H05V-K flexible cable is a high-performance cable complying with IEC 60227 standard, with cross-sectional sizes ranging from 1.5mm² to 6mm² and a rated voltage of 300/500V. Due to its excellent flexibility and stable electrical performance, it is widely used in connection scenarios of electrical equipment that require frequent movement or bending. The model "H05V-K" clearly identifies its characteristics: "H" stands for Harmonized standard cable, "05" indicates a rated voltage of 300/500V, "V" refers to PVC insulation, and "K" indicates that it has a flexible structure, suitable for occasions with high requirements for cable flexibility such as handheld devices and small mobile machinery.​ In terms of specification parameters, cables with different cross-sectional sizes have significantly different current-carrying capacities, which can meet diverse power demand. The 1.5mm² cable has a current-carrying capacity of about 10-16A, suitable for connecting household appliances (such as vacuum cleaners, hair dryers) and small electric tools (such as electric drills, sanders); the 2.5mm² cable has a current-carrying capacity of 16-25A, which can be used for power supply of medium-sized electric tools (such as angle grinders, cutting machines) and office equipment (such as large printers, shredders); the 4mm² cable has a current-carrying capacity of about 25-32A, applicable to small mobile machinery (such as small conveyors, material hoists); the 6mm² cable has a current-carrying capacity of up to 32-40A, which can meet the power demand of larger power mobile equipment (such as small generators, portable water pumps). The cable has an insulation resistance of ≥100MΩ·km and passes the 2500V voltage withstand test (no breakdown for 1 minute), ensuring insulation reliability under normal working conditions. Its operating temperature range is -15℃ to 70℃, which can adapt to changes in different ambient temperatures.​ In terms of material and structure, the conductor is made of Class 5 copper, which is stranded by multiple fine copper wires, having extremely high flexibility. It can withstand frequent bending and twisting without breaking, greatly extending the service life of the cable in mobile use. The insulation layer is made of high-quality PVC material, which not only has good insulation performance, but also has oil resistance, moisture resistance and certain chemical corrosion resistance, and can work stably in humid environments with mild oil stains. The cable sheath is also made of PVC material, mostly in black or gray, with clear model, specification, standard logo and other information printed on the surface, facilitating identification and traceability. The overall structure is compact, and the layers are firmly combined, which can effectively resist external mechanical damage.​ Its characteristic uses are concentrated in fields requiring flexible connections. In homes and commercial places, it can be used as power connecting lines for household appliances such as vacuum cleaners, electric irons, microwave ovens, meeting the needs of frequent movement in daily use; in industrial fields, it is suitable for power supply connections of handheld electric tools (such as electric hammers, jigsaws) and small mobile equipment (such as electric forklifts, small welding machines), ensuring that the cable can flexibly follow the movement during equipment operation without damage; in office scenarios, it can be used as connecting cables for projectors, audio equipment, large copiers, etc., facilitating the movement and position adjustment of equipment. In addition, the cable can also be used for wiring in temporary power consumption occasions such as exhibition equipment and stage lighting equipment. Due to its good flexibility, it is convenient for storage and reuse.​ The production process strictly follows IEC 60227 standard, including copper wire drawing, multi-strand precision stranding, PVC insulation layer extrusion, sheath wrapping, cooling and solidification and other processes. Each batch of products must pass multiple tests such as conductor resistance, insulation thickness, flexibility test (repeated bending test) to ensure reliable quality. No special tools are needed for installation, and it can be directly connected to the corresponding plug or terminal. However, it should be noted to avoid excessive stretching and extrusion, and keep away from high temperature and sharp objects. With excellent flexibility and wide applicability, H05V-K cable provides a safe and reliable connection solution for various mobile electrical equipment.
