Nexans (N)TSCGEWTOEUS Equivalent: VDE 0250 Part 813 Reeling Cables
An engineering reference for specifying engineers, OEM cable approvers, and procurement teams working with reeling drum cables under the German VDE 0250 Part 813 standard. This document presents the standards framework defining VDE 0250 Part 813 reeling cables, the construction architecture this standard mandates, the type test battery that qualifies a cable to the standard, and the engineering basis on which Anhui Feichun Special Cable Co., Ltd. (安徽飞纯特种电缆有限公司) supplies VDE 0250 Part 813-compliant reeling cable as a direct equivalent to the Nexans (N)TSCGEWTOEUS family.
Standard Scope and Engineering Intent
What VDE 0250 Part 813 Defines
VDE 0250 Part 813 is the German cable standard defining construction, performance, and testing requirements for reeling cables — that is, flexible cables specifically designed for repeated winding and unwinding on motorized cable drums (reeling drums) installed on cranes, mining shovels, draglines, container handling equipment, port equipment, and similar mobile or relocatable machinery. 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.
Reeling drum service imposes a specific failure mode on cables: each reeling cycle subjects every section of cable to a defined sequence of mechanical events — 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.
VDE 0250 Part 813 applies to: 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 — including the characteristic reeling fatigue test — by which a cable is qualified as suitable for reeling drum service.
Distinguishing Reeling Cables from Trailing Cables
A 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. Trailing cables 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.
Reeling cables, 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 — 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.
The (N)TSCGEWTOEUS designation includes the “T” (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 — particularly surface mining shovels with cable reels and port crane reeling drums — 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.
Construction Requirements per VDE 0250 Part 813
The Construction Architecture VDE 0250 Part 813 Requires
VDE 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. Compliance at every layer is required for full standard qualification; partial compliance produces a cable that is suitable for some service but fails the VDE 0250-813 acceptance test at the omitted requirement.

The Reeling Fatigue Test — Defining Acceptance Criterion
The VDE 0250 Part 813 Reeling Fatigue Test
The reeling fatigue test is the centerpiece of VDE 0250 Part 813 qualification and the test that distinguishes a true reeling cable from a flexible cable that happens to be marketed for reeling service. The test subjects a representative cable sample to a defined number of reeling and unreeling cycles on a test drum sized to match the cable’s specified minimum dynamic bend radius, under controlled tension and ambient conditions, with electrical performance verification at the end of the cycle count.
3.1. Reeling Test Methodology
The 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 30–50 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 — 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:
- Repeated bending fatigue at the drum entry/exit point, where the cable transitions from straight to wrapped configuration once per reeling event;
- Layer-on-layer compression 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;
- Friction and chafing between adjacent turns and between cable and drum flange surfaces during reeling transitions;
- Tension cycling as the cable alternates between high-tension wound state and low-tension unwound state.
At 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 × U₀) 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.
3.2. Reeling Test Result Interpretation
| Cycle Count Achieved | Service Life Implication | Application Suitability | Standard Class |
|---|---|---|---|
| < 25,000 cycles | Inadequate for reeling service | Non-reeling applications only | Fails VDE 0250-813 |
| 25,000 – 50,000 cycles | Marginal for reeling service | Light-duty reeling, low cycle frequency | Below VDE 0250-813 minimum |
| 50,000 – 100,000 cycles | Standard reeling service qualification | Mining shovels, dragline, general industrial reeling | VDE 0250-813 standard class |
| 100,000 – 200,000 cycles | High-cycle reeling service | Port cranes, container handling, intensive cycling | VDE 0250-813 enhanced class |
| > 200,000 cycles | Premium reeling service | Ship-to-shore cranes, RMG/RTG cranes, automated terminals | Premium / project-qualified |
Anhui Feichun’s TSCGEWTOEUS-EQ series is qualified to the VDE 0250-813 standard class as the production baseline (≥ 50,000 cycles), with enhanced class qualification (≥ 100,000 cycles) available as a specified option for port crane and high-cycle applications. Type test reports documenting reeling cycle count, post-test electrical withstand performance, and post-test mechanical inspection results are available to qualified buyers under appropriate confidentiality. Where applications require qualification beyond standard class — for example, automated container terminal applications targeting 250,000+ cycles — Feichun supports the extended type testing through the witnessed qualification program.
