This product is AVVB-0.66 4X16mm² outdoor steel tape armored power cable, adopting Al/PVC/Sta/PVC multi-layer structure, specially designed for underground power transmission.​ The conductor is made of aluminum, which has stable conductivity and light weight, reducing the bearing pressure of underground laying. The inner PVC insulation layer has good insulation, which can block current leakage; the middle steel tape armor layer provides strong mechanical protection, resisting external forces such as underground soil extrusion and stone collision; the outer PVC sheath has excellent weather resistance, which can resist underground humid and corrosive environments.​ The 4-core 16mm² specification is suitable for 0.66kV low-voltage systems, with a current-carrying capacity of about 45-55A, meeting the needs of small and medium-sized underground power distribution. The steel tape armored structure gives it impact resistance and tensile properties, suitable for direct burial or pipe laying.​ This cable is widely used in outdoor underground power transmission, such as residential area distribution branches and municipal road underground cable networks, providing a safe and durable solution for underground power transmission.
