PVC insulated THW cable is a commonly used cable in house wiring. It adopts 7-strand pure copper conductors with specifications covering 8, 10, 12, and 14 AWG, which can meet the needs of different household electrical scenarios and provide stable and safe power transmission guarantee for the household electrical system.​ In terms of conductor structure, each conductor of the cable is composed of 7 strands of pure copper wire stranded together. The pure copper material (purity ≥99.9%) has excellent conductivity, which can efficiently transmit current and reduce line loss. The 7-strand stranded design not only enhances the flexibility of the conductor, making it easy to bend and thread through pipes in house wiring, adapting to complex laying environments such as walls and floors, but also improves the mechanical strength of the conductor, which can withstand slight stretching and vibration during installation and long-term use, extending the service life of the cable. Different AWG specifications correspond to different conductor diameters and current-carrying capacities: 14 AWG has a conductor diameter of about 1.63mm and a current-carrying capacity of about 15A, suitable for low-power equipment circuits such as lighting fixtures and small household appliances; 12 AWG has a conductor diameter of about 2.05mm and a current-carrying capacity of about 20A, which can be used for socket circuits and medium-power appliances such as hair dryers and microwave ovens; 10 AWG has a conductor diameter of about 2.59mm and a current-carrying capacity of about 30A, suitable for power supply circuits of high-power appliances such as air conditioners and electric water heaters; 8 AWG has a conductor diameter of about 3.26mm and a current-carrying capacity of about 40A, mostly used for main incoming lines of families or dedicated line power supply for large appliances.​ The insulation layer is made of polyvinyl chloride (PVC) material, which complies with the THW standard (moisture-resistant tropical type). It has good water resistance, oil resistance, and chemical corrosion resistance, and can adapt to humid environments such as kitchens and bathrooms in families. The thickness of the insulation layer varies according to specifications: 8 AWG is about 0.8mm, 10 AWG is about 0.7mm, 12 AWG is about 0.6mm, and 14 AWG is about 0.5mm, all of which can provide reliable insulation protection to prevent electric leakage accidents. At the same time, the PVC insulation layer has certain flame retardant performance, which can delay combustion in high temperature or early fire, buying time for personnel evacuation and fire fighting.​ In house wiring applications, the diversified specifications of the cable can achieve precise matching: 14 AWG and 12 AWG are widely used in indoor lighting and ordinary socket circuits to meet the needs of daily electrical equipment; 10 AWG and 8 AWG are separately wired for high-power appliances to avoid problems such as tripping or line overheating caused by overload. Its color identification is clear, commonly including black, white, red, etc., which is convenient for distinguishing different circuits and simplifying the installation and later maintenance processes.​ In addition, the rated voltage of the cable is 600V, which meets the household electricity voltage standard, and can work stably for a long time in the ambient temperature range of -15℃ to 60℃, adapting to the climate conditions in different regions. Overall, relying on high-quality pure copper conductors, reliable PVC insulation layers, diverse specification options, and good adaptability, PVC insulated THW cable has become an ideal choice for house wiring, providing a solid guarantee for household electricity safety.

PVC insulated earthing/grounding copper cables are specialized wires designed for grounding and earthing systems in electrical setups. Their core function is to reliably connect metal enclosures of electrical equipment, line structures, etc., to the ground, forming a safe loop to discharge fault currents, prevent electric shock accidents, and stabilize system voltage. This series of cables offers five cross-sectional area specifications: 70mm², 50mm², 35mm², 25mm², and 16mm², all using stranded copper conductors, suitable for electrical systems of different power levels.​ In terms of conductor characteristics, the stranded copper material is a significant advantage. Copper, as a high-conductivity metal, can quickly conduct fault currents, ensuring the timeliness of grounding response. The stranded structure enhances the cable's flexibility, making it easy to bend, lay, and fix in complex wiring environments (such as building wall interlayers and narrow spaces at the bottom of equipment), reducing construction difficulty. The different cross-sectional area designs correspond to diverse application scenarios: 16mm² and 25mm² are suitable for low-power grounding systems such as small industrial equipment and household distribution boxes; 35mm² and 50mm² can meet the grounding needs of medium-sized production lines and commercial buildings; 70mm² is applicable to high-power scenarios like large substations and high-voltage transmission lines, ensuring stable performance even under high current impact.​ The insulation layer is made of polyvinyl chloride (PVC) material, which has multiple practical properties. The PVC insulation layer not only has high insulation resistance, effectively isolating the conductor from the external environment and preventing leakage risks, but also has good corrosion resistance, which can resist acid-base substances in the soil, moisture in the air, and slight chemical erosion, extending the service life of the cable. In addition, PVC material has moderate cost and mature processing technology, making the cable have high cost performance while ensuring performance, suitable for large-scale promotion and application.​ In terms of safety performance, this series of cables strictly complies with international standards for grounding systems (such as IEC, GB, etc.) and has passed multiple tests including insulation strength, aging resistance, and flame retardancy. The low impedance characteristic of its grounding loop can quickly conduct fault currents into the ground, avoiding electrification of equipment enclosures; at the same time, the self-extinguishing property of the PVC insulation layer can delay combustion in case of open fire, reducing the risk of fire spread.​ In terms of installation, the outer PVC sheath of the cable is smooth and wear-resistant, facilitating installation through pipes, burial, or open laying, and is suitable for various environments such as soil, concrete, and air. Cables of different specifications can be flexibly combined through terminals, connectors, and other accessories to meet the topological requirements of different grounding networks. Whether it is an independent grounding, shared grounding, or combined grounding system, it can provide reliable connection support.​ In summary, with multi-specification adaptability, high-conductivity stranded copper conductors, durable PVC insulation layers, and excellent safety performance, PVC insulated earthing/grounding copper cables have become an ideal choice for grounding systems in industrial, construction, power, and other fields, providing solid protection for the safe operation of electrical equipment and personnel protection.
