The underground SWA cable involved in this abstract is a special cable suitable for medium and low voltage distribution systems. Its specification parameters and structural design make it widely applicable in industrial, civil, and infrastructure construction. The rated voltage of this cable is 0.6/1kV, which belongs to the category of low-voltage cables. It is mainly used in distribution networks with a rated voltage of 1kV and below, and can meet the power transmission needs of scenarios such as internal building distribution, underground laying lines, and outdoor engineering. In terms of conductor material, the cable uses high-purity copper core as the conductor. Copper has excellent electrical conductivity and thermal conductivity, with a low resistivity, which can effectively reduce energy loss during current transmission and ensure the efficiency and stability of power transmission. At the same time, copper has high mechanical strength and is not easy to break, which can adapt to complex stress conditions in the underground laying environment. The core design of the cable is 4 cores of 120mm² plus 1 core of 185mm², and this structure takes into account the diversity and safety of power transmission. Among them, the 4 cores of 120mm² are usually used to transmit the phase lines and neutral lines of three-phase alternating current to meet the power supply needs of three-phase loads; while the 1 core of 185mm² has a larger cross-section, which is generally used as a grounding wire (PE line). Its larger cross-sectional area can reduce the grounding resistance, improve the reliability of the grounding system, and in the event of leakage or short-circuit faults, it can quickly conduct the fault current into the ground to ensure the safety of personnel and equipment. The insulation layer and sheath are made of XLPE (cross-linked polyethylene) and PVC (polyvinyl chloride) materials. As an insulation layer material, XLPE has excellent electrical insulation performance, temperature resistance, and chemical corrosion resistance. Its operating temperature range is wide, and it can operate stably in an environment of -40℃ to 90℃, which can effectively resist the erosion of the insulation layer by moisture, acid, alkali substances, etc. in the underground soil. As a sheath material, PVC has good mechanical strength, wear resistance, and flame retardancy, which can provide solid physical protection for the internal structure of the cable, prevent mechanical damage during laying, and delay the aging effect of the external environment on the cable. In addition, the cable has an SWA (steel wire armoring) structure, that is, one or more layers of steel tape armoring are added inside the sheath. The main function of steel armoring is to enhance the mechanical protection ability of the cable, enabling it to withstand large tension, pressure, and impact force. It is suitable for underground installation methods such as direct buried laying and pipe laying, effectively resisting damage from external factors such as soil pressure and stone extrusion. Overall, this underground SWA cable, with its reasonable structural design, high-quality material selection, and reliable performance parameters, can meet the needs of safe, efficient, and long-term operation in underground distribution environments. It is an ideal choice for low-voltage distribution systems in industrial plants, residential communities, municipal engineering, and other fields.

The RVV power cable is a low-voltage power supply cable specially designed for home appliances. With the excellent performance of stranded copper wires, flexible core count options, and adaptable wire gauge specifications, it has become a core accessory to ensure the safe and stable operation of home appliances. Its core advantages are concentrated in three dimensions: electrical conductivity, structural adaptability, and safety protection, which can be widely matched to the power supply needs of various household scenarios. In terms of conductor material and electrical conductivity, this cable uses stranded copper wires as the conductive core. Compared with single-strand hard wires or copper alloy wires, the stranded structure not only has better flexibility (facilitating bending and threading through pipes when wiring inside narrow spaces of home appliances or in household wiring) but also improves current transmission efficiency through tight stranding between strands. The purity of the conductor is strictly controlled to ensure low resistance characteristics. Even when home appliances operate at high load for a long time (such as air conditioners cooling or electric ovens heating), it can effectively reduce losses during current transmission and avoid potential safety hazards caused by excessive heating of the conductor. The wire gauge specifications cover 0.5-6mm², which can accurately adapt to home appliances of different powers: thin-gauge cables of 0.5-1mm² are suitable for small home appliances (such as table lamps, electric shavers, and small