The nominal outer dimensions of the NGFLGÖU-J 4G16 flat rubber cable are 38.0 mm width × 13.0 mm thickness (approximately 1.50 inches × 0.51 inches). However, because industrial manufacturing is subject to tolerances, the practical specification range follows VDE 0250-809 standards and typically falls between 37.0–42.0 mm width and 12.5–14.0 mm thickness, depending on the manufacturer's rubber compound formulation and production control practices. This cable carries four cores of 16 mm² conductors each (including one green/yellow earth core), making it a 4G16 configuration rated for 300/500V continuous operation with a maximum test voltage of 3,000V. NGFLGÖU-J 4G16 扁形橡胶电缆的标称外部尺寸为**38.0 毫米宽 × 13.0 毫米厚**（约 1.50 英寸 × 0.51 英寸）。然而，因为工业制造受到公差的约束，实际规范范围遵循 VDE 0250-809 标准，通常在**37.0–42.0 毫米宽和 12.5–14.0 毫米厚**之间，取决于制造商的橡胶混合物配制和生产控制实践。这条电缆承载四个 16 毫米² 导体的芯（包括一个绿/黄接地芯），使其成为额定 300/500V 连续运行的 4G16 配置，最大测试电压为 3,000V。

NGFLGÖU-J 4G16 Flat Cable Dimensions: What is the Exact Width and Thickness?

The nominal width of a (N)TSFLCGEWÖU 4x120 0.6/1kV shielded flat trailing cable is approximately 91 mm (3.58 inches), with a tolerance window of ±3.5 mm producing a permissible range of 87.5–94.5 mm. The nominal thickness is approximately 27.5 mm (1.08 inches), with a tolerance window of ±1.5 mm producing a permissible range of 26.0–29.0 mm. The approximate total weight of this cable is 8,200 kg/km (5,500 lbs/1000 ft), with copper weight approximately 5,250 kg/km. It features four 120 mm² main power conductors rated for 321 amperes continuous operation at 30°C ambient, supplemented by individual copper braid shielding on each conductor for electromagnetic compatibility (EMC) with variable-frequency drives and other sensitive equipment. The distinction between width and thickness for flat cables differs fundamentally from round cable specifications because flat cables do not have a single outer diameter. Instead, engineers must manage two dimensions simultaneously, and these dimensions directly determine whether the cable will fit into festoon track systems, contact shoe assemblies, and guidance rail configurations commonly deployed in overhead crane systems and automated material handling equipment.

Indoor overhead cranes, gantry cranes, and material handling systems require specialized flat cables that can withstand constant flexing, bending, and mechanical stress while delivering reliable power and control signals.
