<h2>Introduction: The Most Demanding Cable Application in Port Engineering<\/h2>\n\n    <p>Prysmian<span class=\"tm\">\u00ae<\/span> SPREADERFLEX XTRM (N)SHT11Y is the <strong>most mechanically extreme vertical reeling cable<\/strong> in the global port crane cable portfolio\u2014a 0.6\/1 kV composite power, control, and CAN-BUS communication cable engineered exclusively for the application that destroys ordinary cables faster than any other in the maritime industry: <strong>vertical reeling on mobile harbour cranes<\/strong>.<\/p>\n\n    <p>A mobile harbour crane\u2014the Liebherr LHM series, Gottwald HMK\/G HMK series, or Konecranes mobile harbour crane\u2014is fundamentally different from a fixed Ship-to-Shore gantry crane. It moves on wheels or rails along the quay, deploys its boom to reach over vessel holds, and lifts cargo using a vertical reeling system that feeds the main supply cable from a motorized reel mounted on the crane&#8217;s upper structure down to the hook block or spreader 40\u201390 metres below. The cable free-hangs vertically, swinging with the crane&#8217;s boom movement, subject to wind loading, vessel-induced motion, and the violent acceleration and deceleration of the hoist cycle at speeds up to 160 m\/min.<\/p>\n\n    <p>This is not gentle operation. During a container or heavy-lift cycle, the cable experiences: gravitational tensile loading from 90 metres of self-weight (potentially exceeding 15 kN for a cable weighing 1,575 kg\/km), dynamic shock loading during hoist start and emergency stop (requiring 20 kN breaking load capacity), tight bending at 4\u00d7 OD as the cable transitions from vertical to the reel drum, S-type directional reversals at 20\u00d7 OD as the cable navigates guide rollers, \u00b150\u00b0\/m torsional allowance as the cable twists during boom slewing, and continuous abrasion as the cable contacts drum flanges, guide sheaves, and structural members at 160 m\/min. Simultaneously, the cable must deliver power to the spreader\/hook block systems, carry control signals for all spreader functions, and transmit CAN-BUS data for real-time crane automation\u2014without signal degradation from the electromagnetic interference generated by the power cores.<\/p>\n\n    <p>Feichun&#8217;s equivalent to the SPREADERFLEX XTRM integrates every innovation developed across the entire PROTOLON<span class=\"tm\">\u00ae<\/span> range: <strong>FC-FLX<span class=\"tm\">\u2122<\/span> Class FS Tongling copper conductors<\/strong>, <strong>FC-ASB<span class=\"tm\">\u2122<\/span> aramid-reinforced PUR<\/strong> outer sheath, and <strong>ETFE fluoropolymer insulation<\/strong> that provides the thermal, chemical, and mechanical endurance margin necessary for a cable that must survive in the most violent reeling environment in the crane industry.<\/p>\n\n    <div class=\"note red\">\n      <div class=\"nt\">Application-Critical Cable<\/div>\n      <p>SPREADERFLEX XTRM is not a generic reeling cable. It is a machine-specific cable engineered for the unique stress profile of mobile harbour crane vertical reeling\u2014combining extreme suspension height, extreme dynamic loading, extreme bending, and integrated data communication in a single structure. Substituting a standard reeling cable\u2014even a premium multi-core PUR reeling cable\u2014will result in premature failure from insufficient tensile strength, inadequate self-supporting capacity, or CAN-BUS signal degradation. Always specify the SPREADERFLEX XTRM equivalent for mobile harbour crane vertical reel applications.<\/p>\n    <\/div>\n\n  <\/section>\n\n  <!-- ===== S2 ===== -->\n  <section class=\"body\" id=\"s2\">\n    <h2>Technical Anatomy: Full Specification Breakdown<\/h2>\n\n    <div class=\"tw\">\n      <table>\n        <caption>SPREADERFLEX XTRM (N)SHT11Y Technical Specifications (DIN VDE 0250-814)<\/caption>\n        <thead>\n          <tr>\n            <th>Parameter<\/th>\n            <th>Specification<\/th>\n          <\/tr>\n        <\/thead>\n        <tbody>\n          <tr><td>Standard<\/td><td>DIN VDE 0250-814 (with ref. to)<\/td><\/tr>\n          <tr><td>Voltage Rating (U\u2080\/U)<\/td><td>0.6\/1 kV.

