This series of cables includes U1000 R2V, RO2V, N2xy and Nyy models, covering 3-core and 5-core with multiple specifications. The 3-core ranges from 3X2.5mm² to 3X16mm², and the 5-core includes 5g10mm² to 5g35mm². "U1000" indicates a rated voltage of 1000V, suitable for low-voltage power systems.​ The conductors are made of high-purity copper or high-quality aluminum, with stable conductivity and low energy loss. The insulation layer is made of temperature-resistant and anti-aging materials with high insulation resistance, which can effectively prevent electric leakage. The sheath is made of wear-resistant material, which can resist mechanical damage during daily laying. The 3-core structure is suitable for three-phase power transmission, and the 5-core meets the complex power supply needs with neutral lines.​ 3X2.5mm² to 3X16mm² are applicable to small and medium-power scenarios such as homes and offices, such as home appliance power supply and lighting lines; 5g10mm² to 5g35mm² can be used in shops, small workshops, etc., supporting air conditioners, small equipment and other slightly high-power equipment. They are widely used in low-voltage power distribution of civil buildings and commercial places.​

The NYY unipolar cable is a type of power cable suitable for low-voltage distribution systems, with a designed voltage level of 0.6/1 Kv. It is widely used in power transmission scenarios in industrial, commercial, and civil buildings. This cable adopts a unipolar structure, meaning each cable contains only one conductive core, with cross-sectional areas of 120mm², 150mm², and 185mm² respectively, allowing flexible selection based on different current-carrying capacity requirements. In terms of structure, the core of the NYY unipolar cable is a high-purity copper or aluminum conductor, which has excellent electrical conductivity and can effectively reduce energy loss during power transmission. The conductor is wrapped with a polyvinyl chloride (PVC) insulation layer. PVC material has good insulation, corrosion resistance, and mechanical strength, which can effectively protect the conductor from the external environment and ensure the safe operation of the cable. Outside the insulation layer, there is a PVC sheath, which further enhances the cable's protective capability, enabling it to adapt to various complex environments, such as humid and dusty places, and even withstand mechanical collisions and squeeze to a certain extent. In terms of performance, the voltage level of this cable is 0.6/1 Kv, which means its rated power frequency voltage is 0.6 Kv and the maximum working voltage is 1 Kv. It is suitable for power transmission in low-voltage distribution systems and can be used to connect electrical equipment such as transformers, distribution cabinets, and motors. Cables with different cross-sectional areas correspond to different current-carrying capacities. The 120mm², 150mm², and 185mm² cables can carry different magnitudes of current respectively. Users can select the appropriate specification according to the actual electrical load to ensure the safe and efficient operation of the cable. In addition, the cable also has good heat resistance and can work stably within a certain temperature range. Generally, its long-term allowable operating temperature does not exceed 70℃, and the maximum temperature during a short circuit does not exceed 160℃ (with a duration not exceeding 5 seconds). In terms of installation and use, the NYY unipolar cable can be installed in various ways such as open laying, concealed laying, and pipe threading. During installation, excessive bending and stretching should be avoided to prevent damage to the cable's insulation layer and sheath. At the same time, the cable laying environment should be away from dangerous factors such as high temperature, open flame, and chemical corrosion to extend the service life of the cable. When connecting, appropriate joints and terminals should be used to ensure firm connection and reliable insulation, avoiding faults such as leakage and short circuit. In general, the NYY unipolar cable (0.6/1 Kv, PVC insulation and sheath, 120mm², 150mm², 185mm²) has become an ideal power transmission cable in low-voltage distribution systems due to its excellent performance, reliable protection, and flexible application. It can meet the power demand in different scenarios and provide a strong guarantee for the safe and stable operation of the power system.
