global container terminal industry is undergoing its most profound transformation in decades: the electrification of diesel RTG (Rubber-Tired Gantry) cranes into E-RTGs \u2014 machines that draw shore power through a reeling cable instead of burning diesel fuel, achieving up to <strong>95% savings in fuel costs<\/strong> while eliminating local tailpipe emissions <a class=\"src\"

At the heart of every E-RTG electrification system \u2014 whether from Cavotec, Conductix-Wampfler, igus, or VAHLE \u2014 is a single cable that must deliver <strong>both massive three-phase power AND high-bandwidth fiber optic data<\/strong> through a motorised reel that spools thousands of times per year. That cable is the <strong>(N)SHTOEU Trommelflex<span class=\"tm\">\u00ae<\/span> KSM-S FO<\/strong>.<\/p>\n\n <p>With <strong>30 configurations<\/strong> spanning 8 power cross-sections from 3\u00d725 to 3\u00d7240 mm\u00b2 and three fiber optic types (E9\/125 singlemode, G50\/125 multimode, G62.5\/125 multimode) at 12 or 24 fiber counts, the KSM-S FO covers every E-RTG, STS crane, ASC (Automated Stacking Crane), and ARMG (Automated Rail-Mounted Gantry) application in the global container handling industry. Cavotec confirms that their E-RTG solutions are based on cable reel technology with integrated fibre optics critical to terminal operations <a class=\"src\" href=\"https:\/\/www.cavotec.com\/en\/your-applications\/ports-maritime\/crane-electrification\/e-rtg\" target=\"_blank\" rel=\"noopener\">[Cavotec \u2014 E-RTG Solutions]<\/a>.

The KSM-S FO integrates both functions into a single cable, with the fiber optic elements geometrically protected within the cable’s structural interstices.

The protective earth conductors are <strong>split in the outer interstices<\/strong> (as stated in the datasheet) \u2014 distributed symmetrically around the cable to create balanced mechanical geometry. This split-earth design, combined with the fiber optic tubes positioned in the protected inner interstices, creates a geometry where the copper conductors absorb 100% of the radial drum compression force before it reaches the glass fibers <a class=\"src\" href=\"https:\/\/feichuncables.com\/blog\/tratosmart-fo\/\" target=\"_blank\" rel=\"noopener\">[FeiChun \u2014 Interstitial Fiber Isolation Architecture]<\/a>.<\/p>\n\n <p>This crush protection is critical because the primary failure mode of composite reeling cables is not electrical but optical. The copper conductors and EPR insulation can survive millions of reel cycles, but the glass fibers (125 \u03bcm diameter) are exquisitely sensitive to the radial compression that occurs during multi-layer drum winding, where upper cable layers press down on lower layers with forces proportional to cable tension and drum diameter. Without the interstitial protection geometry, fiber attenuation increases progressively with every drum winding cycle until optical signal loss exceeds the link budget \u2014 silently degrading SCADA, video, and safety data communication before any visible cable damage occurs.<\/p>\n\n <\/section>\n\n <!-- ===== S7 ===== -->\n <section class=\"body\" id=\"s7\">\n <h2>The Special Configuration: 3\u00d7120+1\u00d770+(6\u00d72.5)C+FO<\/h2>\n\n <p>Three unique configurations (Part Nos. 054561\u2013054563) add a <strong>screened control bundle (6\u00d72.5)C<\/strong> to the power + FO architecture.

