The standard is one of several parts within the larger VDE 0250 family covering rubber-insulated and polymer-insulated cables for power installations; Part 813 specifically addresses the unique mechanical demands of drum reeling service, which differ materially from the demands placed on stationary power cables, conventional trailing cables, or general-purpose flexible cables.\n<\/p>\n\n<p>\nReeling drum service imposes a specific failure mode on cables: each reeling cycle subjects every section of cable to a defined sequence of mechanical events \u2014 straightening as the cable pays out, controlled bending as it spirals onto the drum, layer-on-layer compression as successive turns load atop earlier turns, and repeated friction at layer transitions. A surface-mining shovel reel cable executing 4,000 reeling cycles per year, over a 5-year service expectation, sees 20,000 full mechanical fatigue cycles. A port container crane reel cable can exceed this by an order of magnitude. Cables not engineered specifically for this duty fail through conductor strand breakage at flex points, sheath fatigue cracking at bending zones, insulation displacement under compression, or layer-to-layer abrasion damage. VDE 0250 Part 813 exists to define the cable engineering response to this specific service environment.\n<\/p>\n\n<div class=\"definition-block\">\n  <span class=\"definition-tag\">SCOPE DEFINITION<\/span>\n  <p>\n    <strong>VDE 0250 Part 813 applies to:<\/strong> flexible cables with rubber insulation (predominantly EPR \/ EPDM) and rubber outer sheath (CPE, CR\/Neoprene), Class 5 or Class 6 fine-wire stranded copper conductors, voltage classes from 0.6\/1 kV through 6\/10 kV, intended for service on motorized cable drums where the cable experiences repeated reeling and unreeling cycles under defined tensile, bending, and compressive loading conditions. The standard establishes minimum conductor stranding fineness, insulation and sheath compound performance criteria, dimensional construction requirements, and the type test battery \u2014 including the characteristic reeling fatigue test \u2014 by which a cable is qualified as suitable for reeling drum service.\n  <\/p>\n<\/div>\n\n<h3>Distinguishing Reeling Cables from Trailing Cables<\/h3>\n\n<p>\nA frequent source of specification confusion in mining and crane procurement is the distinction between trailing cables and reeling cables. Both terms are sometimes used interchangeably in vendor literature, but the engineering basis is different. <strong>Trailing cables<\/strong> are dragged behind moving equipment along the ground; their primary mechanical demands are abrasion, impact from rocks and obstacles, longitudinal tension under drag loading, and exposure to ground hazards including spillage of hydraulic oil, diesel fuel, and process water. Standards such as VDE 0250 Part 812 (trailing cables) and Type SHD-GC under ICEA S-75-381 in the Americas address this duty.\n<\/p>\n\n<p>\n<strong>Reeling cables<\/strong>, in contrast, are wound onto and unwound from a powered drum; their primary mechanical demands are repeated bending fatigue, layer-on-layer compression, and friction during reeling transitions. While the cable may incidentally experience drag, abrasion, and impact, these are secondary considerations to the reeling duty itself. VDE 0250 Part 813 governs this duty. The Nexans (N)TSCGEWTOEUS family is engineered specifically as a reeling cable \u2014 the construction features (Class 6 conductor stranding for maximum flexibility, optimized insulation and sheath geometry for bending, textile reinforcement to resist tear propagation under bending stress) are reeling-cable-specific engineering choices. Specifying a trailing cable for a reeling application, or a reeling cable for a trailing application, can produce passable initial performance and premature failure as the wrong failure mode dominates.\n<\/p>\n\n<div class=\"callout callout-info\">\n  <div class=\"callout-title\">\u25a3 Engineering Note: Application-Driven Specification<\/div>\n  <p>\n    The (N)TSCGEWTOEUS designation includes the &#8220;T&#8221; (trailing) character within German cable nomenclature, which reflects the fact that VDE classification historically treated reeling and trailing cables within overlapping designation systems. Modern VDE 0250 Part 813 explicitly addresses reeling duty as the controlling design criterion. Many real-world applications \u2014 particularly surface mining shovels with cable reels and port crane reeling drums \u2014 combine elements of both duties. The (N)TSCGEWTOEUS construction is engineered to perform under both duties, with reeling fatigue resistance as the dominant design driver and trailing-cable mechanical robustness as the supporting envelope.\n  <\/p>\n<\/div>\n\n<div class=\"section-divider\">\n  <span class=\"section-num iec\">\u00a7 02<\/span>\n  <hr>\n  <span class=\"section-divider-label\">Construction Requirements per VDE 0250 Part 813<\/span>\n<\/div>\n\n<h2>The Construction Architecture VDE 0250 Part 813 Requires<\/h2>\n\n<p>\nVDE 0250 Part 813 prescribes specific construction requirements that distinguish a qualified reeling cable from a generic flexible power cable. These requirements operate at every layer of the cable construction: conductor, conductor screen (medium-voltage), insulation, insulation screen, concentric earth conductor, reinforcement layer, and outer sheath.

