堆垛机用扁平电缆技术对比：耐克森 RHEYFLAT®-T（集成悬挂装置）与 (N)TSFLCGEWÖU（外部应力释放）—— 面向自动化立体仓库（AS/RS）的工程分析
1. Introduction / 概述
Stacker cranes (Regalbediengeräte, RBG) are the core material-handling machines inside automated storage and retrieval systems (AS/RS). Operating within narrow aisles at heights that can exceed 40 m and horizontal travel speeds beyond 4 m/s, these machines demand flat cables that combine high-cycle bending endurance, precise positional tracking via integrated fibre optics, and robust EMC screening — all while supporting their own weight over vertical cable drops of 30 m or more.
堆垛机（Regalbediengeräte, RBG）是自动化立体仓库（AS/RS）的核心物料搬运设备。在窄巷道内运行，高度可超过 40 米，水平行进速度超过 4 m/s，这些设备对扁平电缆提出了极高要求：高周期弯曲耐久性、通过集成光纤实现精确位置追踪、以及可靠的 EMC 屏蔽 —— 同时还需承受 30 米以上垂直电缆自重。
Two dominant cable architectures compete for this demanding application: the Nexans RHEYFLAT®-T, which belongs to the RHEYFIRM(RS)-FLAT family and features an integrated suspension unit that makes the cable structurally self-supporting; and the generic DIN-designation (N)TSFLCGEWÖU (commercially known as Prysmian PROTOLON(FL) or equivalent), which relies on an external strain-relief clamp to manage tensile loads at the suspension point. This article provides a systematic comparison to help AS/RS integrators, warehouse automation engineers, and stacker crane OEMs make an informed selection.
两种主流电缆架构争夺这一苛刻应用场景：耐克森 RHEYFLAT®-T，属于 RHEYFIRM(RS)-FLAT 系列，配备集成悬挂装置使电缆具备结构自支撑能力；以及通用 DIN 型号 (N)TSFLCGEWÖU（商业名称为 Prysmian PROTOLON(FL) 或等效产品），依靠外部应力释放夹具管理悬挂点的拉伸载荷。本文为 AS/RS 集成商、仓库自动化工程师和堆垛机 OEM 提供系统对比。
2. Understanding the Cable Designations / 型号命名解析
The VDE letter-code system encodes every material and design element of the cable. Decoding (N)TSFLCGEWÖU reveals the cable’s entire construction philosophy. Meanwhile, the Nexans RHEYFLAT®-T trade name is built from RHEY (Nexans Hannover factory code) + FLAT (flat geometry) + T (Trommel / reel-capable with suspension). The “(RS)” in RHEYFIRM(RS)-FLAT further denotes the RHEYSTRIP easy-strip semi-conductive layer — a Nexans proprietary feature.
VDE 字母编码系统编码了电缆的每一种材料和设计元素。解码 (N)TSFLCGEWÖU 可揭示电缆的整体结构理念。耐克森 RHEYFLAT®-T 商标名由 RHEY（耐克森汉诺威工厂代码）+ FLAT（扁平几何）+ T（Trommel / 可卷绕带悬挂）构成。RHEYFIRM(RS)-FLAT 中的”(RS)”进一步表示 RHEYSTRIP 易剥离半导电层 —— 耐克森的专有技术。

3. Cable Construction & Architecture / 电缆结构与架构
3.1 Conductor / 导体
Both cables use flexible bare copper stranded conductors exceeding IEC 60228 / DIN VDE 0295 Class 5 requirements. As documented by CSE Distributors for the Nexans RHEYFIRM(RS)-FLAT range, Nexans conductors employ optimized S/Z stranding with rope-lay construction specifically engineered to maintain roundness and bending stability through millions of flex cycles. Prysmian’s PROTOLON(FL) datasheet similarly specifies Class 5 copper conductors, with typical cross-sections in the stacker-crane segment ranging from 3×25/25 mm² to 3×120/120 mm².
