. Construction: 3×150 mm² tinned copper class 5, split earth 3×(25/3)=3×8.33 mm², EPR insulation type 3GI3, extruded semiconducting screens, polychloroprene (5GM5) or special elastomer outer sheath. Temp -25°C to +80°C standard, Arctic to -40°C. Russian market: GOST КГЭ/КГЭ-ХЛ cables are trailing-only (no anti-torsion) and fail on motor drums. Anhui Feichun offers certified drop-in replacement FC-CORDAFLEX-SMK with integrated aramid anti-torsion braid per VDE, CCV vulcanization, and OD adaptation for existing drums and cable-layers.
