✅ High conductivity, more stable power supply! Key features – Outstanding conductivity, using high-purity copper wire cores, processed through precise twisting technology. The copper purity is high, the resistance is low, and the heat generation is low. At 20℃, the DC resistance of the conductor strictly meets national standards, reducing power transmission loss. It can provide rapid and stable power supply, eliminating problems such as electrical appliance overheating and unstable power supply caused by poor conductivity. It meets the needs of various electrical appliances and engineering power transmission.

✅ 4×1.5 square core, precisely matching the requirements! The four-core parallel twisted design ensures compatibility. The standard specification is 4×1.5 square, with a rated voltage of 300/500V, providing sufficient current capacity. It perfectly suits the engineering power branch wiring and the power supply for small devices. It can also be used for wiring of various electrical appliances (such as small machine tools, office equipment, and large-power household appliances), covering both engineering and electrical usage scenarios. Its practicality is extremely strong.
✅ Copper core wire, outstanding durability! The high-purity copper core wire has a tough texture that resists oxidation and breakage. It doesn’t crack even after repeated bending. Its service life far exceeds that of ordinary copper-core wires. It can withstand frequent wiring and transportation during construction projects, and also meet the high-frequency power supply requirements of long-term electrical use. It combines durability with practicality.
✅ Special protective sheath, safer and more reliable! Complementing with high-quality sheath material, it has both insulation and protection functions. The insulation layer is uniform in thickness and has strong toughness, which can effectively isolate current and eliminate the risks of leakage and short circuit. At the same time, it can withstand the friction and compression during construction, prevent the invasion of external dust and moisture, and protect the wire core from damage. It is suitable for various scenarios such as exposed, concealed, conduit installation and electrical wiring in engineering.
✅ Compatible with both engineering and electrical equipment, covering all scenarios! Widely applied in various engineering power wiring (such as office buildings, factory areas, residential community branch lines), and also suitable for the power connection of various electrical appliances (such as industrial small appliances, office equipment, household appliances). It can be used for multiple purposes, eliminating the need for separate purchases, significantly reducing procurement and construction costs.
✅ Soft and easy to install, with superior efficiency! The cable is overall soft and flexible, allowing for easy bending. The minimum bending radius is only 6 times the outer diameter of the cable. It can easily pass through engineering conduits and channels, and can also flexibly adapt to the complex angles of electrical wiring, bypassing corners and passing through narrow spaces. This significantly reduces the difficulty of wiring and connection, and improves the efficiency of construction and installation.
✅ National standard quality, no worries during acceptance! We strictly follow the relevant national standards for cables in production. Each roll of wire undergoes multiple rigorous inspections, covering key items such as conductivity, copper purity, sheath insulation, and wire diameter specifications. It has passed the CCC certification and has a complete test report, which enables it to smoothly pass the project acceptance. At the same time, it complies with electrical wiring safety standards, providing a more reliable usage experience.
✅ Direct supply from the manufacturer, flexible purchasing makes things more convenient! The factory directly supplies the goods, skipping all intermediate distribution links, eliminating the middleman markup. Bulk purchases can enjoy a stepped discount. It is suitable for both engineering bulk purchases and retail electrical wiring or small batch replenishments. There is an ample supply of goods, and orders can be shipped immediately upon placement. It can promptly meet the construction and installation schedule requirements. A professional team is responsible for addressing the purchasing needs, and all procurement pain points can be solved in one step.