Electrical Performance Specification
Electrical Performance Under VDE 0250 Part 813
Electrical performance requirements for VDE 0250-813 cables align with the broader IEC 60502-1 (low voltage) and IEC 60502-2 (medium voltage) framework, with specific reeling-cable considerations applied through reduced ampacity factors (recognizing the heat dissipation impact of cables wound on drums) and tighter partial discharge limits (recognizing that mechanical bending stress can initiate partial discharge at construction discontinuities).
4.1. Voltage Class and Withstand Performance
| Voltage Class U₀/U (U_m) | AC Withstand (5 min) | Impulse Withstand (1.2/50 µs) | Insulation Resistance (20°C) |
|---|---|---|---|
| 0.6/1 kV (1.2) | 3.5 kV | — | ≥ 10⁴ MΩ·km |
| 1.8/3 kV (3.6) | 10.5 kV | 40 kV | ≥ 10⁴ MΩ·km |
| 3.6/6 kV (7.2) | 21 kV | 60 kV | ≥ 10⁴ MΩ·km |
| 6/10 kV (12) | 35 kV | 95 kV | ≥ 10⁴ MΩ·km |
4.2. Partial Discharge Performance
Partial 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.
| PD Acceptance Criterion | Test Voltage | VDE Limit | Feichun Result |
|---|---|---|---|
| PD inception voltage | Increasing voltage to detect first PD | ≥ 1.5 × U₀ | ≥ 2.0 × U₀ typical |
| PD extinction voltage | Decreasing voltage to extinguish PD | ≥ 1.5 × U₀ | ≥ 1.7 × U₀ typical |
| PD magnitude at 1.5 × U₀ | Hold voltage, measure pC | ≤ 10 pC | ≤ 5 pC typical |
| PD after reeling fatigue | Re-test post-cycle | ≤ 10 pC at 1.5 × U₀ | ≤ 8 pC typical |
4.3. Reeling Service Ampacity Derating
A 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.
| Number of Layers on Drum | Derating Factor (typical) | Effective Ampacity vs Free-Air Rating | Application Note |
|---|---|---|---|
| 1 layer | 0.85 | 85% of free-air rating | Single-layer drum or fully unreeled |
| 2 layers | 0.65 | 65% of free-air rating | Light-duty reel, partial wound state |
| 3 layers | 0.45 | 45% of free-air rating | Standard mining shovel reel |
| 4 layers | 0.35 | 35% of free-air rating | Heavy-duty dragline, intensive port crane |
| 5+ layers | ≤ 0.30 | ≤ 30% of free-air rating | Project-specific thermal analysis required |
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 85–110 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.
Type Test Battery and Routine Test Coverage
The VDE 0250 Part 813 Test Battery
VDE 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. Type tests demonstrate that the design is capable of meeting the standard’s requirements; routine tests, executed on every manufactured length, demonstrate that each specific length actually does. The following section presents the complete type test scope and routine test coverage.
Electrical type tests verify the design’s voltage withstand, partial discharge characteristics, insulation resistance stability, and dielectric properties under temperature extremes. The battery includes: AC withstand voltage at 4 × U₀ for 4 hours (long-duration withstand); impulse withstand voltage at standard impulse levels (1.2/50 µs waveform); partial discharge measurement at 1.5 × U₀ and 2 × U₀; insulation resistance measurement at 20°C and at maximum operating temperature (90°C conductor); capacitance measurement; and tan δ (dielectric loss) measurement at rated voltage. Each test is executed per IEC 60230, IEC 60270, or IEC 60502-2 procedures with full documentation of test conditions, measured values, and pass/fail determination.
Mechanical type tests verify the design’s mechanical performance under reeling fatigue, impact, abrasion, and tear loading representative of service. The battery includes: reeling fatigue test (the central qualification test, ≥ 50,000 cycles per the standard); cold bend test at -40°C around mandrel of specified diameter; impact test using calibrated impact hammer at specified energy; abrasion test per Taber method (CS-17 abrasive, 1 kg load) or alternative drum abrasion test; tear propagation test on sheath material (ISO 34-1); tensile load test on completed cable construction; and compression test simulating layer-on-layer drum loading. Mechanical tests are executed on representative production cable samples; results are documented in the type test report with photographs and measured values.
