4x4mm2 flexible cable is a 4-core power cable featuring four individual conductors, each with a \(4\text{mm}^2\) cross-sectional area, designed for high-power, multi-phase systems. It commonly features multi-strand copper conductors for high flexibility, suited for industrial machinery, 3-phase systems, and heavy-duty portable equipment, with an outer diameter often around 3.3 mm for single cores