两种电缆均使用超过 IEC 60228 / DIN VDE 0295 Class 5 要求的柔性裸铜绞合导体。据 CSE Distributors 关于耐克森 RHEYFIRM(RS)-FLAT 系列的记录，耐克森导体采用优化的 S/Z 绞合绳绞结构，专门设计用于在数百万次弯曲循环中保持圆度和弯曲稳定性。Prysmian 的 PROTOLON(FL) 数据表同样指定 Class 5 铜导体，堆垛机应用的典型截面从 3×25/25 mm² 到 3×120/120 mm²。
3.2 Insulation System / 绝缘系统
A critical distinction lies in the insulation architecture. The Nexans RHEYFLAT®-T features a three-layer insulation system: an inner semi-conductive layer, a special EPDM-based “RHEYCLEAN” insulation compound (exceeding DIN VDE 0207 Part 20), and an outer semi-conductive “RHEYSTRIP” easy-strip layer. This tri-layer design — documented in the CSE Distributors product page for RHEYFIRM(RS)-FLAT — enables cleaner field terminations and more uniform electric-field distribution, reducing the risk of partial discharge at medium-voltage operating levels.
一个关键区别在于绝缘架构。耐克森 RHEYFLAT®-T 采用三层绝缘系统：内半导电层、基于 EPDM 的特殊”RHEYCLEAN”绝缘化合物（超过 DIN VDE 0207 Part 20）、以及外部”RHEYSTRIP”易剥离半导电层。据 CSE Distributors 产品页面记载，这种三层设计可实现更清洁的现场终端处理和更均匀的电场分布，降低中压运行水平下的局部放电风险。
The (N)TSFLCGEWÖU cable employs a comparable EPR (Ethylene Propylene Rubber) insulation system with semi-conductive layers, conforming to the 3GI3 compound specification per DIN VDE 0207 Part 20. The key material difference is that Nexans’ RHEYCLEAN compound is a proprietary formulation, while the generic specification permits any compliant EPR compound — introducing manufacturer-dependent quality variance.
(N)TSFLCGEWÖU 电缆采用类似的 EPR（乙丙橡胶）绝缘系统配以半导电层，符合 DIN VDE 0207 Part 20 的 3GI3 化合物规范。关键材料差异在于耐克森的 RHEYCLEAN 化合物为专有配方，而通用规格允许任何符合要求的 EPR 化合物 —— 这引入了制造商相关的质量差异。
3.3 Screening & EMC / 屏蔽与电磁兼容
Both cable types feature individual concentric screens on each power core, consisting of a mixed braid of tinned copper wires and high-tech polyamide yarn. This construction provides effective electromagnetic shielding critical in AS/RS environments where stacker cranes operate alongside sensitive PLC networks, profibus/profinet data lines, and encoder signals. The Nexans variant specifies this as a “concentric mixed braid of tinned copper wires and high-tech polyamid yarn” per the CSE product datasheet.
两种电缆类型均在每个动力芯上设有单独的同心屏蔽层，由镀锡铜丝和高科技聚酰胺纱线混合编织而成。这种结构提供有效的电磁屏蔽，在堆垛机与敏感 PLC 网络、profibus/profinet 数据线和编码器信号共存的 AS/RS 环境中至关重要。
3.4 Outer Sheath / 外护套
The Nexans cable uses a special chlorinated rubber compound, quality grade 5GM5 per DIN VDE 0207 Part 21, with a distinctive red outer color. The (N)TSFLCGEWÖU generic specification calls for an abrasion and tear-proof special rubber compound, minimum quality 5GM5 (for high mechanical stress) or 5GM3 (for standard stress), also per DIN VDE 0207. The Prysmian PROTOLON(FL) uses the higher 5GM5 grade as standard.
耐克森电缆使用特殊氯化橡胶化合物，按 DIN VDE 0207 Part 21 的 5GM5 质量等级，外观为独特的红色。(N)TSFLCGEWÖU 通用规格要求耐磨抗撕裂特种橡胶化合物，最低质量等级 5GM5（高机械应力）或 5GM3（标准应力）。Prysmian PROTOLON(FL) 标准采用更高的 5GM5 等级。

4. Electrical & Thermal Parameters / 电气与热参数
Both cables are medium-voltage rated, covering the voltage classes most commonly specified for stacker cranes in large AS/RS installations. The standard rated voltages available include 3.6/6 kV, 6/10 kV, 8.7/15 kV, and for large-scale port stacker-reclaimers, 12/20 kV and above. For typical indoor AS/RS stacker cranes with motor drives in the 30–150 kW range, the 3.6/6 kV or 6/10 kV ratings are most common.