Its construction integrates eight distinct functional layers, each engineered to solve a specific failure mode unique to mobile harbour crane vertical reeling. Understanding this architecture is essential for appreciating why this cable exists as a separate product and cannot be substituted with simpler reeling cables.<\/p>\n\n    <p><strong>Layer 1 \u2014 Central Self-Supporting Element:<\/strong> Aramid (para-aramid) fibers with rubber covering form the cable&#8217;s tensile backbone. Positioned at the geometric centre, the aramid carries the entire 90 m of gravitational self-weight (approximately 14.2 kN at full suspension), transferring the load away from the ductile copper conductors. The rubber covering protects the aramid from mechanical abrasion during manufacture and provides a smooth surface for the subsequent core layers to wrap around.<\/p>\n\n    <p><strong>Layer 2 \u2014 CAN-BUS Communication Pair:<\/strong> At the cable&#8217;s core, adjacent to the self-supporting element, a dedicated CAN-BUS twisted pair occupies the most mechanically protected position. The pair uses bare copper Class 5 conductors with <strong>foam-skin polypropylene (PP) insulation<\/strong>\u2014a low-capacitance insulation specifically selected for high-frequency bus communication. Aluminium foil wraps the twisted pair for primary shielding, then a <strong>tinned copper braid screen<\/strong> provides secondary shielding with 360\u00b0 EMI protection. An <strong>Ultramid<span class=\"tm\">\u00ae<\/span> (polyamide) covering<\/strong> encases the entire CAN-BUS element, providing additional mechanical protection and moisture barrier. This multi-layer shielding architecture ensures CAN-BUS signal integrity even surrounded by 37 power and control cores generating electromagnetic interference.<\/p>\n\n    <p><strong>Layer 3 \u2014 Inner Core Ring (5\u00d73\u00d72.5 mm\u00b2):<\/strong> Fifteen ETFE-insulated Class FS conductors arranged in five groups of three, wrapped with foil spinning, forming the inner core layer around the central elements. These cores typically carry the primary power and critical control functions.<\/p>\n\n    <p><strong>Layer 4 \u2014 Fillers and PP Yarns:<\/strong> Polypropylene filler yarns fill the geometric voids between the inner core ring elements, maintaining perfect cable roundness and preventing core migration under mechanical stress.<\/p>\n\n    <p><strong>Layer 5 \u2014 Outer Core Ring (22\u00d72.5 mm\u00b2):<\/strong> Twenty-two ETFE-insulated Class FS conductors arranged as the outer layer, wrapped with foil spinning and fleece spinning for mechanical cushioning. These cores carry auxiliary power, control, sensor, and safety interlock functions.<\/p>\n\n    <p><strong>Layer 6 \u2014 PUR Inner Sheath:<\/strong> Polyurethane inner sheath encases the complete core assembly, providing intermediate mechanical protection and environmental barrier.<\/p>\n\n    <p><strong>Layer 7 \u2014 Polyester Braid Armour + Synthetic Torsion Braid:<\/strong> Reinforcing polyester braid provides radial crush resistance and longitudinal tensile contribution. Synthetic torsion braid prevents axial rotation, allowing \u00b150\u00b0\/m controlled torsion for boom slewing accommodation.<\/p>\n\n    <p><strong>Layer 8 \u2014 FC-ASB\u2122 Aramid-Reinforced PUR Outer Sheath:<\/strong> The final outer barrier\u2014aramid fiber-reinforced polyurethane providing bulletproof-grade abrasion resistance, UV protection, oil resistance, ozone resistance, and water resistance for permanent outdoor exposure on mobile harbour crane structures.<\/p>\n\n    <div class=\"note blue\">\n      <div class=\"nt\">Engineering Complexity<\/div>\n      <p>SPREADERFLEX XTRM contains more distinct functional layers than any other cable in the Feichun product range. Each layer exists because field failure data from mobile harbour crane operations identified a specific failure mode that the layer addresses. This is not over-engineering\u2014it is the minimum construction required to survive the 90 m vertical reeling environment at 160 m\/min with integrated CAN-BUS communication.<\/p>\n    <\/div>\n\n  <\/section>\n\n  <!