Stacker-Reclaimer & Bucket-Wheel Excavator Drum Reeling Cable (0.6/1–35 kV)
Heavy-duty low- and medium-voltage motorized drum reeling cables (0.6/1 kV, 3.6/6 kV, 6/10 kV, 12/20 kV and 18/30 (36) kV) engineered for rail-mounted bucket-wheel stacker-reclaimers, bucket-wheel excavators, ship loaders and bulk stockyard tripper cars. Manufactured under Jiangsu Tebaoflex Special Cable Co., Ltd.'s ISO 9001:2015 certified production scope for reeling cables (bucket-wheel stacker-reclaimers) to DIN VDE 0250-814 and DIN VDE 0250-813.
Rail-mounted bucket-wheel stacker-reclaimers, bucket-wheel excavators and bulk terminal ship loaders operate over long stockyard runways (often 400 m to 1,500 m) with monospiral or cylindrical motorized cable reels under constant tensile load, abrasive coal/iron-ore dust and severe weather. TEBAOFLEX manufactures both low-voltage (0.6/1 kV) and medium-voltage (3.6/6 kV up to 18/30 kV, Umax 36 kV) drum reeling cables specifically engineered for stacker-reclaimer service.
Jiangsu Tebaoflex Special Cable Co., Ltd. holds valid ISO 9001:2015 quality management certification (certificate no. 244-24-QI-17425-R0-Q, valid through 2027-12-17) whose certified production scope explicitly covers reeling cables for bucket-wheel stacker-reclaimers and shore-to-ship power connections, supported by third-party verification of conformity (ICR, cert. ICR/VC/HTT260331) against DIN VDE 0250-813 and DIN VDE 0250-814.
Low-voltage 0.6/1 kV stacker-reclaimer reeling cables follow DIN VDE 0250-814 ((N)SHTÖU-J / SMK) with Class 5 tinned copper conductors, +90 °C EPR insulation, anti-torsion aramid/synthetic braid and a double-sheathed polychloroprene (PCP / 5GM5) outer jacket. Medium-voltage 3.6/6–18/30 kV feeder reeling cables follow DIN VDE 0250-813 ((N)TSCGEWÖU / R-(N)TSCGEWOEU) with triple-extruded semiconductive/EPR dielectric, split interstitial earth conductors (3+3) and optional integrated optical fibres.
Share your stacker-reclaimer operating voltage, main transformer kVA or motor current, runway travel length, center-feed vs. end-feed reel geometry and drum barrel diameter with your enquiry. TEBAOFLEX supplies custom continuous drum lengths from a 50 m minimum order quantity with a standard lead time of 7–45 working days.

For related stockyard, open-pit excavator, and bulk terminal drum reeling constructions, compare these specifications: R-(N)TSCGEWÖU Medium Voltage Reeling Cable 3.6/6–18/30 kV (for VDE-designated EPR/PCP medium-voltage excavator and yard drum reeling from 3.6/6 to 18/30 kV); Grab Bucket & Bulk Handling Crane Heavy-Duty Drum Reeling Cable (0.6/1–6/10 kV) (for cyclic bulk terminal grab crane and ship-unloader drum service up to 6/10 kV). Verify travel length, anti-torsion braid geometry, and rated voltage before specifying.
Construction
The representative construction illustrates 6/10 kV R-(N)TSCGEWÖU 3×70 + 3×35/3 mm² Stacker-Reclaimer Drum Reeling Cable: three Class 5 flexible tinned-copper phase conductors with inner semiconductive screen, +90 °C EPR insulation and outer semiconductive elastomer screen, laid up in trefoil with three split bare tinned-copper earth conductors in the interstitial valleys, encased in a light-grey elastomeric inner sheath, anti-torsion reinforcing braid and a black heavy-duty 5GM5 polychloroprene rubber outer sheath.
| Component | Material and construction |
|---|---|
| Phase conductors | Class 5 extra-flexible rope-lay stranded tinned copper conductors per DIN EN 60228 / VDE 0295 (16 mm² to 240 mm² for 0.6/1 kV; 25 mm² to 185 mm² for 3.6/6–18/30 kV). |
| Insulation & dielectric screening | 0.6/1 kV: +90 °C 3GI3 ethylene-propylene rubber (EPR). 3.6/6–18/30 kV: triple-extruded inner semiconductive layer, +90 °C EPR medium-voltage dielectric and outer semiconductive elastomer screen. |
| Protective earth conductors | 0.6/1 kV: fourth green/yellow core or 3+3 split earth. 3.6/6–18/30 kV: three symmetrically split tinned-copper earth conductors laid in the interstitial valleys. |
| Inner sheath / bedding | Vulcanized light-grey 5GM3/5GM5 elastomeric inner sheath filling all core interstices to lock the core lay pitch against corkscrewing under monospiral reel tension. |
| Anti-torsion reinforcing braid | High-tenacity aramid or polyester anti-torsion open-weave braid vulcanized between the inner and outer sheaths (permissible tensile load up to 20–30 N/mm² of copper cross-section). |
| Outer sheath | Heavy-duty black polychloroprene rubber (5GM5) or polyurethane (11YM1) outer jacket resistant to coal dust, iron-ore abrasion, UV, ozone, oil and -40 °C cold flexing. |
Applications
Select 0.6/1 kV (N)SHTÖU-SMK for low-voltage yard stackers and auxiliary reels, or 3.6/6 kV to 18/30 kV R-(N)TSCGEWÖU for high-capacity bucket-wheel stacker-reclaimers and open-cast bucket-wheel excavators.
- Coal, iron-ore, bauxite and potash terminal rail-mounted bucket-wheel stacker-reclaimers with monospiral or wide cylindrical cable reels.
- Power plant stockyard stackers, bridge-type scraper reclaimers and belt-conveyor tripper cars.
- Open-pit lignite and overburden bucket-wheel excavators (BWE) and mobile belt wagons operating down to -40 °C.
- Bulk port ship loaders and continuous barge unloaders requiring high-tensile dynamic reeling up to 120 m/min.
For rail-mounted yard travel, open-pit lignite excavator reeling, and night-shift trailing routes, examine these references: Bucket-Wheel Excavator Reeling Cable for a Polish Mine (for 12/20 kV lignite mine excavator drum engineering and field execution); (N)TSCGEH3S Cable 3.6/6 kV and 6/10 kV Luminescent Mining Trailing Cable (for high-visibility luminescent open-pit mining trailing and reeling circuits at 3.6/6 kV and 6/10 kV). Check drum barrel diameter, travel speed, and guide-roller radii before installation.