humidifiers) to meet low-power supply needs; medium-gauge cables of 1.5-2.5mm² are suitable for medium-power home appliances (such as washing machines, refrigerators, and microwave ovens); thick-gauge cables of 4-6mm² can support high-power home appliances (such as electric water heaters, cabinet air conditioners, and electric ovens) to ensure stable power supply without tripping. In terms of core count design, three options (2-core, 3-core, and 4-core) are provided to adapt to the circuit needs of different home appliances: 2-core cables are mostly used for simple home appliances that do not require grounding (such as table lamps and chargers), only transmitting live wires and neutral wires; 3-core cables add a ground wire, which is a standard configuration for home appliances with metal casings (such as refrigerators, washing machines, and air conditioners). It can conduct current to the ground in case of equipment leakage to ensure user safety against electric shock; 4-core cables are suitable for some home appliances with complex functions (such as high-end washing machines with intelligent control modules and built-in ovens). In addition to live wires, neutral wires, and ground wires, the extra core can be used for signal transmission or auxiliary power supply to meet the multi-functional operation needs of home appliances. The insulation and sheath layers of the cable are made of polyvinyl chloride (PVC) material that meets national standards, with good insulation, temperature resistance, and wear resistance. The insulation layer tightly wraps each copper wire to effectively isolate the conductor from external contact and prevent short circuits; the outer sheath further enhances the cable's anti-aging ability and mechanical protection performance, which can resist slight friction and extrusion in daily use, and avoid insulation failure caused by changes in environmental humidity or slight chemical corrosion (such as kitchen oil pollution and bathroom moisture). In addition, the sheath material also has a certain flame-retardant property, which can slow down the spread of flames in extreme cases and add an extra layer of protection for home safety. In terms of application scenarios, this RVV power cable covers almost all household fields: in the kitchen, it can provide stable power supply for microwave ovens, rice cookers, and dishwashers; in the living room, it is suitable for equipment such as air conditioners, TVs, and stereos; in bedrooms and bathrooms, it meets the electricity needs of home appliances such as humidifiers, electric heaters, and electric water heaters.

The building wire with 2.5mm², 4mm², 6mm² solid copper core and XLPE insulation (300/500V) is a core power transmission product specially designed for house wiring. With a rated voltage of 300/500V, it uses solid copper as the conductor and cross-linked polyethylene (XLPE) as the insulation layer, covering three commonly used cross-sectional specifications. Relying on its excellent electrical performance, safety stability, and durability, it has become an ideal choice for modern household high-voltage wiring. It is widely used in lighting circuits, socket circuits, and dedicated lines for high-power appliances (such as air conditioners, water heaters, and refrigerators) in living rooms, bedrooms, kitchens, bathrooms, and other areas of family homes, providing a safe and efficient power supply guarantee for the household power system.​ In terms of core specifications and voltage adaptability, the rated voltage of 300/500V accurately matches the standards of China's household low-voltage distribution system (single-phase 220V, three-phase 380V). Among them, 300V is the phase voltage tolerance value, and 500V is the line voltage tolerance value. It can stably withstand voltage fluctuations during household electricity use, avoid insulation breakdown caused by voltage overload, and ensure circuit safety. The three cross-sectional specifications correspond to different household electricity load requirements: the 2.5mm² specification has a current-carrying capacity of approximately 16-25A, suitable for lighting circuits and ordinary socket circuits (such as low-power equipment like mobile phone charging, desk lamps, and TVs), and is the most widely used basic wiring specification in families; the 4mm² specification has a current-carrying capacity of approximately 25-32A, suitable for high-power socket circuits or dedicated lines for small appliances (such as wall-mounted air conditioners, electric ovens, and washing machines), meeting the electricity needs of medium-power equipment; the 6mm² specification has a current-carrying capacity of approximately 32-40A, specially designed for dedicated lines for high-power appliances (such as cabinet air conditioners, electric water heaters, and integrated stoves), which can cope with high-load electricity scenarios, avoid safety hazards caused by conductor overload and heating, and realize scientific wiring of "selecting specifications according to needs".