<h2>Introduction: When Heavy Duty Demands More Than FISMIAN GroupLIGHT Can Deliver<\/h2>\n\n    <p>FIMSUS VS PLUS is a fundamentally different cable from the FISMIAN GroupLIGHT vertical reeling family. Where FISMIAN GroupLIGHT cables are optimised for high-speed vertical payout with lightweight cross-linked elastomer construction, FIMSUS VS PLUS is engineered for <strong>maximum mechanical brutality<\/strong>\u2014applications where the cable experiences <strong>simultaneous tensile and torsional loading<\/strong> under heavy-duty conditions that would destroy a FISMIAN GroupLIGHT cable within months. The Klaus Faber datasheet describes it explicitly: heavy-duty reeling rubber cable for power supply and signal transmission in applications with high mechanical stress, especially with simultaneous tensile and torsional load, suitable for cable drums for harbour cranes, container cranes, spreaders, conveyor systems, and handling machines <a class=\"src\" href=\"https:\/\/shop.faberkabel.de\/en\/Flexible-wires\/Rubber-insulated-cables\/Reeling-rubber-cable-URSUS-VS-PLUS\/\" target=\"_blank\" rel=\"noopener\">[Klaus Faber Shop \u2014 FIMSUS VS PLUS]<\/a>.<\/p>\n\n    <p>Every specification in the FIMSUS VS PLUS reflects this heavy-duty philosophy. The <strong>8,100 N dynamic tensile strength<\/strong> is the highest of any low-voltage vertical reel cable in the Klaus Faber catalogue\u201423% higher than the FISMIAN GroupLIGHT-VR&#8217;s 6,600 N. The <strong>4 kV test voltage<\/strong> exceeds the VR&#8217;s 3.5 kV and the VRDB&#8217;s 2.5 kV. The <strong>5GM5 polychloroprene neoprene outer sheath<\/strong> provides certified flame retardancy (IEC 60332-1-2), oil resistance (EN 60811-404), and ozone resistance (IEC 60811-403)\u2014a triple environmental certification that no FISMIAN GroupLIGHT cable carries. The <strong>tinned copper Class 5 conductors<\/strong> provide corrosion immunity in marine salt-spray environments. And the <strong>\u00b150\u00b0\/m quantified torsion rating<\/strong> is the only numerically specified torsion parameter in the entire vertical reel cable portfolio.<\/p>\n\n    <div class=\"note red\">\n      <div class=\"nt\">FIMSUS VS PLUS is NOT a FISMIAN GroupLIGHT Replacement<\/div>\n      <p>FIMSUS VS PLUS and FISMIAN GroupLIGHT-VR\/VRDB are <strong>different cable families<\/strong> for different applications. FIMSUS is heavier (1,890 vs. 1,850 kg\/km at comparable core count), has a wider bending radius (6\u00d7OD fixed vs. 4\u00d7OD), and operates at 240 m\/min (vs. 300 m\/min). Do not substitute one for the other without verifying the crane&#8217;s cable schedule, reel drum geometry, and speed requirements. FIMSUS is the correct specification when the application demands simultaneous high tensile AND high torsional loading\u2014conditions that are common on harbour cranes with long horizontal cable runs, conveyor systems with multi-directional cable paths, and spreader drum reels subject to severe fleet-angle torsion.<\/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>FIMSUS VS PLUS Technical Specifications (per Klaus Faber AG Datasheet dbl_ursus_vs_plus.pdf, Issue 04\/01\/2026)<\/caption>\n        <thead><tr><th>Parameter<\/th><th>Specification<\/th><th>Source \/ Standard<\/th><\/tr><\/thead>\n        <tbody>\n          <tr><td>Voltage Rating<\/td><td>Uo: <strong>1 kV<\/strong>.

For comparison: FISMIAN GroupLIGHT-VR 37\u00d72.5 = 4,700 N; FISMIAN GroupLIGHT-VR 56\u00d72.5 = 6,600 N; FISMIAN GroupLIGHT-VRDB 56\u00d72.5 = 6,600 N. The FIMSUS VS PLUS exceeds all of these by a significant margin, providing exceptional mechanical safety for applications with the highest tensile demands.<\/p>\n\n    <p>This 8,100 N rating specifically addresses the &#8220;simultaneous tensile and torsional load&#8221; condition described in the cable&#8217;s application statement. In practical crane operation, simultaneous loading occurs when a cable hangs vertically under gravity (tensile load) while the reel drum&#8217;s fleet-angle change imparts a twist to the cable at the departure point (torsional load). Standard cables designed for pure tensile or pure torsion fail when both forces act simultaneously\u2014the combined stress exceeds the single-axis design limit. The FIMSUS VS PLUS&#8217;s Kevlar core and synthetic braid torsion protection are co-engineered to share the combined load, maintaining structural integrity under dual-axis stress conditions that would overstress FISMIAN GroupLIGHT-class cables.<\/p>\n\n    <p>At 1,890 kg\/km net weight, the 8,100 N dynamic tensile supports approximately <strong>440 metres<\/strong> of cable self-weight under static conditions\u2014far exceeding any practical vertical suspension requirement.

