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.​
