The <strong>NSHTOEu \/3<\/strong> defies this convention. It is explicitly rated for <strong>five distinct dynamic application modes<\/strong>: reeling operation, festoon systems, drag chain installations, multi-roller guidance, and free movement \u2014 each with its own application-specific bending radius requirement published directly on the Klaus Faber datasheet. This multi-application versatility, combined with <strong>resistance to acids, lyes, and oils<\/strong> (a chemical resistance profile unique among reeling cables), makes the NSHTOEu \/3 the most versatile heavy-duty rubber reeling cable available in the DIN VDE 0250-814 product family.<\/p>\n\n    <p>The NSHTOEu \/3 carries an additional distinction that premium CORDAFLEX variants do not: <strong>dual tensile ratings<\/strong>. Every configuration lists both <strong>Fzp (permanent tensile)<\/strong> and <strong>Fzd (dynamic tensile)<\/strong> values, giving cable specification engineers explicit data for both sustained-load and dynamic-load calculations. For the largest configuration (3\u00d7240+3\u00d7120\/3), Fzp = 10,800 N and Fzd = 14,400 N \u2014 a 33% increase in permissible tensile under dynamic conditions, reflecting the cable&#8217;s ability to handle the transient peak loads that occur during rapid acceleration, deceleration, and direction-reversal in crane reeling operations.<\/p>\n\n  <\/section>\n\n  <!-- ===== S2 ===== -->\n  <section class=\"body\" id=\"s2\">\n    <h2>Full Technical Specification<\/h2>\n\n    <div class=\"tw\">\n      <table>\n        <caption>NSHTOEu \/3 \u2014 Complete Specifications (per Klaus Faber Datasheet dbl_nshtou3.pdf, Issue 04\/02\/2026)<\/caption>\n        <thead><tr><th>Parameter<\/th><th>Specification<\/th><th>Engineering Significance<\/th><\/tr><\/thead>\n        <tbody>\n          <tr><td>Standard<\/td><td><strong>VDE 0250 T. 814<\/strong><\/td><td>German national standard for crane and reeling cables<\/td><\/tr>\n          <tr><td>Voltage Uo\/U \/ Test<\/td><td><strong>0.6\/1 kV<\/strong>.

Applications include long-travel cranes, stacker-reclaimers, and ship loaders where cable runs of 200\u2013500 metres are guided over roller banks spanning the entire travel length.<\/p>\n    <\/div>\n\n  <\/section>\n\n  <!-- ===== S4 ===== -->\n  <section class=\"body\" id=\"s4\">\n    <h2>7 Three-Phase Power Configurations<\/h2>\n\n    <div class=\"tw\">\n      <table>\n        <caption>NSHTOEu \/3 \u2014 Three-Phase Power Configurations with Split Earth (3\u00d7Phase + 3\u00d7PE\/3)<\/caption>\n        <thead><tr><th>Part No.<\/th><th>Configuration<\/th><th>Rl [\u03a9\/km]<\/th><th>Ibl [A]<\/th><th>\u00d8 min [mm]<\/th><th>\u00d8 max [mm]<\/th><th>\u00d8 [mm]<\/th><th>Fzp [N]<\/th><th>Fzd [N]<\/th><th>Cu [kg\/km]<\/th><th>G [kg\/km]<\/th><\/tr><\/thead>\n        <tbody>\n          <tr><td>050776<\/td><td><strong>3\u00d750+3\u00d725\/3<\/strong><\/td><td>0.393<\/td><td>168<\/td><td>37.1<\/td><td>46.8<\/td><td>46.8<\/td><td>2,250<\/td><td>3,000<\/td><td>1,680<\/td><td>2,730<\/td><\/tr>\n          <tr><td>050777<\/td><td><strong>3\u00d770+3\u00d735\/3<\/strong><\/td><td>0.277<\/td><td>207<\/td><td>42.5<\/td><td>53.5<\/td><td>53.5<\/td><td>3,150<\/td><td>4,200<\/td><td>2,352<\/td><td>3,440<\/td><\/tr>\n          <tr><td>050778<\/td><td><strong>3\u00d795+3\u00d750\/3<\/strong><\/td><td>0.21<\/td><td>250<\/td><td>48.2<\/td><td>60.6<\/td><td>60.6<\/td><td>4,275<\/td><td>5,700<\/td><td>3,216<\/td><td>4,690<\/td><\/tr>\n          <tr><td>050779<\/td><td><strong>3\u00d7120+3\u00d770\/3<\/strong><\/td><td>0.164<\/td><td>292<\/td><td>51.6<\/td><td>64.9<\/td><td>64.9<\/td><td>5,400<\/td><td>7,200<\/td><td>4,128<\/td><td>6,220<\/td><\/tr>\n          <tr><td>050780<\/td><td><strong>3\u00d7150+3\u00d770\/3<\/strong><\/td><td>0.132<\/td><td>335<\/td><td>56.2<\/td><td>70.7<\/td><td>70.7<\/td><td>6,750<\/td><td>9,000<\/td><td>4,992<\/td><td>7,480<\/td><\/tr>\n          <tr><td>050781<\/td><td><strong>3\u00d7185+3\u00d795\/3<\/strong><\/td><td>0.108<\/td><td>382<\/td><td>63.3<\/td><td>79.4<\/td><td>79.4<\/td><td>8,325<\/td><td>11,100<\/td><td>6,240<\/td><td>9,020<\/td><\/tr>\n          <tr><td>050782<\/td><td><strong>3\u00d7240+3\u00d7120\/3<\/strong><\/td><td>0.0817<\/td><td>453<\/td><td>69.9<\/td><td>87.7<\/td><td>87.7<\/td><td>10,800<\/td><td>14,400<\/td><td>8,064<\/td><td>11,760<\/td><\/tr>\n        <\/tbody>\n      <\/table>\n    <\/div>\n\n    <div class=\"note amber\">\n      <div class=\"nt\">Diameter Range Data: \u00d8 min \/ \u00d8 max \/ \u00d8 Nominal<\/div>\n      <p>The NSHTOEu \/3 datasheet uniquely publishes <strong>three diameter values<\/strong> per configuration: \u00d8 min, \u00d8 max, and \u00d8 nominal.

No CORDAFLEX, TROMMELFLEX, or SPREADERFLEX variant makes this claim. This chemical resistance is conferred by the combination of <strong>tinned copper conductors<\/strong> (tin is resistant to dilute acids and alkali solutions), <strong>EPR 3GI3 insulation<\/strong> (inherently resistant to many acids and bases), and the <strong>5GM3 PCP outer sheath<\/strong> (polychloroprene&#8217;s natural resistance to a wide range of chemical agents).<\/p>\n\n    <p>This makes the NSHTOEu \/3 the preferred reeling cable for <strong>chemical and process industry applications<\/strong> where the cable may contact acidic or alkaline process fluids \u2014 including paper mills (alkali pulping chemicals), fertiliser plants (acidic solutions), electroplating facilities (various acid baths), wastewater treatment plants (both acidic and alkaline conditions), food and beverage processing (cleaning chemicals), and pharmaceutical manufacturing (solvent and reagent exposure). The combination of chemical resistance with the 5-mode bending radius table means a single cable can serve as reeling cable, festoon cable, or drag chain cable in chemical processing environments \u2014 eliminating the need for specialised chemical-resistant cable variants in each application mode.<\/p>\n\n  <\/section>\n\n  <!-- ===== S7 ===== -->\n  <section class=\"body\" id=\"s7\">\n    <h2>Construction Details: GM1b Inner Sheath and Split Earth<\/h2>\n\n    <p>The NSHTOEu \/3 uses <strong>rubber GM1b<\/strong> for its inner sheath \u2014 a chloroprene (CR) rubber compound that provides mechanical cushioning between the conductor bundle and the outer protective layers. The &#8220;GM1b&#8221; designation indicates a specific DIN VDE compound grade optimised for the inner sheath role: it absorbs impact stresses from rapid acceleration and deceleration of the reeling mechanism, prevents conductor bundle deformation under sustained tensile load, and provides electrical separation between the core assembly and the polyester torsion braid. This compound is distinct from both the 5GM5 used in premium CORDAFLEX variants and the 5GM3 used for the NSHTOEu \/3&#8217;s own outer sheath \u2014 it is specifically formulated for the internal cushioning function rather than external abrasion resistance.