<section class=\"body\" id=\"s1\">\n    <h2>Introduction: The Copper-Only Spreader Cable with the Best Insulation<\/h2>\n\n    <p>SPREADERFLEX REEL XPRT (N)SHTOEU is the <strong>copper-only counterpart<\/strong> of the Cordaflex (SMK)-V-FO \u2014 sharing the same Class FS conductors, aramide self-supporting element, PCP rubber sheath, and 240 m\/min vertical reeling capability, but without integrated fiber optics. It is designed for the large installed base of STS crane spreaders that do not require fiber optic communication \u2014 spreaders using copper-only control signals, or cranes where fiber optic data is provided through a separate dedicated cable or wireless link.<\/p>\n\n    <p>But the REEL XPRT is not merely the (SMK)-V-FO minus fiber. It introduces a critical insulation upgrade: <strong>ETFE (ethylene tetrafluoroethylene)<\/strong> \u2014 a fluoropolymer insulation that is categorically superior to the polyolefin used in the (SMK)-V-FO and the EPR 3GI3 used in every other cable in this guide series. ETFE achieves <strong>80\u2013100 kV\/mm dielectric strength<\/strong> (vs. ~20 kV\/mm for EPR), withstands the <strong>250\u00b0C short-circuit<\/strong> temperature (explicitly rated on this datasheet but not on the (SMK)-V-FO), and resists virtually every industrial chemical, solvent, and acid. Combined with the <strong>penta-environmental certification<\/strong> (flame + UV + oil + ozone + water \u2014 the most comprehensive of any cable in this guide), the REEL XPRT represents the absolute highest-specification copper-only vertical spreader cable available.<\/p>\n\n    <div class=\"note red\">\n      <div class=\"nt\">ETFE Insulation Requires Special Termination Techniques<\/div>\n      <p>ETFE is a fluoropolymer \u2014 it cannot be stripped with standard hot-knife or rotary blade cable stripping tools designed for EPR or polyolefin. ETFE requires <strong>precision mechanical stripping<\/strong> using tools with controlled depth settings to avoid nicking the Class FS copper strands beneath the thin ETFE wall. Feichun provides detailed ETFE termination instructions with every cable shipment and offers pre-assembled cable assemblies with factory-terminated connectors for customers who prefer to avoid field termination of ETFE insulation.<\/p>\n    <\/div>\n\n  <\/section>\n\n  <!-- ===== S2 ===== -->\n  <section class=\"body\" id=\"s2\">\n    <h2>Technical Anatomy: Full Specification<\/h2>\n\n    <div class=\"tw\">\n      <table>\n        <caption>SPREADERFLEX REEL XPRT Specifications (per Klaus Faber Datasheet dbl_spreaderflex_reel_xprt.pdf, Issue 04\/01\/2026)<\/caption>\n        <thead><tr><th>Parameter<\/th><th>Specification<\/th><th>vs. Cordaflex (SMK)-V-FO<\/th><\/tr><\/thead>\n        <tbody>\n          <tr><td>Standard<\/td><td><strong>DIN VDE 0250-814<\/strong><\/td><td>Same<\/td><\/tr>\n          <tr><td>Voltage \/ Test<\/td><td>0.6\/1 kV.

Container crane spreaders operate in an environment where hydraulic oil from twist-lock actuators, diesel exhaust from auxiliary generators, saltwater spray from below, and cleaning solvents from deck-wash operations all contact the cable surface and can migrate through sheath damage to reach the insulation. Where polyolefin or EPR would swell, soften, or degrade over years of chemical exposure, ETFE remains chemically inert \u2014 its fluoropolymer backbone is impervious to virtually every industrial chemical encountered in port operations.<\/p>\n\n  <\/section>\n\n  <!-- ===== S5 ===== -->\n  <section class=\"body\" id=\"s5\">\n    <h2>20\u00d7OD S-Type Directional Change: The Unique Mechanical Specification<\/h2>\n\n    <p>The REEL XPRT introduces a specification that no other cable in this guide series provides: <strong>minimum distance with S-type directional changes: 20\u00d7OD<\/strong>. This defines the minimum straight-cable length required between two opposing bends (an &#8220;S-curve&#8221;) during cable routing. For the 56\u00d72.5 at 43.1 mm max OD: 20 \u00d7 43.1 = <strong>862 mm minimum<\/strong> between reverse bends.<\/p>\n\n    <p>S-type directional changes occur at specific locations in vertical spreader reel systems: where the cable exits the reel drum, passes through a guide roller, changes direction, and enters the vertical drop shaft. This transition creates an S-curve with two opposing bends in rapid succession. If the straight section between the bends is too short, the cable experiences combined bending and torsional stress that exceeds the limits of any single-bend specification. The 20\u00d7OD minimum ensures the cable has sufficient length to relax between bends \u2014 preventing the cumulative stress that causes accelerated fatigue at S-curve transition points. Crane designers must verify that their reel departure geometry provides at least 20\u00d7OD straight-cable distance between opposing guide rollers.<\/p>\n\n  <\/section>\n\n  <!-- ===== S6 ===== -->\n  <section class=\"body\" id=\"s6\">\n    <h2>Penta-Environmental Certification: Five Simultaneous Resistances<\/h2>\n\n    <p>The REEL XPRT achieves <strong>five independently certified environmental resistances<\/strong> \u2014 the most comprehensive environmental certification of any cable in this guide:<\/p>\n\n    <div class=\"tw\">\n      <table>\n        <caption>Penta-Environmental Certification<\/caption>\n        <thead><tr><th>#<\/th><th>Property<\/th><th>Standard<\/th><\/tr><\/thead>\n        <tbody>\n          <tr><td>1<\/td><td><strong>Flame Retardant<\/strong><\/td><td>VDE 0482-332-1-2 \/ IEC 60332-1-2<\/td><\/tr>\n          <tr><td>2<\/td><td><strong>UV Resistant<\/strong><\/td><td>Yes<\/td><\/tr>\n          <tr><td>3<\/td><td><strong>Oil Resistant<\/strong><\/td><td>Yes<\/td><\/tr>\n          <tr><td>4<\/td><td><strong>Ozone Resistant<\/strong><\/td><td>Yes<\/td><\/tr>\n          <tr><td>5<\/td><td><strong>Water Resistant<\/strong><\/td><td>Yes<\/td><\/tr>\n        <\/tbody>\n      <\/table>\n    <\/div>\n\n    <p>This penta-certification is achievable because the 5GM5 PCP (polychloroprene) outer sheath is the toughest standard sheath compound in the VDE system, providing inherent flame retardancy, oil resistance, and ozone resistance.

