The H07z1-K LSZH cable is a flexible cable specially designed for low-voltage electrical systems, available in two common specifications of 1.5mm² and 2.5mm². It adopts a flexible copper conductor with a rated voltage of 450/750V. Its low smoke zero halogen (LSZH) characteristic makes it outstanding in terms of safety and environmental protection, and it is widely used in places with high requirements for fire safety and the environment.​ In terms of conductor design, the cable uses a flexible copper conductor made of multiple strands of fine copper wires twisted together. The cross-sectional areas of 1.5mm² and 2.5mm² correspond to different current-carrying capacity requirements. The current-carrying capacity of the 1.5mm² cable is about 16-25A, which is suitable for light-load scenarios such as small electrical appliances and lighting circuits; the current-carrying capacity of the 2.5mm² cable can reach 24-32A, which can meet the power supply needs of high-power equipment such as air conditioners and water heaters. The flexible structure endows the cable with excellent bending performance, with a minimum bending radius of only 4-6 times the outer diameter of the cable. It can easily adapt to narrow spaces, frequent movement or bending installation environments, such as internal wiring of mechanical equipment and connection of portable electrical appliances. It is not easy to damage the conductor due to bending during installation.​ Both the insulation layer and the sheath layer are made of LSZH materials, which is one of the core advantages of the cable. When burning, it produces extremely low smoke concentration and high light transmittance, which can reduce the difficulty of evacuation caused by smoke blocking the line of sight in a fire; at the same time, it does not release halogen gases (such as chlorine, bromine) and toxic and harmful substances, avoiding secondary damage to the human respiratory tract and equipment, and complying with international environmental protection and safety standards such as EU EN 50575. In addition, this material also has good temperature resistance. The long-term operating temperature range is -30℃ to 90℃, and the short-term overload temperature can reach 130℃, which can maintain stable insulation performance in high and low temperature environments and resist aging and cracking.​ In terms of electrical performance, the rated voltage of 450/750V makes it suitable for low-voltage power distribution systems in industrial, commercial and civil buildings, and can be used as power cables, control cables or lighting cables. The insulation resistance of the cable is extremely high, not less than 100MΩ·km at 20℃, and the dielectric strength exceeds 20kV/mm, which can effectively prevent electric leakage and short-circuit accidents and ensure the stable operation of the circuit. At the same time, the flexible copper conductor has excellent conductivity. At 20℃, the DC resistance of 1.5mm² is not more than 12.1Ω/km, and that of 2.5mm² is not more than 7.41Ω/km, which can reduce the loss during power transmission.​ In terms of application scenarios, this cable has significant advantages in densely populated or enclosed places such as high-rise buildings, hospitals, schools, subways, and ships. In areas with high requirements for environmental cleanliness such as hospital operating rooms and intensive care units, its LSZH characteristic can avoid equipment damage due to corrosion and ensure the safety of medical staff and patients; in enclosed spaces such as subways and tunnels, it can reduce the risk in case of fire and gain time for personnel evacuation and rescue. In addition, it is also suitable for places with strict requirements on environmental protection and safety such as new energy equipment, laboratories, and data centers, meeting the standards of green buildings and sustainable development.​ The structural design of the cable also takes durability into account. The sheath layer has certain wear resistance, oil resistance and chemical corrosion resistance, which can resist mechanical friction, oil erosion and slight chemical contact in daily use, and prolong the service life. Its surface is usually printed with clear model, specification, voltage level and certification marks, which is convenient for installers to quickly identify and select, and conforms to internationally accepted cable marking standards.​ To sum up, the H07z1-K LSZH cable, with the convenient installation of flexible conductors, high safety of LSZH, stable electrical performance and various specification options, has become an ideal choice in low-voltage electrical systems that takes into account safety, environmental protection and practicability, providing reliable guarantee for power transmission in various scenarios.