Reeling Test Methodology<\/h3>\n\n<p>\nThe reeling fatigue test replicates, in compressed laboratory time, the mechanical history a cable experiences over years of service on an actual reeling drum. The test cable sample (typically 30\u201350 metres of cable) is mounted on a test drum of specified diameter and reeled and unreeled at a controlled speed, with a tensioning system maintaining a defined back-tension on the cable as it spools. The cycle continues for the prescribed cycle count \u2014 50,000 cycles is the standard minimum for VDE 0250-813, with higher counts (100,000+ cycles) specified for premium classes and high-cycle applications such as port container cranes and steel mill ladle cars. Throughout the cycle, the cable is subject to:\n<\/p>\n\n<ul>\n  <li><strong>Repeated bending fatigue<\/strong> at the drum entry\/exit point, where the cable transitions from straight to wrapped configuration once per reeling event;<\/li>\n\n  <li><strong>Layer-on-layer compression<\/strong> as successive turns wrap atop earlier turns, with the bottom layers experiencing peak compressive load equal to the cumulative weight of all overlying turns plus tension forces;<\/li>\n\n  <li><strong>Friction and chafing<\/strong> between adjacent turns and between cable and drum flange surfaces during reeling transitions;<\/li>\n\n  <li><strong>Tension cycling<\/strong> as the cable alternates between high-tension wound state and low-tension unwound state.<\/li>\n<\/ul>\n\n<p>\nAt the end of the cycle count, the test cable is inspected for visible damage (sheath cracking, insulation displacement, conductor exposure), then subjected to AC voltage withstand testing at four times rated voltage (4 \u00d7 U\u2080) for five minutes. Pass criteria require no electrical breakdown, no flashover, no insulation puncture, and no observable mechanical damage that would compromise continued service. Cables that pass the reeling fatigue test at the prescribed cycle count are qualified for VDE 0250-813 reeling service; cables that fail are not.\n<\/p>\n\n<h3>3.2.