The 5\u00d7OD moving specification reflects ETFE&#8217;s higher modulus at the bending point \u2014 it resists deformation more than polyolefin, requiring a marginally larger radius to avoid insulation micro-cracking during millions of dynamic bending cycles. The (SMK)-V-FO&#8217;s softer polyolefin insulation achieves 4\u00d7OD moving. The practical impact: the REEL XPRT requires a reel drum core diameter approximately 20% larger than the (SMK)-V-FO at equivalent OD. For the 56\u00d72.5 at 43.1 mm max OD: REEL XPRT minimum drum core radius = 5 \u00d7 43.1 = 216 mm; (SMK)-V-FO minimum = 4 \u00d7 44.3 = 177 mm.<\/p>\n\n    <h3>Why 4\u00d7OD fixed but 5\u00d7OD moving? Shouldn&#8217;t fixed be larger?<\/h3>\n    <p>This is counterintuitive but correct. In fixed installation (cable permanently bent and not moving), the cable experiences static bending stress but no fatigue cycling. ETFE&#8217;s high yield strength allows it to sustain a tighter static bend (4\u00d7OD) without permanent deformation. In moving applications (dynamic reeling), the cable experiences millions of bending cycles \u2014 and ETFE&#8217;s slightly higher stiffness means each cycle generates more micro-stress at 4\u00d7OD than polyolefin would. The 5\u00d7OD moving specification provides the fatigue margin needed for the cable&#8217;s target 10+ year dynamic service life.<\/p>\n\n    <h3>Can I add fiber optics to a REEL XPRT cable?<\/h3>\n    <p>No \u2014 the REEL XPRT is a copper-only design with all interstices occupied by copper control cores and the aramide self-supporting element. Adding fiber tubes would require removing copper cores, changing the cable geometry, and creating a different product \u2014 which is precisely the Cordaflex (SMK)-V-FO. If you need both copper and fiber in a single vertical spreader cable, specify the (SMK)-V-FO instead.<\/p>\n\n    <h3>What is ETFE and why is it not used in every cable?<\/h3>\n    <p>ETFE (ethylene tetrafluoroethylene) is a fluorinated copolymer manufactured by companies including Chemours (Tefzel\u00ae), AGC (Fluon\u00ae), and Daikin. It costs approximately 8\u201312\u00d7 more per kilogram than standard EPR insulation compound. This cost premium \u2014 multiplied across 56 cores \u2014 significantly increases the cable&#8217;s material cost. ETFE is specified only where its superior properties (extreme dielectric strength, chemical inertness, thin-wall capability, and 250\u00b0C short-circuit survival) are essential. For standard horizontal drum reeling where EPR or rubber insulation provides adequate performance, ETFE&#8217;s cost premium is not justified.<\/p>\n\n  <\/section>\n\n  <!-- ===== S10 ===== -->\n  <section class=\"refs\" id=\"s10\">\n    <h2>References<\/h2>\n    <ol class=\"rl\">\n      <li>Klaus Faber AG, <em>SPREADERFLEX REEL XPRT (N)SHTOEU \u2014 Product Data Sheet<\/em>, dbl_spreaderflex_reel_xprt.pdf, Issue 04\/01\/2026.<\/li>\n      <li>Klaus Faber AG, <em>PRYSMIAN Cordaflex\u00ae (N)SHTOEU (SMK)-V-FO \u2014 Product Data Sheet<\/em>, dbl_nshtoeu_smk_v_fo.pdf (companion FO variant).<\/li>\n      <li>FeiChun, <em>PRYSMIAN\u00ae SPREADERFLEX XTRM (N)SHT11Y \u2014 ETFE Insulation Analysis<\/em>. <a href=\"https:\/\/feichuncables.com\/blog\/prysmian-spreaderflex-xtrmnsht11y\/\" target=\"_blank\" rel=\"noopener\">feichuncables.com<\/a><\/li>\n      <li>FeiChun, <em>Spreader Cable Reel Engineering Guide<\/em>. <a href=\"https:\/\/feichuncables.com\/blog\/spreader-cable-reel-engineering-guide-vertical-reeling-systems-aramid-core-strain-relief-and-gravity-stress-management-for-modern-sts-and-rtg-container-cranes\/\" 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 \/ VDE 0298-4.<\/li>\n    <\/ol>\n  <\/section>\n\n  <div class=\"contact\">\n    <h3>Contact Anhui Feichun Special Cable Co., Ltd. \u2014 ETFE &#038; Class FS Vertical 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 SPREADERFLEX REEL XPRT (N)SHTOEU vertical spreader reeling cable, incorporating FC-FLX<span class=\"tm\">\u2122<\/span> Class FS exceptionally fine stranded bare Tongling copper conductors, ETFE fluoropolymer insulation, aramide self-supporting element, polyester braid torsion protection (\u00b150\u00b0\/m), and rubber (PCP) 5GM5 outer sheath.