-- ===== S4 ===== -->\n  <section class=\"body\" id=\"s4\">\n    <h2>ETFE Insulation: Why a Fluoropolymer Changes Everything<\/h2>\n\n    <h3>ETFE: The Aerospace-Grade Insulation Material<\/h3>\n\n    <p><strong>ETFE (Ethylene Tetrafluoroethylene)<\/strong> is a fluoropolymer\u2014a member of the same chemical family as PTFE (Teflon<span class=\"tm\">\u00ae<\/span>). It is used as wire insulation in aerospace, military, nuclear, and extreme-environment applications where standard thermoplastic insulation compounds cannot survive. Selecting ETFE for a port crane reeling cable is a deliberate premium engineering decision that delivers four critical advantages over EPR, XLPE, PVC, or standard thermoplastic insulation.<\/p>\n\n    <p><strong>Superior Thermal Endurance:<\/strong> ETFE maintains full dielectric integrity from \u2212200\u00b0C to +150\u00b0C continuously (rated conservatively at 90\u00b0C for cable applications with substantial safety margin). The 250\u00b0C short-circuit rating is among the highest available for any polymer insulation system. In the vertical reeling environment where the cable passes over sun-heated metal drum surfaces and through high-temperature zones near crane drive motors, ETFE provides thermal headroom that standard insulation compounds cannot match.<\/p>\n\n    <p><strong>Exceptional Chemical Resistance:<\/strong> ETFE is chemically inert to virtually all industrial chemicals encountered in port environments: hydraulic oils, diesel fuel, seawater, de-icing chemicals, lubricating greases, cleaning solvents, and ozone. Port cranes operate in one of the most chemically diverse environments in industry\u2014the cable contacts different chemicals depending on what cargo is being handled, what maintenance is being performed, and what environmental conditions exist. ETFE eliminates chemical compatibility concerns entirely.<\/p>\n\n    <p><strong>Mechanical Toughness:<\/strong> Unlike PTFE (which is relatively soft), ETFE has exceptional cut-through resistance and abrasion resistance. In the 37-core cable structure where cores slide against each other during every bending cycle, ETFE&#8217;s surface hardness prevents the inter-core abrasion that degrades softer insulation materials over millions of cycles. The insulation maintains its dielectric thickness throughout the cable&#8217;s operational life\u2014critical for maintaining insulation resistance between adjacent power and signal cores.<\/p>\n\n    <p><strong>Thin-Wall Capability:<\/strong> ETFE&#8217;s high dielectric strength (80\u2013100 kV\/mm) permits thinner insulation walls than EPR or XLPE at equivalent voltage rating. Thinner insulation means smaller core diameter, which means a smaller overall cable OD\u2014critical for fitting 37 power\/control cores plus a CAN-BUS pair into a 30 mm OD package that must navigate 4\u00d7 OD bending radii.<\/p>\n\n    <div class=\"tw\">\n      <table>\n        <caption>ETFE vs. Standard Insulation Materials for Vertical Reeling Cables<\/caption>\n        <thead>\n          <tr><th>Property<\/th><th>PVC<\/th><th>EPR<\/th><th>XLPE<\/th><th>ETFE (This Cable)<\/th><\/tr>\n        <\/thead>\n        <tbody>\n          <tr><td>Continuous Temperature<\/td><td>70\u00b0C<\/td><td>80\u201390\u00b0C<\/td><td>90\u00b0C<\/td><td class=\"g\">90\u00b0C (rated) \/ 150\u00b0C (capable)<\/td><\/tr>\n          <tr><td>Short-Circuit Temperature<\/td><td>160\u00b0C<\/td><td>220\u00b0C<\/td><td>250\u00b0C<\/td><td class=\"g\">250\u00b0C<\/td><\/tr>\n          <tr><td>Chemical Resistance<\/td><td>Limited<\/td><td>Good<\/td><td>Good<\/td><td class=\"g\">Exceptional \u2014 virtually inert<\/td><\/tr>\n          <tr><td>Cut-Through Resistance<\/td><td>Low<\/td><td>Low\u2013Moderate<\/td><td>Moderate<\/td><td class=\"g\">High<\/td><\/tr>\n          <tr><td>Dielectric Strength<\/td><td>15\u201330 kV\/mm<\/td><td>20\u201330 kV\/mm<\/td><td>20\u201340 kV\/mm<\/td><td class=\"g\">80\u2013100 kV\/mm<\/td><\/tr>\n          <tr><td>Wall Thickness (equiv. voltage)<\/td><td>Thickest<\/td><td>Moderate<\/td><td>Moderate<\/td><td class=\"g\">Thinnest<\/td><\/tr>\n          <tr><td>Cold Flexibility<\/td><td>Poor below \u221215\u00b0C<\/td><td>Good to \u221240\u00b0C<\/td><td>Moderate to \u221230\u00b0C<\/td><td class=\"g\">Excellent to \u221250\u00b0C+<\/td><\/tr>\n        <\/tbody>\n      <\/table>\n    <\/div>\n\n  <\/section>\n\n  <!