The 2-core PVC insulated copper cable, as a practical and flexible electrical connection cable with specifications ranging from 1.5-6mm² and a rated voltage of 300/500V, is widely used in building electrical, household appliances, industrial control and other fields due to its unique structural design and excellent performance, making it an ideal choice in medium and low-load circuits.​ In terms of specification parameters, this series of cables covers a variety of cross-sectional sizes, accurately matching different power demands. The conductor of the 1.5mm² cable is stranded with multiple 0.15mm fine copper wires, with a DC resistance of ≤12.1Ω/km at room temperature and an allowable continuous current-carrying capacity of 16A, suitable for power supply lines of lighting fixtures and small household appliances. The 2.5mm² cable has a current-carrying capacity of 25A and a DC resistance of ≤7.41Ω/km, which can meet the power demand of equipment such as air conditioners and electric water heaters. The 4mm² cable has a current-carrying capacity of 32A and a DC resistance of ≤4.61Ω/km, suitable for control circuits of small industrial machinery. The 6mm² cable has a current-carrying capacity of 42A and a DC resistance of ≤3.08Ω/km, capable of handling power transmission for higher-power equipment. The rated voltage of 300/500V not only meets the 220V standard voltage requirement in homes and offices but also can withstand grid fluctuations, providing sufficient guarantee for circuit safety.​ The structural design of the cable highlights practicality. The two cores are insulated from each other and arranged in parallel, with a unified PVC sheath wrapped around the outside, which not only ensures electrical isolation between the two cores but also enhances the stability of the overall structure. The PVC insulation layer and sheath have excellent corrosion resistance, which can resist moisture, dust, and slight chemical erosion in the daily environment. The insulation resistance is ≥100MΩ, effectively preventing the risk of electric leakage. At the same time, the thickness of the insulation layer and sheath increases with the specification. The 1.5mm² cable has an insulation thickness of 0.8mm and a sheath thickness of 0.6mm, while the 6mm² cable has an insulation thickness of 1.0mm and a sheath thickness of 0.8mm, ensuring that cables of different specifications can maintain good mechanical strength and insulation performance.​ Flexibility is a significant advantage of this cable. The stranded technology of multiple fine copper wires makes the minimum bending radius of the cable only 4 times the outer diameter, which can easily adapt to wiring needs in narrow spaces such as corner turns and inside equipment. Even after multiple bendings, the conductor can remain intact, avoiding the risk of breakage due to excessive rigidity. For example, in home decoration, it can be hidden in wall trunking or under the floor, reducing the impact on the aesthetics of the decoration. Inside office equipment, it can flexibly deform with the movement of components, extending the service life of the line.​ The application scenarios are diversified. In the field of building electrical, 1.5-2.5mm² cables are often used in lighting circuits and socket connections, while 4-6mm² cables are suitable for home main circuits and small power lines. In household appliances, it can be used as power connecting lines for washing machines, refrigerators, air conditioners and other equipment, and its flexible design facilitates line adjustment when the equipment is moved. In the industrial control field, 4-6mm² cables can connect assembly line sensors, small motors, etc., withstanding slight vibrations and temperature changes in the workshop environment.​ In addition, the cable has passed the GB/T 5023.4 standard certification, with a sheath oxygen index of ≥28 and self-extinguishing properties, which can quickly flame retardant when exposed to open flames. Each roll of cable is available in 100-meter and 200-meter lengths, supporting cutting according to actual needs to reduce material waste. Overall, this 2-core PVC insulated copper cable, with the advantages of "complete specifications + flexible adaptation + safety and reliability", perfectly balances construction convenience and electrical safety, making it the preferred cable for medium and low-load electrical systems.