两种电缆均为中压额定，涵盖大型 AS/RS 安装中堆垛机最常指定的电压等级。标准额定电压包括 3.6/6 kV、6/10 kV、8.7/15 kV，以及大型港口堆料机的 12/20 kV 及以上。对于电机驱动功率在 30–150 kW 范围内的典型室内 AS/RS 堆垛机，3.6/6 kV 或 6/10 kV 额定电压最为常见。
| Parameter / 参数 | RHEYFLAT®-T (Nexans) | (N)TSFLCGEWÖU (Prysmian / Generic) | Unit |
|---|---|---|---|

The RHEYSTRIP tri-layer insulation system of the Nexans RHEYFLAT®-T is specifically designed to minimize partial discharge (PD) activity at cable termination points. In stacker-crane applications where cable terminations may be located at the top of 30+ meter mast assemblies — subject to vibration and thermal cycling — reduced PD onset voltage translates directly into longer insulation service life and fewer unexpected outages in 24/7 AS/RS operations.
耐克森 RHEYFLAT®-T 的 RHEYSTRIP 三层绝缘系统专门设计以最小化电缆终端处的局部放电（PD）活动。在堆垛机应用中，电缆终端可能位于 30 米以上桅杆组件顶部 —— 承受振动和热循环 —— 降低 PD 起始电压直接意味着更长的绝缘使用寿命和 24/7 AS/RS 运行中更少的意外停机。
5. Mechanical & Motion Performance / 机械与运动性能
Stacker cranes impose a unique mechanical stress profile on flat cables: primarily single-plane bending (as the cable drapes from mast top to the moving carriage), combined with significant static and dynamic tensile loads from the cable’s own weight during high-speed vertical traversals. Unlike festoon-only applications, the cable must also run over guide rollers — creating localized compressive and shear forces at each contact point.
堆垛机对扁平电缆施加独特的机械应力特征：主要为单平面弯曲（电缆从桅杆顶部悬垂至移动载具），同时在高速垂直运动过程中承受来自电缆自重的显著静态和动态拉伸载荷。与纯滑触线应用不同，电缆还必须通过导向滚轮运行 —— 在每个接触点产生局部压缩和剪切力。

6. The Core Differentiator: Integrated Suspension Unit vs. External Strain Relief / 核心差异：集成悬挂装置与外部应力释放
This is the most consequential engineering difference between the two cable solutions and the primary decision factor for stacker-crane applications.
这是两种电缆方案之间最关键的工程差异，也是堆垛机应用中的首要决策因素。
6.1 RHEYFLAT®-T: Integrated Suspension Unit / 集成悬挂装置
The Nexans RHEYFLAT®-T incorporates a factory-integrated mechanical suspension element within the cable structure itself. This means the tensile load path from the suspension point (typically a bracket at the top of the stacker-crane mast) passes through a dedicated load-bearing member inside the cable — not through the conductors or insulation. The advantages of this approach are significant for stacker-crane duty: the cable is structurally self-supporting over long vertical drops without external hardware at the suspension point; the risk of conductor damage from concentrated mechanical stress at the clamp interface is eliminated; installation is simplified because no separate strain-relief bracket or clamp assembly is required; and the cable can be cut to length and re-suspended without specialized clamping tools.
耐克森 RHEYFLAT®-T 在电缆结构内部集成了工厂预制的机械悬挂元件。这意味着从悬挂点（通常是堆垛机桅杆顶部的支架）传递的拉伸载荷通过电缆内部的专用承载构件 —— 而非通过导体或绝缘层。这种方法对堆垛机工况有显著优势：电缆在长距离垂直悬垂时无需悬挂点外部硬件即可实现结构自支撑；消除了夹具接口处集中机械应力导致导体损坏的风险；安装简化，无需单独的应力释放支架或夹具组件；电缆可按长度切割并重新悬挂，无需专用夹紧工具。
6.2 (N)TSFLCGEWÖU: External Strain Relief / 外部应力释放
The generic (N)TSFLCGEWÖU cable requires a separately-sourced and field-installed external strain-relief clamp at each suspension and termination point. These clamps — typically steel or aluminium bracket assemblies with friction-grip surfaces — transfer the cable’s gravitational tensile load from the outer sheath to the support structure. While proven and reliable when correctly specified and installed, this approach introduces several considerations for stacker-crane duty: the clamp must be correctly matched to the cable’s flat dimensions (height × width); over-tightening can deform the cable cross-section and damage the semi-conductive insulation layers; under-tightening allows cable slippage under dynamic acceleration loads; and each clamp point becomes a scheduled maintenance inspection item per DIN VDE 0298 Part 3 installation guidelines.