Material type tests verify the insulation, semiconductive screen, and sheath compounds meet specification both at manufacture and after accelerated aging. The battery includes: tensile and elongation tests on insulation and sheath samples (per DIN 53504); accelerated thermal aging at 135°C for 168 hours followed by tensile and elongation retention measurement; hot-set test at 200°C verifying peroxide cure crosslinking; oil immersion test (IRM 902 oil, 70°C, 168 hours) with mechanical property retention measurement; ozone resistance test on rubber components; and water absorption test. Each test verifies a specific compound property; collectively they confirm the materials are correctly formulated, correctly cured, and capable of long-term service performance.
Routine tests are executed on every manufactured length before shipment. The full routine test scope includes: conductor DC resistance measurement at 20°C (verifying conductor cross-section meets IEC 60228 requirement); AC voltage withstand at 4 × U₀ for 5 minutes (verifying insulation integrity); insulation resistance measurement at 500 V DC (target ≥ 10⁴ MΩ·km); partial discharge measurement at 1.5 × U₀ for medium-voltage cables; sheath spark test for sheath integrity verification; dimensional verification (overall diameter, conductor cross-section, insulation thickness, sheath thickness, conductor centering); and visual inspection. Each length ships with a Routine Test Certificate documenting actual measured values traceable to the specific length and to the underlying type test reports.
Application Coverage and Procurement
Where VDE 0250-813 Cables Serve
VDE 0250 Part 813 reeling cables serve a wide range of applications across mining, port handling, steel, and process industries. The unifying characteristic of all these applications is the presence of a motorized cable drum that winds and unwinds cable as the equipment moves; the differentiating characteristics are voltage class, conductor cross-section, environmental conditions, and cycle count. Feichun TSCGEWTOEUS-EQ series cables are supplied across all of these application categories under VDE 0250-813 qualification.

6.2. Specification Engagement Path
Procurement 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 — 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.
Specification development typically completes in 5–10 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 — port crane projects, automated terminal projects, mining OEM equipment qualification — the engineering team supports the witnessed type test program through a recognized testing laboratory at the buyer’s preference.
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’s specification requires additional documentation — flame propagation test results, smoke and acid gas release test results for restricted-ventilation applications, low-temperature qualification certificates — these are supplied as documented in the project specification.
Conclusion
Standards-Aligned Reeling Cable Engineering
VDE 0250 Part 813 reeling cables are engineered products defined by a specific standards framework — not generic flexible cables marketed for reeling service. The standard establishes the construction architecture (Class 5 or Class 6 fine-wire conductors, peroxide-cured EPR insulation with semiconductive screens at medium voltage, concentric tinned copper earth conductor, textile reinforcement, peroxide-cured CPE or CR sheath), the electrical performance requirements (voltage withstand, partial discharge, insulation resistance, drum-derated ampacity), and the qualification testing battery centered on the reeling fatigue test that distinguishes a true reeling cable from a flexible cable that nominally fits the duty.
The Nexans (N)TSCGEWTOEUS family is one widely-recognized commercial implementation of VDE 0250-813 cable; the Feichun TSCGEWTOEUS-EQ series is a directly equivalent implementation of the same standard, engineered to deliver matched form, fit, and function across the conductor cross-section range and voltage classes covered by the original product. The equivalence is grounded in the shared standards framework (the cables are not “similar” to each other but are both qualified to VDE 0250-813), in matched construction at every layer, in matched type test scope and acceptance criteria, and in routine test coverage on every manufactured length. Operators specifying VDE 0250-813 reeling cable can engage Feichun on the same standards basis they engage any qualified VDE 0250-813 supplier.
For VDE 0250-813 reeling cable specification, qualification documentation, sample cable supply for evaluation, or formal procurement engagement, contact the Feichun reeling cable engineering team. Initial engagement requires the application context (equipment type, drum specification, electrical load profile, ambient conditions) and the operator’s relevant specification or standard references (VDE 0250-813 by default, with operator-specific or OEM-specific specifications layered on as required). Specification consultation, cross-reference documentation, and technical proposal development are provided without charge for qualified procurement engagements. Production lead times for standard VDE 0250-813 specifications are typically 6–10 weeks from order confirmation; expedited delivery is available where production capacity allows.
