1. Executive Summary: The Meaning of “F”
2. Comprehensive Breakdown of (N)TSFLCGEWÖU Designation
Understanding the full alphanumeric code is essential for verifying compliance with DIN VDE 0250 standards. Below is the detailed breakdown.
理解完整的字母数字代码对于验证是否符合 DIN VDE 0250 标准至关重要。以下是详细的解析。
| Symbol (符号) | Origin (源含义) | Technical Meaning (技术含义) |
|---|---|---|
| (N) | Normen (Standard) | Manufactured according to VDE standards (specifically VDE 0250). 按照VDE标准制造（特别是VDE 0250）。 |
| TS | Trossen (Trailing/Heavy) | Indicates a heavy-duty trailing or reeling cable design suitable for dynamic loads. 表示适用于动态负载的重型拖曳或卷盘电缆设计。 |
| F | Flach (Flat) | Flat construction (Parallel cores). This is the key identifier. 扁平结构（平行缆芯）。这是关键标识符。 |
| L | Leitung (Line/Type) | Often denotes the specific series type within the manufacturer’s range (e.g., Protolon) or Light-duty variants, though in MV flat cables it usually signifies the specific flat conductor arrangement. 通常表示制造商系列中的特定类型，或者在此类中压扁缆中指特定的扁平导体排列。 |
| C | Concentrical | Indicates the presence of a concentric copper screen (shield) to manage electrical fields. 表示存在同心铜屏蔽层以管理电场。 |
| G | Gummi (Rubber) | Insulation material is Rubber (typically High-Grade EPR based on 3GI3). 绝缘材料为橡胶（通常为基于3GI3的高级乙丙橡胶）。 |
| EW | Earth / Wirksam | Single-core screening with earth conductors, or field control layers. 单芯屏蔽带接地导体，或电场控制层。 |
| Ö | Ölbeständig | Oil-resistant outer sheath. 耐油外护套。 |
| U | Unflammable | Flame-retardant outer sheath (typically PCP or Chloroprene rubber 5GM3). 阻燃外护套（通常为氯丁橡胶 5GM3）。 |
3. Technical Advantages of the “F” (Flat) Design
A. Superior Bending Radius (优越的弯曲半径)
Flat cables are flexible in only one plane. This allows them to bend much more tightly than round cables of the same cross-sectional area. This is ideal for Festoon Systems where cables hang in loops.
- Flat Cable Bending Factor: Typically 3x to 5x cable thickness.
- Round Cable Bending Factor: Typically 6x to 15x cable diameter.
B. Stackability (可堆叠性)
In festoon cable trolleys, space is premium. Flat cables can be stacked directly on top of one another without the risk of “corkscrewing” (twisting) that plagues round cables. This allows for high-density power and data transmission in a compact footprint.
C. Thermal Dissipation (散热性能)
The “F” design provides a larger surface-area-to-volume ratio compared to round cables. This allows for better heat dissipation, which is crucial for Medium Voltage (MV) cables operating under continuous load in hot port environments.
4. Application Scenarios
| Machinery (机械设备) | Usage Context (使用环境) |
|---|---|
| Ship-to-Shore (STS) Cranes 岸桥起重机 | Used in the main power supply festoon systems for the trolley travel. High speed and high dynamic stress. 用于小车运行的主电源拖令系统。高速且高动态应力。 |
| Rubber Tyred Gantry (RTG) Cranes 轮胎式龙门吊 | Power supply for lateral movement where cable reels are not feasible due to space constraints. 由于空间限制无法使用电缆卷盘时的横向移动供电。 |
| Stacker Reclaimers 斗轮堆取料机 | Mining and bulk handling yards often utilize flat cables for the moving tripper cars. 矿山和散货堆场通常在移动卸料车上使用扁平电缆。 |