通用 (N)TSFLCGEWÖU 电缆需要在每个悬挂和终端点单独采购并现场安装外部应力释放夹具。这些夹具 —— 通常为带摩擦夹紧面的钢或铝支架组件 —— 将电缆的重力拉伸载荷从外护套传递到支撑结构。虽然在正确选型和安装时可靠，但在堆垛机工况中需考虑几点：夹具必须正确匹配电缆扁平尺寸；过度拧紧可能变形电缆截面并损坏半导电绝缘层；拧紧不足在动态加速载荷下可能导致电缆滑移；每个夹具点按 DIN VDE 0298 Part 3 安装指南成为定期维护检查项目。
| Criteria / 评估维度 | Integrated Suspension (RHEYFLAT®-T) | External Strain Relief ((N)TSFLCGEWÖU) |
|---|---|---|
| Load Path | Internal load-bearing member | External clamp → outer sheath |
| Installation Complexity | Low — plug-and-hang | Medium — requires clamp selection, torque spec |
| Conductor Stress at Clamp | Near-zero (load bypasses conductors) | Risk of indirect stress via sheath compression |
| Maintenance Requirement | Minimal — no clamp to inspect | Periodic clamp torque check per VDE 0298-3 |
| Cable Shortening / Re-termination | Cut and re-suspend — simple | Must re-clamp with correct torque |
| Cost — Cable | Higher (integrated hardware) | Lower (cable only) |
| Cost — Ancillary Hardware | Included | Separate procurement of clamp kits |
| Total Installed Cost (typical) | Comparable or lower for >25 m drops | Comparable or lower for <15 m drops |
| Best For / 最佳场景 | Tall AS/RS (>20 m), 24/7 operation | Shorter stacker cranes, cost-sensitive projects |
| Analysis based on CSE Distributors[4]; Prysmian Crane Cables general catalog[7]; Conductix-Wampfler installation guidelines[8] | ||
In high-cycle stacker-crane operation (5,000+ storage/retrieval cycles per day), an improperly maintained external strain-relief clamp can gradually loosen due to vibration-induced micro-movements of the flat cable within the clamp jaw. Field reports from AS/RS integrators document cases where cable slippage of as little as 5–10 mm at the mast-top suspension point caused progressive conductor fatigue at the termination box — leading to unplanned downtime in 24/7 distribution center operations. The integrated suspension approach of the RHEYFLAT®-T eliminates this failure mode entirely.
在高循环堆垛机运行中（每天 5,000 次以上存取），维护不当的外部应力释放夹具可能因扁平电缆在夹口内的振动微位移而逐渐松动。AS/RS 集成商的现场报告记录了在桅杆顶部悬挂点电缆仅 5-10 mm 的滑移即导致终端盒处导体逐渐疲劳的案例 —— 导致 24/7 配送中心运营的计划外停机。RHEYFLAT®-T 的集成悬挂方法完全消除了此故障模式。

8. Application Scenario Analysis / 应用场景分析
8.1 High-Bay AS/RS Warehouses (>20 m mast height) / 高架 AS/RS 仓库
For high-bay stacker cranes operating in automated distribution centers, cold-storage facilities, and manufacturing buffer warehouses with mast heights exceeding 20 m, the Nexans RHEYFLAT®-T with integrated suspension unit offers a compelling total-cost-of-ownership advantage. The elimination of external strain-relief hardware reduces both the initial installation labor and ongoing maintenance burden. In 24/7 operations with 5,000–10,000 storage/retrieval cycles per day, the reduced risk of clamp-related failures translates into measurable improvements in system availability.
