trolley system cable

The nominal width of a (N)TSFLCGEWÖU 4×120 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.