-- ===== S5 ===== -->\n  <section class=\"body\" id=\"s5\">\n    <h2>90-Metre Suspension: Aramid Architecture for the Tallest Harbour Cranes<\/h2>\n\n    <p>The <strong>90-metre suspension height<\/strong> rating of SPREADERFLEX XTRM is the highest of any cable in the Feichun port crane range\u2014nearly double the 50 m rating of the SPREADERFLEX BSKT XPRT basket cable. This reflects the operational reality of modern mobile harbour cranes: the largest Liebherr LHM 800 and Gottwald G HMK 8710 models operate with boom tip heights exceeding 55 metres and working radii requiring 70\u201390 metres of vertical cable suspension between the upper reel and the hook block.<\/p>\n\n    <p>At 90 metres of suspension, a cable weighing 1,575 kg\/km generates a gravitational tensile force of approximately <strong>14.2 kN<\/strong> (1,448 kg-force) at the top attachment point. The aramid self-supporting element must carry this static load continuously while simultaneously absorbing the dynamic shock loads that occur during hoist start, hoist stop, emergency stop, and wind-induced pendulation. The 20 kN dynamic breaking load provides a safety factor of approximately 1.4\u00d7 above the maximum static gravitational load\u2014sufficient to absorb the transient dynamic forces without approaching the aramid&#8217;s ultimate tensile strength.<\/p>\n\n    <p>The aramid fibers are positioned at the cable&#8217;s geometric centre\u2014the position of minimum bending strain when the cable wraps around the reel drum. This central positioning ensures that the load-bearing element experiences the least mechanical fatigue during continuous reel cycling, maximising its operational life. The rubber covering around the aramid core provides abrasion protection against the inner conductor layers and serves as a compliance layer that distributes radial compression forces evenly across the aramid cross-section during drum winding.<\/p>\n\n  <\/section>\n\n  <!-- ===== S6 ===== -->\n  <section class=\"body\" id=\"s6\">\n    <h2>Integrated CAN-BUS: Real-Time Machine Intelligence Over a Single Cable<\/h2>\n\n    <h3>Why CAN-BUS Inside the Power Cable?<\/h3>\n\n    <p>Modern mobile harbour cranes use CAN-BUS (Controller Area Network) as the primary communication protocol between the crane&#8217;s main PLC and the spreader\/hook block systems. CAN-BUS carries real-time control commands (twist-lock actuation, flap control, trim and list adjustment), sensor feedback (load cell data, position encoders, limit switches), safety interlock status, and diagnostic information. Running the CAN-BUS as a separate cable alongside the power cable creates two problems: the separate data cable must survive the identical mechanical environment as the power cable (requiring expensive duplicate construction), and electromagnetic interference from the power cable&#8217;s adjacent conductors degrades CAN-BUS signal quality.<\/p>\n\n    <p>SPREADERFLEX XTRM integrates the CAN-BUS pair directly into the cable&#8217;s core structure with a dedicated multi-layer shielding system: foam-skin PP insulation (low capacitance for high-frequency signal integrity), aluminium foil (primary electrostatic shielding), tinned copper braid (secondary electromagnetic shielding), and Ultramid\u00ae polyamide covering (mechanical protection and moisture barrier). This architecture provides CAN-BUS signal integrity equivalent to a dedicated data cable, while eliminating the cost, complexity, and reliability risk of a separate cable.<\/p>\n\n    <h3>Foam-Skin PP Insulation: The Signal Integrity Secret<\/h3>\n\n    <p>The CAN-BUS pair uses <strong>foam-skin polypropylene (PP) insulation<\/strong>\u2014a specialised low-density insulation where the polypropylene is expanded to create a controlled foam structure with a thin solid skin. This foam structure reduces the dielectric constant from PP&#8217;s bulk value of approximately 2.3 to approximately 1.5\u20131.8 (approaching air&#8217;s dielectric constant of 1.0). The lower dielectric constant dramatically reduces the capacitance per unit length of the twisted pair, which in turn extends the maximum reliable CAN-BUS communication distance and improves signal rise-time performance\u2014critical for maintaining reliable 1 Mbit\/s CAN-BUS communication over 90 metres of cable length subject to continuous mechanical flexing.<\/p>\n\n  <\/section>\n\n  <!