TROMMELFLEX KSM-S & (N)SHTOEU-SMK Spring & Motorized Drum Reeling Cable (0.6/1 kV)

Spring-driven cable reels and motorized monospiral or cylindrical cable drums subject their feeder cables to simultaneous axial tension, S-bend roller deflection and torsional twisting. TROMMELFLEX KSM-S, TROMMELFLEX PUR-HF and (N)SHTOEU-SMK (also written (N)SHTÖU-SMK) 0.6/1 kV drum reeling cables are engineered to DIN VDE 0250-814 to eliminate core corkscrewing and jacket delamination under continuous reversing reel duty.

In the classic (N)SHTOEU-SMK construction, Class 5 flexible tinned or bare copper conductors are insulated with +90 °C 3GI3 ethylene-propylene rubber (EPR) and cabled in a short lay pitch around a high-tenacity aramid/synthetic center cord. A pressure-extruded 5GM3 elastomeric inner sheath fills every interstice, while an open-weave aramid anti-torsion braid vulcanized beneath the black 5GM5 polychloroprene outer sheath locks the inner and outer jackets into a single torque-balanced tube.

For compact high-speed spring reels and multi-core control drums (up to 42G1.5 or 24G2.5), the TROMMELFLEX KSM-S and TROMMELFLEX PUR-HF variants utilize thin-wall high-modulus core insulation and either a tear-resistant 5GM5 rubber jacket or a halogen-free 11YM1 polyurethane jacket rated for travel speeds up to 180 m/min. Jiangsu Tebaoflex Special Cable Co., Ltd. holds ISO 9001:2015 certification (cert. 244-24-QI-17425-R0-Q) covering reeling cable production and third-party verification of conformity (ICR, cert. ICR/VC/HTT260331) against DIN VDE 0250-814.

Specify the series (KSM-S, PUR-HF or (N)SHTOEU-SMK), core count and cross-section, spring vs. motorized drum diameter and required length in your enquiry. TEBAOFLEX supplies custom drum lengths from a 50 m minimum order quantity with a standard lead time of 7–45 working days.

For related VDE-standard rubber drum reeling cables in crane and hoisting duty, compare these specifications: NSHTOU / (N)SHTÖU 0.6/1 kV Low Voltage Reeling Cable (for standard DIN VDE 0250-814 heavy-duty polychloroprene drum reeling at 0.6/1 kV); NSHTÖU-J Rubber Reeling Cable 0.6/1 kV for Hoisting and Hauling Equipment (for multi-core hoisting, gantry, and material-handling drum feeders at 0.6/1 kV). Verify central aramid or textile support core, anti-torsion braid, and spring-drum torque before ordering.

Construction

The representative construction illustrates (N)SHTOEU-SMK 0.6/1 kV 4G50 mm² Heavy-Duty Drum Reeling Cable: four Class 5 flexible copper cores (blue, brown, black and green/yellow) insulated with +90 °C 3GI3 EPR and cabled around a central aramid tension cord, encased in a vulcanized light-grey elastomeric inner sheath, a wide-mesh high-tenacity aramid anti-torsion braid and a black 5GM5 flame- and oil-resistant polychloroprene outer sheath.

Applications

Choose (N)SHTOEU-SMK for heavy power and harsh outdoor crane/hoist drums, or TROMMELFLEX KSM-S / PUR-HF for compact spring reels and multi-core control/bus drums.

• Industrial spring-operated cable reels on workshop gantry cranes, portal cranes, transfer cars and telescopic spreader beams.
• Motorized monospiral and wide cylindrical cable drums on shipyard cranes, timber yard gantries, sewage treatment bridges and bulk hoppers.
• Construction hoists, concrete batching plants and tunneling gantry reels exposed to mud, mineral oil, sharp aggregate and frequent directional reversals.
• Combined power (4G/5G) and multi-core control (7G to 42G) reeling runs operating at travel speeds up to 120–180 m/min.

For magnet cranes, portal cranes, transfer cars, and directional guide-roller reels, explore these solutions: Reeling Cable Solutions for Cranes and Mobile Equipment (for low- and medium-voltage drum cable sizing and installation geometry); (N)12YRD11Y-J/O & (N)12YRDC11Y-J/O 0.6/1 kV High-Tensile PUR Reeling Cable (for cut-resistant 0.6/1 kV polyurethane outer sheath drum reeling). Confirm S-bend roller spacing, travel speed, and maximum pulling force for your reel.

Specifications

These are the standards this construction is designed and manufactured to (DIN VDE 0250-814 and DIN VDE 0298-4).

Continuous current ratings are based on +30 °C ambient air in free air; apply DIN VDE 0298-4 drum-layer derating factors (0.80 for 1 layer, 0.61 for 2 layers, 0.49 for 3 layers, 0.42 for 4 layers).

Third-party verification of conformity (ICR, cert. ICR/VC/HTT260331) against DIN VDE 0250-814 is based on test reports XMT0202600330W/EMC and /LVD (Shanghai Ximo Testing Technology, 2025-03-30).
