The 3 core flexible cable is an excellent and widely used cable product, with specifications mainly including 1.5mm² and 2.5mm². It adopts multi-strand stranded copper conductors, XLPE (cross-linked polyethylene) insulation layer and PVC (polyvinyl chloride) sheath. With its excellent characteristics, it plays an important role in many fields.​ In terms of conductors, the cable uses multi-strand stranded copper conductors. As a high-quality conductive material, copper has extremely high conductivity, which can transmit electricity efficiently, reduce energy loss, and ensure the stability of power transmission. The multi-strand stranded structure endows the cable with excellent flexibility, enabling it to easily cope with various bending and twisting scenarios. Even in cases where the wiring space is narrow and the path is complex, it can be installed conveniently, greatly reducing the construction difficulty. At the same time, this structure also enhances the fatigue resistance of the cable, making it not easy to break in environments with frequent movement or vibration, thus prolonging the service life of the cable.​ The insulation layer is made of XLPE material, which has many excellent properties. XLPE material has high insulation resistance, which can effectively insulate current, prevent electric leakage accidents, and ensure the safety of power transmission. It has excellent temperature resistance and can maintain stable insulation effect in higher temperature environments (usually 90℃ and above), not easy to age or crack. Compared with traditional PVC insulation materials, it has a longer service life and can adapt to more harsh working environments. In addition, XLPE material also has good chemical corrosion resistance and mechanical strength, which can resist the erosion of various chemical substances and the impact of external mechanical forces, protecting the conductor from damage.​ The sheath of the cable is made of PVC material, which has good wear resistance, weather resistance and moisture resistance. It can effectively protect the internal insulation layer and conductor of the cable, resist the erosion of dust, water vapor, oil stains and other substances in the external environment, and prolong the service life of the cable. At the same time, PVC material has good processing performance, making the sheath surface smooth and flat, easy to clean, and has certain flexibility, which does not affect the overall flexibility of the cable.​ In terms of applicable scenarios, the 1.5mm² 3 core flexible cable is suitable for equipment and scenarios with relatively small power. For example, the power supply of small household appliances, such as washing machines, microwave ovens, vacuum cleaners, etc.; the connection lines of office equipment such as printers and copiers in office places; and the control lines of small industrial equipment, etc. The 2.5mm² cable is suitable for equipment with slightly higher power, such as the power supply lines of air conditioners, electric water heaters, small motors, etc., and can also be used for branch distribution lines in buildings to meet the transmission needs of larger currents.​ In addition, due to its good flexibility and durability, the cable is also often used for power supply of mobile equipment, such as electric tools, stage lighting equipment, temporarily built activity power supply lines, etc. It can also be seen on construction sites, used for temporary power connections to provide stable power support for construction equipment.​ Whether in home, office, industrial or temporary power supply scenarios, the 3 core flexible cable can provide safe and stable guarantee for power transmission with its excellent conductivity, good flexibility, reliable insulation and sheath protection. It is a practical and widely used cable product.