​ The selection of solid copper conductor is one of the core advantages of this wire. Compared with stranded copper conductors or aluminum conductors, solid copper conductors have better electrical conductivity, which can effectively reduce energy consumption and heat generation during current transmission, reduce line losses, ensure efficient transmission of electrical energy to terminal equipment, and at the same time reduce the risk of fire caused by conductor overheating. It has higher mechanical strength, is not easy to break due to bending and pulling, and is suitable for complex construction scenarios such as wall penetration, pipe penetration, and concealed installation in house wiring. Moreover, it is not easy to have conductor oxidation and rust problems during long-term use, can maintain stable electrical performance, and extend the service life of the wire. In addition, the solid copper conductor has good fatigue resistance, and can maintain structural stability even when the household electricity load changes frequently, avoiding circuit failures caused by conductor fatigue.​ The XLPE insulation layer provides reliable electrical isolation and safety protection for the wire. After special cross-linking treatment, the cross-linked polyethylene material forms a three-dimensional network molecular structure. Compared with the traditional PVC insulation layer, it has better high-temperature resistance (long-term operating temperature up to 90℃, short-term overload temperature up to 130℃). Even in the local high-temperature environment generated by long-term operation of high-power appliances, it is not easy to have problems such as softening, deformation, and aging of the insulation layer, which greatly reduces the risk of short circuits. It has stronger insulation performance and high dielectric strength, which can effectively isolate the conductor from the external environment and prevent leakage accidents. It is especially suitable for humid (such as bathrooms, kitchens) and dusty environments in families, avoiding insulation failure caused by environmental factors. At the same time, the XLPE material also has good chemical corrosion resistance and aging resistance, which can resist the erosion of common cleaning agents and water vapor in families. It is not easy to degrade even when buried in walls or used in pipes for a long time, extending the service life of the wire and reducing the cost of later maintenance and replacement.​ From the perspective of the practicality of house wiring, the design of this wire fully considers the needs of home decoration scenarios. The rigidity of the solid copper conductor is moderate, which is easy to operate during pipe wiring, can accurately pass through narrow wire pipes, and reduces construction difficulty; the flexibility of the XLPE insulation layer is good, which can be flexibly bent according to the wiring path, adapting to the complex wall structure and furniture layout of the family. Moreover, the surface of the insulation layer is smooth, and the friction force is small during pipe penetration, which is convenient for construction personnel to push forward quickly. In addition, the outer skin of the wire usually adopts color identification (such as red, yellow, green, blue, yellow-green two-color, etc.), among which the yellow-green two-color is the special color for the ground wire. Different colors correspond to different circuit functions, which is convenient for construction personnel to distinguish the live wire, neutral wire, ground wire, and different circuits, reduces the probability of wiring errors, and also facilitates later circuit maintenance and repair, improving the safety and convenience of house wiring.​ In terms of safety performance, the XLPE insulation layer also has good flame-retardant characteristics, complying with national building wire flame-retardant standards (such as GB/T 19666). In the event of a fire, it can effectively slow down the spread speed of the flame and reduce the release of toxic smoke, gaining valuable time for family members to evacuate and reducing the harm of fire to personnel. At the same time, its low-smoke and halogen-free characteristics (for some models) can reduce the generation of harmful gases in the fire, further improving the safety level of household electricity use, especially suitable for families with the elderly and children.​ In conclusion, the building wire with 2.5mm², 4mm², 6mm² solid copper core and XLPE insulation (300/500V) for house wiring perfectly meets the core needs of "safety, stability, and durability" for house wiring through precise specification design, high-quality material selection, and comprehensive safety performance optimization. It can not only ensure the reliability and safety of daily household electricity use but also adapt to the needs of future household electricity load growth (such as adding high-power appliances), creating a safe and efficient power infrastructure for modern families, and having extremely high practical value and market recognition.