<\/p>\n\n    <p>The <strong>split protective conductors in the outer interstices<\/strong> is a distinctive construction feature of the &#8220;\/3&#8221; designation. Instead of a single full-size earth conductor, the protective earth is split into three half-size conductors positioned in the outer interstices (gaps) between the phase conductors. For example, in the 3\u00d750+3\u00d725\/3 configuration, the &#8220;3\u00d725\/3&#8221; denotes three earth conductors, each 25\/3 \u2248 8.33 mm\u00b2, positioned symmetrically around the cable&#8217;s cross-section. This split earth construction provides three critical advantages: symmetrical cable geometry (improving drum winding behaviour), redundant earth path (if one earth conductor is damaged, two remain), and reduced individual conductor cross-section (improving flexibility per conductor element).<\/p>\n\n    <p>The <strong>black outer sheath colour<\/strong> distinguishes the NSHTOEu \/3 from the yellow-sheathed CORDAFLEX and TROMMELFLEX families, providing immediate visual identification. In multi-cable installations where both premium (yellow) and standard (black) reeling cables are installed on the same crane, the colour coding allows maintenance technicians to instantly identify the cable type without consulting cable markings.<\/p>\n\n  <\/section>\n\n  <!-- ===== S8 ===== -->\n  <section class=\"body\" id=\"s8\">\n    <h2>NSHTOEu \/3 vs. CORDAFLEX (SMK): Position in the Product Hierarchy<\/h2>\n\n    <div class=\"tw\">\n      <table>\n        <caption>NSHTOEu \/3 vs. CORDAFLEX (SMK) \u2014 Technical Comparison for Matching Configurations<\/caption>\n        <thead><tr><th>Parameter<\/th><th>NSHTOEu \/3<\/th><th>CORDAFLEX (SMK)<\/th><th>Assessment<\/th><\/tr><\/thead>\n        <tbody>\n          <tr><td>Conductor Tensile<\/td><td>20 N\/mm\u00b2<\/td><td>30 N\/mm\u00b2<\/td><td>SMK: 50% higher<\/td><\/tr>\n          <tr><td>Conductor<\/td><td>Tinned Cu, Class 5<\/td><td>Tinned Cu, Class FS<\/td><td>SMK: finer stranding<\/td><\/tr>\n          <tr><td>Insulation<\/td><td>EPR 3GI3<\/td><td>Not specified<\/td><td>NSHTOEu: traceable<\/td><\/tr>\n          <tr><td>Inner Sheath<\/td><td>Rubber GM1b<\/td><td>Cross-linked rubber<\/td><td>Different compounds<\/td><\/tr>\n          <tr><td>Outer Sheath<\/td><td>5GM3, Black<\/td><td>PCP, Yellow<\/td><td>SMK: higher grade<\/td><\/tr>\n          <tr><td>Torsion<\/td><td>\u00b125\u00b0\/m<\/td><td>\u00b150\u00b0\/m<\/td><td>SMK: 2\u00d7 torsion<\/td><\/tr>\n          <tr><td>Speed<\/td><td>180 m\/min<\/td><td>240 m\/min<\/td><td>SMK: 33% faster<\/td><\/tr>\n          <tr><td>Cold Rating (Fixed)<\/td><td>\u221240\u00b0C<\/td><td>\u221250\u00b0C<\/td><td>SMK: 10\u00b0C colder<\/td><\/tr>\n          <tr><td>Cold Rating (Moving)<\/td><td>\u221220\u00b0C<\/td><td>\u221235\u00b0C<\/td><td>SMK: 15\u00b0C colder<\/td><\/tr>\n          <tr><td>Test Voltage<\/td><td>3 kV<\/td><td>3.5 kV<\/td><td>SMK: higher test<\/td><\/tr>\n          <tr><td>Dual Fzp\/Fzd<\/td><td><strong>Yes \u2605<\/strong><\/td><td>No (Fzv only)<\/td><td>NSHTOEu: both ratings<\/td><\/tr>\n          <tr><td>Bending Modes<\/td><td><strong>5-mode table \u2605<\/strong><\/td><td>Fixed + Moving only<\/td><td>NSHTOEu: 5 modes<\/td><\/tr>\n          <tr><td>Chemical<\/td><td><strong>Acid + Lye + Oil \u2605<\/strong><\/td><td>Oil only<\/td><td>NSHTOEu: broader<\/td><\/tr>\n          <tr><td>\u00d8 Range Data<\/td><td><strong>Min + Max + Nom \u2605<\/strong><\/td><td>Nominal only<\/td><td>NSHTOEu: 3 values<\/td><\/tr>\n          <tr><td>OD (3\u00d7240+3\u00d7120\/3)<\/td><td>87.7 mm<\/td><td>71.4 mm<\/td><td>SMK: 23% smaller<\/td><\/tr>\n          <tr><td>Weight (3\u00d7240+3\u00d7120\/3)<\/td><td>11,760 kg\/km<\/td><td>11,998 kg\/km<\/td><td>NSHTOEu: 2% lighter<\/td><\/tr>\n        <\/tbody>\n      <\/table>\n    <\/div>\n\n    <div class=\"note green\">\n      <div class=\"nt\">When to Choose NSHTOEu \/3 over CORDAFLEX<\/div>\n      <p><strong>Choose NSHTOEu \/3<\/strong> when: (1) you need a single cable type for multiple application modes (reeling + festoon + drag chain + multi-roller), (2) you operate in chemical\/process environments requiring acid and lye resistance, (3) you need explicit Fzp + Fzd dual tensile data for structural engineering calculations, (4) you need precise diameter tolerance data (\u00d8 min\/max) for mechanical system design, or (5) cost is a primary driver and the application does not require \u226530 N\/mm\u00b2 tensile, \u2265240 m\/min speed, or \u2264\u221235\u00b0C moving cold rating. <strong>Choose CORDAFLEX (SMK)<\/strong> when: maximum tensile strength, maximum reeling speed, extreme cold-climate operation, or minimum OD are critical requirements.<\/p>\n    <\/div>\n\n  <\/section>\n\n  <!-- ===== S9 ===== -->\n  <section class=\"body\" id=\"s9\">\n    <h2>Cost-Effective Alternative from Feichun<\/h2>\n\n    <p><strong>Feichun Lead Times:<\/strong> All 7 three-phase configurations: 4\u20138 weeks (most sizes in stock).

The protective earth (PE) conductor is split into three smaller conductors positioned symmetrically in the outer interstices of the cable&#8217;s cross-section. In the designation &#8220;3\u00d750+3\u00d725\/3&#8221;, the &#8220;3\u00d725\/3&#8221; means three earth conductors each of 25\u00f73 \u2248 8.33 mm\u00b2 cross-section. This provides symmetrical cable geometry, redundant earth path, and improved flexibility compared to a single full-size earth conductor.<\/p>\n\n    <p><strong>Why does the NSHTOEu \/3 use 5GM3 instead of the 5GM5 used by CORDAFLEX XPRT?<\/strong> The 5GM3 is a mid-grade PCP compound per DIN VDE 0207-21 that provides excellent abrasion resistance, oil resistance, and flame retardancy at a lower material cost than the premium 5GM5. For the NSHTOEu \/3&#8217;s target applications \u2014 which prioritise chemical resistance, multi-application versatility, and cost-effectiveness over maximum mechanical performance \u2014 the 5GM3 compound delivers the optimal balance. The 5GM3 still exceeds the requirements for acid, lye, and oil resistance that make this cable unique in the product family.<\/p>\n\n    <p><strong>Why is the torsion rating \u00b125\u00b0\/m instead of the \u00b150\u00b0\/m on CORDAFLEX cables?<\/strong> The \u00b125\u00b0\/m torsion rating reflects the NSHTOEu \/3&#8217;s broader application scope \u2014 particularly festoon and drag chain installations where torsional loads are lower than in drum reeling. In festoon systems, the cable hangs in catenary loops and experiences minimal torsion. In drag chains, the cable follows a fixed path with no rotational component. The \u00b125\u00b0\/m rating is fully adequate for these applications while allowing the polyester torsion braid to be optimised for the cable&#8217;s multi-application bending performance rather than maximum torsion resistance.<\/p>\n\n    <p><strong>Can the NSHTOEu \/3 replace a CORDAFLEX (SMK) on an STS crane?