This product is the Royal Cord series of flexible power cables, covering four core specifications: 12/2, 12/3, 14/2, and 14/3. Designed in the SJTW style, it has a rated voltage of 600V, with stranded conductors and an outer PVC jacket. Relying on excellent flexibility, environmental resistance, and electrical safety, it is widely used in various scenarios requiring flexible wiring, including power supply for household appliances, connection of small power tools, power extension for commercial equipment, and indoor and outdoor temporary or fixed power transmission needs (subject to the environmental adaptation range of the SJTW style).​ In terms of core specifications and structural design, the specification labels (12/2, 12/3, 14/2, 14/3) of this series of power cables contain key parameters: the first number (12 or 14) represents the conductor gauge (AWG). The 12 AWG conductor has a larger cross-sectional area and stronger current-carrying capacity, suitable for medium and high-power equipment (such as small air conditioners, high-power power tools); the 14 AWG is more suitable for low-power scenarios (such as table lamps, small household appliances). The latter number (2 or 3) indicates the number of conductors. The 2-conductor cable includes a live wire and a neutral wire, meeting basic power supply needs; the 3-conductor cable additionally has a ground wire, suitable for equipment with strict safety grounding requirements (such as household appliances with metal casings, power tools), which can effectively prevent electric leakage risks and improve electrical safety. All specifications adopt a stranded copper conductor design. Compared with single-core conductors, the multi-strand twisted structure greatly improves the flexibility of the cable, allowing it to be easily bent and folded to adapt to complex wiring environments. At the same time, it reduces the risk of conductor breakage caused by bending and extends the service life.​ The SJTW style is one of the core characteristics of this power cable, which defines the sheath performance and applicable environment of the cable. "S" stands for service cable, "J" indicates rigid PVC insulation, "T" refers to thermoplastic sheath, and "W" means it has a certain degree of weather resistance, which can be used in humid environments or short-term outdoor rain conditions (but it should be noted that it is not designed for long-term outdoor exposure or direct burial). The outer PVC jacket not only endows the cable with excellent flexibility, facilitating storage and wiring operations, but also has excellent wear resistance and chemical corrosion resistance. It can resist friction and collision in daily use, as well as contact with common chemicals (such as cleaning agents, lubricating oils), protecting the internal conductors and insulation layer from damage. At the same time, the PVC jacket has good electrical insulation. Combined with the insulation layer of the internal conductor, this double protection can effectively isolate the current, prevent electric leakage accidents, and ensure stable operation under the rated voltage of 600V.​ In terms of application scenarios, the diverse specifications and flexible characteristics of this series of power cables make it widely applicable. The 12/2 and 12/3 specifications have strong current-carrying capacity and can be used to connect high-power air conditioners in living rooms, kitchen refrigerators, commercial small equipment (such as coffee machines, printers), and power tools (such as electric drills, grinders). The 3-conductor version is especially suitable for high-risk equipment such as power tools, reducing the risk of electric shock through the grounding function; the 14/2 and 14/3 specifications are more suitable for low-power household appliances such as bedroom table lamps, bedside chargers, and small fans, as well as power extension for office equipment such as office computers and projectors. Its weather-resistant design also allows it to be used in semi-outdoor or humid environments such as balcony lighting and garage power tool power supply, but it should avoid long-term exposure to extreme high temperatures, severe cold, or highly corrosive environments. In addition, the flexible characteristics make this cable outstanding in temporary wiring scenarios (such as exhibition equipment power supply, temporary electricity use in home decoration). It can flexibly adjust the wiring path according to needs, and is easy to store after use without permanent bending damage.​ In terms of quality and compliance, the Royal Cord series power cables strictly follow relevant electrical cable production standards. From the selection of conductor materials (high-purity copper), the PVC material formula of the insulation layer and sheath, to the production processes such as stranded conductor twisting and sheath extrusion, all undergo strict quality control. The product has passed electrical performance tests (such as insulation resistance, voltage resistance test), mechanical performance tests (such as bending test, tensile test), and weather resistance tests to ensure that the current-carrying, insulation protection, flexibility and durability of cables of various specifications meet safety standards. The surface of the cable is clearly printed with specification labels, rated voltage, SJTW style, production batch number, and safety warnings, which is convenient for users to identify and inspect, and provides a basis for later maintenance and traceability, comprehensively ensuring the user's electrical safety and stable operation of equipment.
