The H07z-K Low Smoke Zero Halogen (LSZH) cable is a high-performance cable specifically designed for industrial installation scenarios. With a cross-sectional area of 25mm², stranded copper conductor, and rated voltage of 450/750V, it can meet the power transmission needs of medium to high-power equipment in industrial environments. Fully compliant with IEC 60754-1 and IEC 61034 standards, it excels in safety, environmental protection, and reliability.​ In terms of core structure, the conductor of this cable adopts a multi-strand stranded copper wire design. The 25mm² cross-sectional area is achieved through a precisely calculated combination of the number and diameter of copper wires. The stranding process not only enhances the flexibility of the cable, making it easy to bend and thread through pipes in the complex wiring environment of industrial workshops, but also improves the mechanical strength of the conductor, enabling it to withstand slight stretching and vibration during installation and long-term use. The high-purity copper conductor (purity ≥99.95%) ensures excellent conductivity, allowing efficient current transmission under rated voltage, reducing line losses, and ensuring the stable operation of industrial equipment.​ The insulation layer and sheath are made of LSZH materials, which is the core advantage distinguishing it from traditional PVC cables. LSZH materials do not release toxic hydrogen halide gases or large amounts of smoke when burned, which can significantly reduce the risk of casualties in fires and minimize corrosive damage to equipment. They are particularly suitable for enclosed environments such as industrial plants with limited ventilation and underground facilities. In addition, this material also has good temperature resistance (long-term operating temperature from -40℃ to 90℃), oil resistance, and chemical corrosion resistance, which can resist erosion from common oil stains, dust, and chemical reagents in industrial environments, extending the service life of the cable.​ In terms of electrical performance, the rated voltage of 450/750V makes it suitable for scenarios such as power circuits, motor connections, and distribution cabinet wiring in industrial fields, and can be adapted to various equipment such as small and medium-sized motors, pumps, and production line control systems. Compliance with IEC 60754-1 (test standard for halogen acid gas emission) and IEC 61034 (test standard for cable smoke density) means that the cable has passed strict environmental and safety tests: the halogen acid gas emission is ≤5mg/g, and the smoke density light transmittance is ≥60%, fundamentally solving the problem of "secondary disasters" of traditional halogen-containing cables in fires.​ In practical applications, the 25mm² H07z-K cable has a current-carrying capacity of approximately 85A (when laid in air, 30℃ environment), which can meet the power supply needs of three-phase equipment (380V) with a power of about 18kW. It is widely used in industrial places with strict safety and environmental protection requirements, such as automobile manufacturing workshops, chemical factories, data center computer rooms, and metallurgical production lines. Its UV resistance also allows it to be used in some outdoor industrial areas, and it can resist aging caused by direct sunlight without additional protection.​ In summary, the H07z-K LSZH cable (25mm²) has become an ideal choice for industrial installations that balance safety, efficiency, and environmental protection, thanks to its high-conductivity stranded copper conductor, environmentally friendly LSZH materials, compliant safety performance, and voltage and current-carrying capacity adapted to industrial scenarios. It provides dual guarantees for the stability of industrial production and personnel safety.