This means the cable can withstand a rotational deformation of 50 degrees per metre of cable length in either direction without permanent deformation or performance degradation.

FIMSUS VS PLUS uses 5GM5 neoprene for its superior abrasion resistance, inherent flame retardancy, and certified oil\/ozone resistance\u2014properties critical in heavy-duty harbour crane applications where cables contact oily drum surfaces, run through confined fire-risk spaces, and operate in ozone-rich coastal atmospheres. The trade-off: 5GM5 neoprene is heavier and has a narrower moving temperature range (\u221230\u00b0C vs. \u221240\u00b0C).

If the insulation fails before the circuit breaker trips, the short circuit escalates to a phase-to-phase or phase-to-ground arc\u2014potentially causing cable fire, equipment damage, and worker injury. The 250\u00b0C rating provides the thermal margin needed for reliable fault clearing in heavy-duty crane electrical systems with long cable runs and high fault currents.<\/p>\n\n  <\/section>\n\n  <!-- ===== S11 ===== -->\n  <section class=\"body\" id=\"s11\">\n    <h2>FIMSUS VS PLUS vs. FISMIAN GroupLIGHT-VR vs. FISMIAN GroupLIGHT-VRDB: When to Choose Each<\/h2>\n\n    <div class=\"tw\">\n      <table>\n        <caption>Complete Vertical Reel Cable Comparison \u2014 Heavy-Duty vs. High-Speed<\/caption>\n        <thead><tr><th>Attribute<\/th><th>FIMSUS VS PLUS<\/th><th>FISMIAN GroupLIGHT-VR<\/th><th>FISMIAN GroupLIGHT-VRDB<\/th><\/tr><\/thead>\n        <tbody>\n          <tr><td>Engineering Philosophy<\/td><td><strong>Maximum mechanical strength<\/strong><\/td><td>Balanced performance<\/td><td>Tightest bending radius<\/td><\/tr>\n          <tr><td>Test Voltage<\/td><td><strong>4 kV (highest)<\/strong><\/td><td>3.5 kV<\/td><td>2.5 kV<\/td><\/tr>\n          <tr><td>Dynamic Tensile<\/td><td><strong>8,100 N (highest)<\/strong><\/td><td>6,600 N<\/td><td>6,600 N<\/td><\/tr>\n          <tr><td>Torsion Rating<\/td><td><strong>\u00b150\u00b0\/m (quantified)<\/strong><\/td><td>Aramid braid (qualitative)<\/td><td>Aramid braid (qualitative)<\/td><\/tr>\n          <tr><td>Conductor<\/td><td><strong>Tinned copper Class 5<\/strong><\/td><td>Bare copper Class 6<\/td><td>Bare copper Class 6<\/td><\/tr>\n          <tr><td>Outer Sheath<\/td><td><strong>5GM5 neoprene (toughest)<\/strong><\/td><td>Cross-linked elastomer<\/td><td>Cross-linked elastomer<\/td><\/tr>\n          <tr><td>Flame Retardant<\/td><td><strong>Yes \u2014 IEC 60332-1-2<\/strong><\/td><td>Not certified<\/td><td>Not certified<\/td><\/tr>\n          <tr><td>Oil Resistant<\/td><td><strong>Yes \u2014 EN 60811-404<\/strong><\/td><td>Not certified<\/td><td>Not certified<\/td><\/tr>\n          <tr><td>Ozone Resistant<\/td><td><strong>Yes \u2014 IEC 60811-403<\/strong><\/td><td>Not certified<\/td><td>Not certified<\/td><\/tr>\n          <tr><td>Fixed Temperature<\/td><td><strong>\u221250\u00b0C (coldest)<\/strong><\/td><td>\u221240\u00b0C<\/td><td>\u221240\u00b0C<\/td><\/tr>\n          <tr><td>Moving Temperature<\/td><td>\u221230\u00b0C<\/td><td><strong>\u221240\u00b0C (coldest)<\/strong><\/td><td>\u221230\u00b0C<\/td><\/tr>\n          <tr><td>Short-Circuit Temp<\/td><td><strong>250\u00b0C<\/strong><\/td><td>Not specified<\/td><td>Not specified<\/td><\/tr>\n          <tr><td>Protective Conductor<\/td><td><strong>Yes (green-yellow)<\/strong><\/td><td>No<\/td><td>No<\/td><\/tr>\n          <tr><td>Spreader Speed<\/td><td>240 m\/min<\/td><td><strong>300 m\/min (fastest)<\/strong><\/td><td><strong>300 m\/min<\/strong><\/td><\/tr>\n          <tr><td>Fixed Bending<\/td><td>6\u00d7OD<\/td><td><strong>4\u00d7OD (tightest)<\/strong><\/td><td>4\u00d7OD<\/td><\/tr>\n          <tr><td>Moving Bending<\/td><td>Per VDE 0298-3<\/td><td>8\u00d7OD<\/td><td><strong>7\u00d7OD (tightest)<\/strong><\/td><\/tr>\n        <\/tbody>\n      <\/table>\n    <\/div>\n\n    <p><strong>Choose FIMSUS VS PLUS<\/strong> when: the crane subjects the cable to simultaneous tensile and torsional loading; certified flame\/oil\/ozone resistance is required; the application needs a protective conductor (earthing); or the crane&#8217;s fault current requires 250\u00b0C short-circuit survival.

