Copper has excellent electrical conductivity, with low resistance and high conduction efficiency, which can effectively reduce energy loss during power transmission and help users save electricity costs in the long run. At the same time, copper has strong oxidation resistance and corrosion resistance, which can extend the service life of the cable, reduce the frequency of later maintenance and replacement, and lower the long-term maintenance costs of residences and projects. The cross-sectional area of the cable covers the range of 1-10mm², and this specification design is highly practical. The 1-10mm² cross-sectional area range can meet the electricity demand of different scenarios: small cross-sectional areas (such as 1-2.5mm²) are suitable for low-load circuits such as lighting circuits and sockets for small household appliances in residences; medium cross-sectional areas (such as 4-6mm²) can be used for power supply lines of high-power household appliances such as air conditioners and water heaters; larger cross-sectional areas (such as 10mm²) can be adapted to high-load scenarios such as power equipment and main lines in engineering. There is no need to frequently replace cables of different specifications, which provides convenience for construction and reduces the complexity of procurement and inventory management. "Flexibility" is another major advantage of this cable. The flexible design makes the cable easier to bend and drag during the wiring process, which is especially suitable for scenarios such as concealed wiring in residential walls, wiring in ceilings, and complex pipeline layout in engineering. Whether it is going around corners, passing through narrow conduits, or adjusting the direction in irregular spaces, the flexible cable can handle it easily, reducing construction difficulty, improving wiring efficiency, and avoiding the risk of bending and breaking caused by the excessive rigidity of the cable, thus ensuring the integrity of the line. The environmental protection attribute runs through the entire product.