<\/strong> In specific applications, yes \u2014 particularly for auxiliary power circuits, festoon systems, and drag chain installations on the crane where the maximum tensile, speed, and cold-temperature requirements are within the NSHTOEu \/3&#8217;s operating envelope (20 N\/mm\u00b2, 180 m\/min, \u221220\u00b0C moving). For the primary long-travel or trolley-travel reeling drum where maximum tensile and speed are critical, the CORDAFLEX (SMK) or XPRT remains the preferred choice. Many crane operators use <strong>both cables on the same crane<\/strong> \u2014 CORDAFLEX for primary power drums and NSHTOEu \/3 for auxiliary and festoon circuits \u2014 achieving the best balance of performance and cost.<\/p>\n\n    <p><strong>Why is there no short-circuit temperature listed?<\/strong> The NSHTOEu \/3 datasheet does not explicitly list a short-circuit conductor temperature, unlike the CORDAFLEX variants which specify 250\u00b0C. Based on the EPR 3GI3 insulation and the cable&#8217;s conformance to VDE 0250-814, the short-circuit limit is expected to be 250\u00b0C (standard for EPR-insulated cables), but engineers should verify this with the cable manufacturer for fault current calculations. Feichun&#8217;s equivalent is tested and confirmed at 250\u00b0C short-circuit temperature.<\/p>\n\n  <\/section>\n\n  <!-- ===== References ===== -->\n  <section class=\"refs\" id=\"refs\">\n    <h2>References<\/h2>\n    <ol class=\"rl\">\n      <li>Klaus Faber AG, <em>NSHTOEu \/3 \u2014 Product Data Sheet<\/em>, dbl_nshtou3.pdf, Issue 04\/02\/2026.<\/li>\n      <li>Klaus Faber AG, <em>PRYSMIAN CORDAFLEX\u00ae (SMK) (N)SHTOEU \u2014 Product Data Sheet<\/em>, dbl_nshtoeu_smk.pdf, Issue 04\/02\/2026.<\/li>\n      <li>Klaus Faber AG, <em>CORDAFLEX XPRT (N)SHTOEU \u2014 Product Data Sheet<\/em>, dbl_cordaflef_xprt_n_shtoeu.pdf, Issue 04\/02\/2026.<\/li>\n      <li>Prysmian Group, <em>Low Voltage Reeling Cables \u2014 CORDAFLEX \/ TROMMELFLEX<\/em>. <a href=\"https:\/\/www.prysmian.com\/sites\/default\/files\/business_markets\/markets\/downloads\/datasheets\/Low-Voltage-Reeling.pdf\" target=\"_blank\" rel=\"noopener\">prysmian.com<\/a><\/li>\n      <li>DIN VDE 0250 T. 814: <em>Cables for Cranes and Lifting Appliances \u2014 Reeling Cables<\/em>.<\/li>\n      <li>DIN VDE 0207-20: <em>Rubber Compound Types for Insulation \u2014 EPR Compounds (3GI Series)<\/em>.<\/li>\n      <li>DIN VDE 0207-21: <em>Rubber Compound Types for Sheaths \u2014 PCP Compounds (5GM Series)<\/em>.<\/li>\n      <li>IEC 60332-1-2 \/ VDE 0482-332-1-2: <em>Tests on Electric and Optical Fibre Cables Under Fire Conditions<\/em>.<\/li>\n      <li>EN 60811-2-1: <em>Test Methods for Insulation and Sheaths \u2014 Oil Resistance<\/em>.<\/li>\n      <li>FeiChun, <em>NSHTOEU 0.6\/1 kV Drum Reeling Cable \u2014 Complete Technical Solution<\/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    <\/ol>\n  <\/section>\n\n  <div class=\"contact\">\n    <h3>Contact Anhui Feichun Special Cable Co., Ltd. \u2014 NSHTOEu \/3 &#038; Multi-Application Reeling Cable Specialists<\/h3>\n    <div class=\"cg\">\n      <div class=\"ci\"><span class=\"lb\">Technical Specifications &#038; Engineering<\/span><a href=\"mailto:Tech@feichuncables.com\">Tech@feichuncables.com<\/a><\/div>\n      <div class=\"ci\"><span class=\"lb\">Port &#038; 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 &#038; 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&#8217;s proprietary equivalent to the NSHTOEu \/3 rubber reeling cable, incorporating FC-FLX<span class=\"tm\">\u2122<\/span> Class 5 flexible tinned Tongling copper conductors, EPR 3GI3 insulation per DIN VDE 0207-20, rubber GM1b inner sheath, polyester braid torsion protection (\u00b125\u00b0\/m), and Gummi 5GM3 PCP outer sheath (black).