Partial Discharge Performance<\/h3>\n\n<p>\nPartial discharge measurement is a particularly sensitive indicator of cable construction quality in reeling service, because the repeated bending the cable experiences in service can amplify the electrical stress at any minor construction discontinuity. A cable that meets partial discharge limits at manufacture but has marginal screen-insulation interface quality will see partial discharge inception migrate to lower voltage levels as the cable ages under reeling stress, eventually reaching service voltage and producing accelerated insulation aging at the discharge site. VDE 0250-813 cables therefore require not only acceptance partial discharge measurements but extinction voltage performance demonstrating that any partial discharge initiated at elevated voltage extinguishes at voltages safely above operating voltage.\n<\/p>\n\n<table class=\"spec-table\">\n  <thead>\n    <tr>\n      <th>PD Acceptance Criterion<\/th>\n      <th>Test Voltage<\/th>\n      <th>VDE Limit<\/th>\n      <th>Feichun Result<\/th>\n    <\/tr>\n  <\/thead>\n  <tbody>\n    <tr>\n      <td><strong>PD inception voltage<\/strong><\/td>\n      <td>Increasing voltage to detect first PD<\/td>\n      <td>\u2265 1.5 \u00d7 U\u2080<\/td>\n      <td class=\"match\">\u2265 2.0 \u00d7 U\u2080 typical<\/td>\n    <\/tr>\n    <tr>\n      <td><strong>PD extinction voltage<\/strong><\/td>\n      <td>Decreasing voltage to extinguish PD<\/td>\n      <td>\u2265 1.5 \u00d7 U\u2080<\/td>\n      <td class=\"match\">\u2265 1.7 \u00d7 U\u2080 typical<\/td>\n    <\/tr>\n    <tr>\n      <td><strong>PD magnitude at 1.5 \u00d7 U\u2080<\/strong><\/td>\n      <td>Hold voltage, measure pC<\/td>\n      <td>\u2264 10 pC<\/td>\n      <td class=\"match\">\u2264 5 pC typical<\/td>\n    <\/tr>\n    <tr>\n      <td><strong>PD after reeling fatigue<\/strong><\/td>\n      <td>Re-test post-cycle<\/td>\n      <td>\u2264 10 pC at 1.5 \u00d7 U\u2080<\/td>\n      <td class=\"match\">\u2264 8 pC typical<\/td>\n    <\/tr>\n  <\/tbody>\n<\/table>\n\n<h3>4.3. Reeling Service Ampacity Derating<\/h3>\n\n<p>\nA cable wound on a drum cannot dissipate heat as readily as a cable run in free air or in a cable tray; heat generated in the inner layers of a wound drum must travel through multiple layers of cable before reaching the surface where it can be dissipated. VDE 0250-813 (and aligned IEC standards) account for this through ampacity derating factors applied based on the number of layers wound on the drum. The derating recognizes that the limiting condition for ampacity is the conductor temperature at the bottom (innermost) layer of the wound drum, which is the layer with the worst heat dissipation path.\n<\/p>\n\n<table class=\"spec-table\">\n  <thead>\n    <tr>\n      <th>Number of Layers on Drum<\/th>\n      <th>Derating Factor (typical)<\/th>\n      <th>Effective Ampacity vs Free-Air Rating<\/th>\n      <th>Application Note<\/th>\n    <\/tr>\n  <\/thead>\n  <tbody>\n    <tr>\n      <td class=\"code\">1 layer<\/td>\n      <td class=\"value-vde\">0.85<\/td>\n      <td>85% of free-air rating<\/td>\n      <td>Single-layer drum or fully unreeled<\/td>\n    <\/tr>\n    <tr>\n      <td class=\"code\">2 layers<\/td>\n      <td class=\"value-vde\">0.65<\/td>\n      <td>65% of free-air rating<\/td>\n      <td>Light-duty reel, partial wound state<\/td>\n    <\/tr>\n    <tr>\n      <td class=\"code\">3 layers<\/td>\n      <td class=\"value-vde\">0.45<\/td>\n      <td>45% of free-air rating<\/td>\n      <td>Standard mining shovel reel<\/td>\n    <\/tr>\n    <tr>\n      <td class=\"code\">4 layers<\/td>\n      <td class=\"value-vde\">0.35<\/td>\n      <td>35% of free-air rating<\/td>\n      <td>Heavy-duty dragline, intensive port crane<\/td>\n    <\/tr>\n    <tr>\n      <td class=\"code\">5+ layers<\/td>\n      <td class=\"value-vde\">\u2264 0.30<\/td>\n      <td>\u2264 30% of free-air rating<\/td>\n      <td>Project-specific thermal analysis required<\/td>\n    <\/tr>\n  <\/tbody>\n<\/table>\n\n<div class=\"callout callout-warn\">\n  <div class=\"callout-title\">\u25a3 Critical Specification Point \u2014 Ampacity in Reeling Service<\/div>\n  <p>\n    The single most common ampacity specification error in reeling cable applications is calculating the cable cross-section based on free-air ampacity tables and ignoring the layer derating. A cable specified for 250 A free-air ampacity may deliver only 