-- ===== S7 ===== -->\n  <section class=\"body\" id=\"s7\">\n    <h2>20 kN Dynamic Breaking Load: Engineered for Shock and Surge<\/h2>\n\n    <p>The <strong>20 kN (2,040 kg-force) dynamic breaking load<\/strong> specification is the cable&#8217;s ultimate mechanical safety limit\u2014the maximum instantaneous tensile force the cable can withstand without structural failure. This is not the operating load (which is the static gravitational self-weight of 14.2 kN at full 90 m suspension) but the peak dynamic load that occurs during the most violent transient events in the crane&#8217;s operational cycle.<\/p>\n\n    <p>The most severe dynamic load event is an <strong>emergency hoist stop<\/strong> at full speed. If the crane&#8217;s hoist system decelerates from 160 m\/min to zero in 0.5 seconds (a typical emergency stop time for modern mobile harbour cranes), the cable at the top attachment point experiences an inertial load equal to the cable&#8217;s mass multiplied by the deceleration (approximately 5.3 m\/s\u00b2). For 90 m of cable weighing 1,575 kg\/km, this dynamic inertial load adds approximately 7.5 kN to the static gravitational load of 14.2 kN\u2014totalling approximately 21.7 kN. The 20 kN breaking load specification, combined with the safety margin provided by the aramid self-supporting element&#8217;s ultimate strength (which significantly exceeds 20 kN), ensures survival even under worst-case emergency stop conditions with adequate engineering margin.<\/p>\n\n    <p>The 20 kN specification is a <strong>dynamic<\/strong> rating (designated Fzd in the Klaus Faber datasheet), meaning it is measured under cyclic loading conditions that simulate real operational stress. This is more stringent than static breaking load tests, which measure a single pull-to-failure under constant load rate. Dynamic testing confirms that the cable survives repeated shock events without progressive degradation of the aramid, conductor, or jacket structures.<\/p>\n\n  <\/section>\n\n  <!-- ===== S8 ===== -->\n  <section class=\"body\" id=\"s8\">\n    <h2>4\u00d7OD Bending and S-Type Directional Changes: Extreme Routing Flexibility<\/h2>\n\n    <p>SPREADERFLEX XTRM achieves a remarkable <strong>4\u00d7 OD single-bend radius<\/strong> (120 mm for the 30 mm OD cable)\u2014one of the tightest bending radii specified for any multi-core reeling cable. This is achieved through the synergy of Class FS ultra-fine-stranded conductors (which flex with minimal internal stress), ETFE insulation (which maintains dielectric integrity at extreme bending strain), and the dual-layer PUR\/polyester braid sheath system (which provides jacket elasticity at tight radii).<\/p>\n\n    <p>The <strong>5\u00d7 OD moving bending radius<\/strong> (150 mm) applies to continuous dynamic operation at 160 m\/min\u2014the radius at which the cable is qualified for multi-million-cycle reel operation without conductor fatigue or insulation degradation. The <strong>20\u00d7 OD minimum distance for S-type directional changes<\/strong> (600 mm) specifies the minimum straight-cable distance required between two consecutive reverse bends (such as when the cable passes over a guide sheave, straightens, then passes under a redirector sheave). This specification prevents residual bending stress from one bend from compounding with stress from the subsequent bend\u2014eliminating the stress-multiplication effect that causes accelerated fatigue failure at S-type direction changes.<\/p>\n\n    <p>The <strong>\u00b150\u00b0\/m torsion allowance<\/strong> is critical for mobile harbour cranes that slew (rotate) during operation. As the crane&#8217;s upper structure rotates, the vertically hanging cable twists. Without adequate torsional compliance, this twisting would impose destructive shear forces on the cable&#8217;s internal geometry. The \u00b150\u00b0\/m allowance means the cable tolerates up to 50 degrees of twist per metre of cable length without internal damage\u2014sufficient for the slewing angles of all modern mobile harbour cranes.<\/p>\n\n  <\/section>\n\n  <!-- ===== S9 ===== -->\n  <section class=\"body\" id=\"s9\">\n    <h2>Real-World Applications: Mobile Harbour Cranes and Beyond<\/h2>\n\n    <h3>Mobile Harbour Cranes: The Exclusive Application<\/h3>\n\n    <p>SPREADERFLEX XTRM is designed for one application: the vertical reeling system on mobile harbour cranes.

