Examples of Common Part Numbers:

Among the most commonly used part numbers of Prysmian’s CORDAFLEX® (SMK) (N)SHTOEU cables, a wide variety of configurations are available to meet diverse industrial needs. For instance, models such as 12G2.5+3×2.5, with 12 power cores and 3 control cores of 2.5 mm², or 18G2.5+3×2.5, which includes 18 power cores alongside 3 control cores, are ideal choices for heavy-duty equipment requiring simultaneous power and control. In more specialized applications, models like 12G2.5+3×2.5+1P FO, which adds a fiber optic pair for data transmission, are suitable for systems that require both high-speed data and power transmission. Additionally, the 18G2.5+3×2.5+4×1.5 C variant, which includes 4 separate control cores of 1.5 mm², is used in precise and multifunctional control systems. The wide range of part numbers allows for optimized selection based on power demand and cable run length, while also integrating control, communication, and protective functionalities.
