The 1.5mm²-2.5mm² ultra flexible Low Smoke Zero Halogen (LSZH) wire H07z1-K, as a high-performance cable with authoritative certification, demonstrates irreplaceable advantages in scenarios with strict requirements for safety and flexibility, such as precision electronic equipment, rail transit, and high-rise buildings, thanks to its unique ultra flexibility, halogen-free characteristics, and reliable performance.​ In terms of specifications, the 1.5mm² and 2.5mm² conductor cross-sections accurately match low to medium power consumption needs. The 1.5mm² wire has a conductor diameter of approximately 1.38mm, with a DC resistance of no more than 12.1Ω/km at room temperature and a current-carrying capacity of up to 16A, suitable for internal wiring of small motors, sensors, and precision instruments. The 2.5mm² wire has a conductor diameter of about 1.78mm, a DC resistance of no more than 7.41Ω/km, and a current-carrying capacity of 25A, meeting the needs of medium-load scenarios such as office equipment clusters and medical instrument power supply. Both wires comply with the H07z1-K standard certification, with a rated voltage of 450/750V, far exceeding the power demand of conventional low-voltage equipment, providing sufficient safety margin for voltage fluctuations.​ Material and performance are its core competitiveness. The conductor is made of stranded multi-strand fine copper wires, with far more strands than ordinary wires. Combined with a special annealing process, it endows the wire with excellent flexibility—it can withstand tens of thousands of bends without breaking the core, with a minimum bending radius of only 4 times the cable outer diameter. It is particularly suitable for complex wiring in narrow spaces, such as internal lines of robots and automotive wire harnesses that require frequent movement. The insulation layer is made of LSZH material, free of halogen elements such as chlorine and bromine. When burned, it releases extremely low smoke density (light transmittance ＞80%), and the released gas has a near-neutral pH value, which will not corrode equipment or harm the human body. It has passed the IEC 60332-1-2 flame retardancy test, effectively delaying flame spread.​ In terms of characteristic applications, this wire is widely used in fields with dual strict requirements for safety and flexibility. In medical equipment, such as internal wiring of ventilators and monitors, its ultra flexibility can avoid line wear during equipment movement, and the halogen-free characteristic meets the requirements of clean environments such as operating rooms. In the rail transit field, lighting and communication lines in subway carriages use this wire, which can not only adapt to frequent bending caused by vehicle vibration but also reduce smoke obstruction during fire accidents. In smart home systems of high-end residences, 1.5mm² wires can be hidden in furniture and wall gaps, while 2.5mm² wires are used for power supply of smart curtains and security equipment, balancing aesthetics and safety.​ In addition, the H07z1-K certification ensures that it meets the access standards of international markets such as the European Union, making it suitable for supporting export-oriented equipment. Its surface is printed with clear specifications, certification marks, and meter markers, facilitating quick identification and cutting during construction and improving installation efficiency. In summary, this wire, through the combination of "ultra flexibility + halogen-free + high certification", perfectly balances functionality and safety, becoming the preferred solution for wiring in precision scenarios.