For heavy-duty reeling cables designed for simultaneous tensile and torsional loading, the dynamic rating is the critical design parameter\u2014it represents the cable&#8217;s ability to survive the combined instantaneous forces during aggressive reel acceleration, emergency braking, and snagging events. The permanent (static) tensile is typically lower. Contact Feichun&#8217;s engineering team for the specific Fzp value if required for your static suspension calculation.<\/p>\n\n    <h3>What is CAS 85535-85-9 in the REACH declaration?<\/h3>\n    <p>CAS 85535-85-9 identifies <strong>short-chain chlorinated paraffins (SCCPs)<\/strong>\u2014a plasticizer used in rubber compound formulations for flexibility and flame retardancy. SCCPs are listed on the EU REACH candidate list (Regulation EC 1907\/2006) as substances of very high concern (SVHC). The FIMSUS VS PLUS contains &gt;0.1% of this substance. This REACH declaration triggers supply-chain communication obligations per Article 33 of the REACH Regulation. For SCCP-free alternatives, contact Feichun&#8217;s engineering team\u2014modern rubber formulations using alternative plasticizers can achieve equivalent performance without SCCPs.<\/p>\n\n    <h3>Can FIMSUS VS PLUS replace the FIMSUS VS (non-PLUS)?<\/h3>\n    <p>The FIMSUS VS (non-PLUS) is described by Klaus Faber as a reeling cable for very high mechanical stresses, heavy-duty conditions, abrasion and crushing, typically used in cable winding reels for harbour cranes, container cranes, conveyors, and handling machines for vertical reeling applications <a class=\"src\" href=\"https:\/\/shop.faberkabel.de\/en\/Flexible-wires\/Rubber-insulated-cables\/Rubber-reeling-cable-URSUS-VS-0-6-1kV\/\" target=\"_blank\" rel=\"noopener\">[Klaus Faber Shop \u2014 FIMSUS VS]<\/a>. The VS PLUS adds enhanced tensile and torsional ratings. In most cases, the VS PLUS can replace the VS with improved performance, but verify the specific configuration (core count, cross-section) and bending radius requirements before substituting.<\/p>\n\n    <h3>Why 240 m\/min instead of 300 m\/min like FISMIAN GroupLIGHT?<\/h3>\n    <p>The 5GM5 neoprene sheath is thicker and stiffer than cross-linked elastomer, creating higher bending stiffness at the reel drum departure point. At 300 m\/min, this increased stiffness would generate excessive heat at the bending point during continuous high-speed cycling. The 240 m\/min rating ensures the sheath temperature remains within the +80\u00b0C moving limit during sustained reeling operation. For most harbour crane and conveyor applications, 240 m\/min is sufficient\u2014the FIMSUS VS PLUS is specified where mechanical ruggedness outweighs raw speed.<\/p>\n\n  <\/section>\n\n  <!-- ===== S14 ===== -->\n  <section class=\"refs\" id=\"s14\">\n    <h2>References &amp;
