STS (Ship-to-Shore) Quay Crane Main Drum & Spreader Reeling Cable (0.6/1–20 kV)
Complete dynamic reeling and travelling cable solutions (0.6/1 kV to 12/20 kV) engineered for Ship-to-Shore (STS) container quay cranes—covering the medium-voltage main gantry monospiral drum cable (3.6/6 kV, 6/10 kV, 8.7/15 kV and 12/20 kV with integrated optical fibres), the vertical spreader drum/basket cable (0.6/1 kV anti-torsion multi-core) and the high-speed boom trolley festoon system. Manufactured under Jiangsu Tebaoflex Special Cable Co., Ltd.'s ISO 9001:2015 certified reeling cable scope to DIN VDE 0250-813 and DIN VDE 0250-814.
Ship-to-Shore (STS) Super-Post-Panamax container quay cranes rely on three synchronized moving cable systems: the medium-voltage main gantry monospiral drum cable running along the waterside quay rail, the vertical spreader reeling or gravity-basket cable descending from the trolley to the container headblock, and the high-speed boom catenary festoon loop feeding the main trolley.
For the STS main gantry reel (typically 6/10 kV, 8.7/15 kV or 12/20 kV with 5,000–12,000 kVA installed crane load), TEBAOFLEX manufactures R-(N)TSCGEWÖU / (N)TSCGEWOEU electro-optic reeling cables in accordance with DIN VDE 0250-813. Three Class 5 flexible tinned-copper phase cores with triple-extruded semiconductive/EPR insulation are cabled with two split tinned-copper earth cores and a 12- or 24-fibre single-mode (E9/125) or multimode (G50/125) optical subunit inside an aramid-braid-reinforced 5GM5 marine polychloroprene jacket.
For the vertical STS spreader reel and boom festoon, 0.6/1 kV DIN VDE 0250-814 constructions (such as 36G2.5 / 44G2.5 central-aramid spreader cables and 1×120–1×240 mm² or 4G50–4G95 mm² boom festoon cables) withstand hoist speeds up to 180 m/min and trolley speeds up to 240 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 0250-813/-814.
Specify your STS crane subsystem (main MV gantry drum, vertical spreader reel or boom festoon), operating voltage, cross-section and travel length in your RFQ. TEBAOFLEX supplies custom lengths from a 50 m minimum order quantity with a standard lead time of 7–45 working days.

For related automated container yard reeling cables and VDE-standard medium-voltage crane drum constructions, compare: E-RTG & Automated Container Crane (ASC / RMG) High-Speed Reeling Cable (0.6/1–20 kV) (for high-speed ASC, RMG, and E-RTG yard crane reeling up to 20 kV); NTSCGEWOU / (N)TSCGEWÖU+FO Medium Voltage Crane Reeling Cable (for DIN VDE 0250-813 medium-voltage crane drum cables with optional integrated fibre-optic elements). Confirm main drum versus spreader duty, rated system voltage, and maximum travel speed before selection.