Fixed STS cranes typically use horizontal reeling cables (BUFLEX SEM, RHEYFIRM RTS) or basket festoon cables (SPREADERFLEX BSKT XPRT). While SPREADERFLEX XTRM could technically be used on an STS crane, it is over-specified for that application and more expensive than the purpose-built alternatives.<\/p>\n\n    <h3>What is the CAN-BUS transmission rate capability?<\/h3>\n    <p>The integrated CAN-BUS pair supports standard CAN 2.0A\/2.0B communication at data rates up to 1 Mbit\/s over the full 90 m cable length. The foam-skin PP insulation and dual foil\/braid shielding ensure bit error rates below 10\u207b\u2078 at 1 Mbit\/s even under worst-case EMI conditions from the adjacent 37 power\/control cores.

ETFE extrusion requires higher temperatures and more precise control than standard thermoplastic processing\u2014Feichun&#8217;s investment in dedicated fluoropolymer extrusion equipment ensures consistent ETFE wall thickness, dielectric properties, and surface quality across all production batches.<\/p>\n\n    <h3>Can Feichun supply alternative core counts or additional CAN-BUS pairs?<\/h3>\n    <p>Yes. The standard 37\u00d72.5+1\u00d7CAN-BUS configuration matches the Prysmian original. Feichun can also manufacture custom configurations with different core counts (24, 30, 42, or 48 power\/control cores), additional CAN-BUS pairs (2\u00d7 or 3\u00d7 for redundant communication), or substitution of CAN-BUS with Ethernet (Cat 5e\/Cat 6) twisted pairs for cranes using PROFINET or EtherCAT communication.

Lower-utilisation cranes extend cable life to 5\u20138 years. FC-FLX\u2122 Class FS conductors are projected to extend these intervals by 30\u201350% compared to standard Class FS conductors, based on Feichun&#8217;s accelerated lifecycle testing data. Annual visual inspection and CAN-BUS signal quality monitoring are recommended to track cable condition and plan replacement proactively.<\/p>\n\n  <\/section>\n\n  <!-- ===== S12 ===== -->\n  <section class=\"refs\" id=\"s12\">\n    <h2>References and Standards<\/h2>\n    <ol class=\"rl\">\n      <li>Anhui Feichun Special Cable Co., Ltd., <em>SPREADERFLEX XTRM (N)SHT11Y Vertical Reeling Cable with ETFE Insulation and Integrated CAN-BUS \u2014 Technical Data Sheet<\/em>, Revision 2.0, 2026.<\/li>\n      <li>Klaus Faber AG, <em>Prysmian\u00ae SPREADERFLEX XTRM (N)SHT11Y \u2014 Product Data Sheet<\/em>, dbl_spreaderflex_xtrm_v-s_n-sht11y.pdf, Issue 03\/31\/2026.<\/li>\n      <li>DIN VDE 0250-814, <em>Flexible cables and cords for vertical reeling operation under extreme mechanical stress<\/em>.<\/li>\n      <li>VDE 0298-3, <em>Bending radii for flexible cables<\/em>.<\/li>\n      <li>VDE 0298-4, <em>Current carrying capacity for cables and conductors<\/em>.<\/li>\n      <li>ISO 11898 (2015), <em>Road vehicles \u2014 Controller area network (CAN) \u2014 Physical layer requirements<\/em>.<\/li>\n      <li>IEC 60228 (2004), <em>Conductors of insulated cables<\/em>.<\/li>\n      <li>GB\/T 467 (2010), <em>Cathode copper<\/em>.