对于桅杆高度超过 20 米的自动化配送中心、冷库设施和制造缓冲仓库中的高架堆垛机，耐克森 RHEYFLAT®-T 配集成悬挂装置在总拥有成本方面具有显著优势。消除外部应力释放硬件降低了初始安装人工和持续维护负担。在每天 5,000-10,000 次存取循环的 24/7 运行中，降低夹具相关故障风险转化为可衡量的系统可用性提升。
8.2 Mini-Load & Shuttle Systems (<15 m mast height) / 小件货物及穿梭车系统
For smaller stacker cranes — mini-load systems, shuttle-based AS/RS, or light-load retrieval machines with mast heights under 15 m — the (N)TSFLCGEWÖU with external strain relief may represent the more cost-effective choice. The shorter cable drop produces lower static tensile loads, reducing the consequences of clamp-related issues. The cable-only procurement cost is typically lower, and the external clamp kits for small cross-sections are inexpensive and widely available from multiple suppliers.
对于较小的堆垛机 —— 小件货物系统、基于穿梭车的 AS/RS 或桅杆高度低于 15 米的轻载取件机 —— 配外部应力释放的 (N)TSFLCGEWÖU 可能是更具成本效益的选择。较短的电缆悬垂产生较低的静态拉伸载荷，降低了夹具相关问题的后果。
8.3 Stacker-Reclaimers & Port Equipment / 堆取料机与港口设备
For large stacker-reclaimers in bulk material handling (coal, iron ore, aggregates), both cable types at the 6/10 kV and 8.7/15 kV voltage ratings are well-proven. The Prysmian PROTOLON(FL) has documented installations on STS container cranes, RMG cranes, and stacker-reclaimers worldwide, with a design specifically validated for these applications through reversed bending and reeling tests. The Nexans RHEYFIRM(RS)-FLAT similarly lists stacker-reclaimers as a primary application.
对于散料搬运（煤、铁矿石、骨料）中的大型堆取料机，两种电缆在 6/10 kV 和 8.7/15 kV 电压等级下均有充分验证。Prysmian PROTOLON(FL) 在全球 STS 集装箱起重机、RMG 起重机和堆取料机上有记录的安装，其设计通过反向弯曲和卷绕测试专门验证。耐克森 RHEYFIRM(RS)-FLAT 同样将堆取料机列为主要应用。
8.4 VFD-Driven Systems with Fibre Optics / 变频驱动系统与光纤通信
Modern stacker cranes universally employ variable-frequency drives (VFDs). Both cable families offer fibre-optic variants (typically 6–24 fibres, single-mode 9/125 µm or multimode 50/125 µm and 62.5/125 µm) for simultaneous power and data transmission. As Prysmian notes, fibre-optic termination requires specialized skills and factory assembly is recommended. When specifying fibre-optic variants, ensure the stacker-crane OEM’s PLC system supports the fibre type (single-mode vs. multimode) and connector standard selected.
现代堆垛机普遍采用变频驱动（VFD）。两种电缆系列均提供光纤型号（通常 6-24 芯，单模 9/125 µm 或多模 50/125 µm 和 62.5/125 µm），实现电力和数据同步传输。如 Prysmian 指出，光纤终端需要专业技能，建议工厂组装。指定光纤型号时，确保堆垛机 OEM 的 PLC 系统支持所选光纤类型和连接器标准。

10. Conclusion & Recommendation / 结论与建议
The choice between Nexans RHEYFLAT®-T with integrated suspension and (N)TSFLCGEWÖU with external strain relief is ultimately determined by the specific stacker-crane installation parameters and the operator’s lifecycle cost priorities.
耐克森 RHEYFLAT®-T（集成悬挂）与 (N)TSFLCGEWÖU（外部应力释放）之间的选择最终取决于具体的堆垛机安装参数和运营商的全生命周期成本优先级。
Choose RHEYFLAT®-T when: the stacker crane operates in a high-bay AS/RS with mast heights exceeding 20 m; 24/7 operation demands maximum system availability with minimal scheduled maintenance; the site requires simplified installation (e.g., multiple stacker-crane aisles commissioned in rapid sequence during warehouse fit-out); enhanced partial-discharge performance is required at medium-voltage terminations subject to vibration; or the end-user has standardized on Nexans for lifecycle warranty consistency.
选择 RHEYFLAT®-T 的情形： 堆垛机在桅杆高度超过 20 米的高架 AS/RS 中运行；24/7 运行要求最大系统可用性和最少定期维护；现场需要简化安装；中压终端在振动条件下需要增强的局部放电性能；或终端用户已标准化使用耐克森。