85\u2013110 A continuous capacity when wound on a 4-layer drum without exceeding insulation temperature limits. Applications experiencing intermittent overload, repeated motor starting current, or partial unreeling during peak load operation can mask the derating problem until a heating event reveals it through accelerated insulation aging or, in severe cases, thermal failure of the innermost layer. The correct approach is to size the cable based on the worst-case wound configuration (typically the fully wound state at maximum continuous load), apply the appropriate VDE 0250-813 derating factor, and add a margin for transient thermal events. Feichun engineering supports this calculation as part of specification consultation; provide the reeling drum specification (number of layers, drum dimensions), continuous load profile, and ambient conditions, and the engineering team returns the recommended cross-section with full thermal analysis documentation.\n  <\/p>\n<\/div>\n\n<div class=\"section-divider\">\n  <span class=\"section-num test\">\u00a7 05<\/span>\n  <hr>\n  <span class=\"section-divider-label\">Type Test Battery and Routine Test Coverage<\/span>\n<\/div>\n\n<h2>The VDE 0250 Part 813 Test Battery<\/h2>\n\n<p>\nVDE 0250-813 qualification requires successful completion of a defined battery of type tests, executed once per cable design and re-executed when significant design changes occur.

Specification Engagement Path<\/h3>\n\n<p>\nProcurement engineers engaging Feichun for VDE 0250-813 reeling cable specification typically work through a structured specification path that captures all parameters required for engineered supply. The engagement begins with the application context \u2014 the equipment type, cable drum specification (drum diameter, number of layers, drum drive arrangement), continuous and peak electrical load, voltage system, and ambient operating conditions. From this context, the engineering team develops the cable specification covering voltage class, conductor cross-section (with drum-derated ampacity calculation), insulation and sheath material selection (with environmental adjustments where required), reinforcement specification, earth conductor configuration, and reeling cycle qualification class.\n<\/p>\n\n<p>\nSpecification development typically completes in 5\u201310 business days for standard configurations. The engineering output includes the proposed cable specification sheet, the cross-reference to applicable VDE\/IEC standards, the type test certificate references documenting the qualification basis, and the production lead time and pricing for the specified configuration. Where the application warrants third-party qualification \u2014 port crane projects, automated terminal projects, mining OEM equipment qualification \u2014 the engineering team supports the witnessed type test program through a recognized testing laboratory at the buyer&#8217;s preference.\n<\/p>\n\n<div class=\"callout callout-info\">\n  <div class=\"callout-title\">\u25a3 Documentation Available with Supply<\/div>\n  <p>\n    Each VDE 0250-813 cable supply from Feichun includes documentation supporting the qualification chain from standard reference to specific delivered length. Documentation includes: the type test certificate documenting design qualification against VDE 0250-813 (and applicable IEC, DIN, HD references); the routine test certificate documenting test results on the specific delivered length; the certificate of conformance referencing the ISO 9001 quality management system and the specific applicable product standards; the conductor metal mill test certificate (where required by buyer specification); and the dimensional inspection report. Where the buyer&#8217;s specification requires additional documentation \u2014 flame propagation test results, smoke and acid gas release test results for restricted-ventilation applications, low-temperature qualification certificates \u2014 these are supplied as documented in the project specification.\n  <\/p>\n<\/div>\n\n<div class=\"section-divider\">\n  <span class=\"section-num\">\u00a7 07<\/span>\n  <hr>\n  <span class=\"section-divider-label\">Conclusion<\/span>\n<\/div>\n\n<h2>Standards-Aligned Reeling Cable Engineering<\/h2>\n\n<p>\nVDE 0250 Part 813 reeling cables are engineered products defined by a specific standards framework \u2014 not generic flexible cables marketed for reeling service.