Bare copper provides equivalent electrical performance at lower cost and slightly lower conductor resistance (7.98 \u03a9\/km vs. 8.21 \u03a9\/km for 2.5 mm\u00b2). For applications where the cable will be exposed to marine atmosphere outside the reel enclosure, Feichun can supply tinned copper variants on request.<\/p>\n\n <h3>Can the fiber type be mixed (e.g., 12 SM + 12 MM) within a single cable?<\/h3>\n <p>Yes. The datasheet notes that cables can be manufactured to order or project-specific with E9\/125, 50\/125, or 62.5\/125 fibres or their various combinations. Feichun supports all standard and custom fiber combinations. Contact Feichun’s engineering team for mixed-fiber configurations.<\/p>\n\n <h3>What does “20 N\/mm\u00b2 at the conductor” mean for the Fzp values?<\/h3>\n <p>The Fzp (permanent tensile) = 20 \u00d7 total copper cross-section. For 3\u00d770+2\u00d735\/2 (total copper: 70\u00d73 + 35 = 245 mm\u00b2): Fzp = 20 \u00d7 245 \u2248 4,900 N. The datasheet lists 4,200 N \u2014 slightly conservative. The 20 N\/mm\u00b2 limit represents the stress at which the bare copper conductors begin to yield. This is 33% higher than the 15 N\/mm\u00b2 limit of the standard TROMMELFLEX (K).<\/p>\n\n <h3>Is this cable compatible with Cavotec APS (Automatic Plug-in System)?<\/h3>\n <p>Yes. Cavotec confirms their E-RTG solutions are based on cable reel technology with integrated fibre optics <a class=\"src\" href=\"https:\/\/www.cavotec.com\/en\/your-applications\/ports-maritime\/crane-electrification\/e-rtg\" target=\"_blank\" rel=\"noopener\">[Cavotec \u2014 E-RTG]<\/a>. The KSM-S FO is the standard cable type specified by Cavotec, Conductix-Wampfler, and other E-RTG system integrators. Feichun supplies KSM-S FO equivalents that are dimensionally and electrically compatible with all major E-RTG reel systems.<\/p>\n\n <\/section>\n\n <!-- ===== S12 ===== -->\n <section class=\"refs\" id=\"s12\">\n <h2>References<\/h2>\n <ol class=\"rl\">\n <li>Klaus Faber AG, <em>(N)SHTOEU Trommelflex KSM-S FO \u2014 Product Data Sheet<\/em>, dbl_nshtoeu_ksm_s_fo.pdf, Issue 04\/01\/2026.<\/li>\n <li>Prysmian Group, <em>Low Voltage Reeling Cables for E-RTGs \u2014 TROMMELFLEX KSM-S Technical Data<\/em>. <a href=\"https:\/\/www.prysmian.com\/sites\/default\/files\/business_markets\/markets\/downloads\/datasheets\/Low-Voltage-Reeling-ERTG.pdf\" target=\"_blank\" rel=\"noopener\">prysmian.com<\/a><\/li>\n <li>Cavotec SA, <em>E-RTG Electrification Solutions \u2014 Cable Reel Technology with Fiber Optics<\/em>. <a href=\"https:\/\/www.cavotec.com\/en\/your-applications\/ports-maritime\/crane-electrification\/e-rtg\" target=\"_blank\" rel=\"noopener\">cavotec.com<\/a><\/li>\n <li>VAHLE, <em>Electrification of RTG Cranes \u2014 eRTG Solutions (95% Diesel Savings)<\/em>. <a href=\"https:\/\/www.vahle.com\/fileadmin\/cavok_upload\/Systeml%C3%B6sungen\/eRTG\/Englisch\/Brochure-en-ertg.pdf\" target=\"_blank\" rel=\"noopener\">vahle.com<\/a><\/li>\n <li>igus, <em>e-rover: Cable Management for Electrified RTG Cranes<\/em>. <a href=\"https:\/\/www.igus.com\/cable-carriers\/energy-chains-e-rover-rtg-automatic-coupling-com\" target=\"_blank\" rel=\"noopener\">igus.com<\/a><\/li>\n <li>FeiChun, <em>TRATOSMART\u00ae FO \u2014 Interstitial Fiber Isolation Architecture & Fiber Selection Guide<\/em>. <a href=\"https:\/\/feichuncables.com\/blog\/tratosmart-fo\/\" target=\"_blank\" rel=\"noopener\">feichuncables.com<\/a><\/li>\n <li>FeiChun, <em>NSHTOEU 0.6\/1 kV Drum Reeling Cable \u2014 Complete Technical Analysis<\/em>. <a href=\"https:\/\/feichuncables.com\/blog\/nshtoeu-0-6-1-kv-drum-reeling-cable-alternative-complete-technical-solution-for-sts-rmg-and-rtg-container-cranes-direct-european-equivalent-without-supply-chain-delays\/\" target=\"_blank\" rel=\"noopener\">feichuncables.com<\/a><\/li>\n <li>FeiChun, <em>PROTOMONT Replacement Guide \u2014 3GI3 EPR & 5GM5 Compound<\/em>. <a href=\"https:\/\/feichuncables.com\/blog\/protomont-crane-cable-replacement-complete-technical-guide-prysmian-to-feichun-cross-reference-vde-0250-814-0250-813-compliance-and-reeling-installation-engineering-for-sts-rtg-rmg-a\/\" target=\"_blank\" rel=\"noopener\">feichuncables.com<\/a><\/li>\n <li>Eland Cables, <em>DIN VDE 0250 Standard Cable<\/em>. <a href=\"https:\/\/www.elandcables.com\/electrical-cable-and-accessories\/cables-by-standard\/vde0250-cable\" target=\"_blank\" rel=\"noopener\">elandcables.com<\/a><\/li>\n <li>DIN VDE 0250-814 \/ IEC 60332-1-2 \/ EN 60811-2-1 \/ VDE 0293 (HD308).<\/li>\n <\/ol>\n <\/section>\n\n <div class=\"contact\">\n <h3>Contact Anhui Feichun Special Cable Co., Ltd. \u2014 E-RTG & Composite FO Reeling Cable Specialists<\/h3>\n <div class=\"cg\">\n <div class=\"ci\"><span class=\"lb\">Technical Specifications & Engineering<\/span><a href=\"mailto:Tech@feichuncables.com\">Tech@feichuncables.com<\/a><\/div>\n <div class=\"ci\"><span class=\"lb\">Port & Crane Cable Procurement<\/span><a href=\"mailto:Tech@feichuncables.com\">Tech@feichuncables.com<\/a><\/div>\n <div class=\"ci\"><span class=\"lb\">Emergency Support (24\/7)<\/span>+86 138 5608 5607<\/div>\n <div class=\"ci\"><span class=\"lb\">Technical WhatsApp & WeChat<\/span>+86 138 5512 3218<\/div>\n <\/div>\n <\/div>\n\n <footer class=\"ft\">\n <p>This technical guide is based on Feichun’s proprietary equivalent to the (N)SHTOEU Trommelflex<span class=\"tm\">\u00ae<\/span> KSM-S FO composite power and fiber optic reeling cable, incorporating FC-FLX<span class=\"tm\">\u2122<\/span> Class 5 bare Tongling copper conductors, rubber (EPR) 3GI3 insulation, Gummi 5GM3 inner sheath, rubber (CR) 5GM5 outer sheath, polyester braid torsion protection (\u00b150\u00b0\/m), split protective conductors in outer interstices, and integrated fiber optic elements (E9\/125, G50\/125, G62.5\/125).
