BV electrical cable, a commonly used wire in the field of house wiring, is favored for its stable performance and wide applicability. Especially the solid copper wire PVC insulation products with specifications of 1.5mm², 2.5mm², 4mm², 6mm², and 10mm², which meet the diversified needs of household electricity use.​ In terms of specifications, this series of BV cables covers different electrical load scenarios. The 1.5mm² cable is often used in lighting circuits, and its current-carrying capacity is sufficient to support the stable operation of low-power equipment such as lamps; the 2.5mm² is widely used in ordinary socket circuits, which can meet the electricity needs of common household appliances such as TVs, refrigerators, and washing machines; the 4mm² is suitable for separate circuits of high-power appliances such as air conditioners and electric water heaters, which can withstand higher currents; the 6mm² and 10mm² are mostly used for incoming lines or main lines from the household main switch to each branch, providing strong power transmission guarantee for the entire household electrical system. This multi-specification design allows construction personnel to accurately select according to different electrical loads, avoiding resource waste or overload risks.​ In terms of materials, the conductor of BV cable is made of high-purity solid copper wire. Copper has excellent electrical conductivity, with high conductivity and low resistance, which can effectively reduce energy loss during current transmission and ensure the efficient operation of electrical equipment. At the same time, copper wire has high mechanical strength and is not easy to break, ensuring the stability of the cable during installation and use. The insulation layer is made of polyvinyl chloride (PVC) material. PVC has good insulation performance, which can effectively insulate current and prevent electric leakage accidents. In addition, PVC also has properties such as acid and alkali resistance, oil resistance, and aging resistance, which can adapt to the complex environment in the house and extend the service life of the cable.​ In terms of performance, BV cable performs well. Its insulation layer has good temperature resistance and can withstand temperature changes within a certain range. Even in the peak of electricity use in summer or when electrical appliances run for a long time and generate high temperatures, it can maintain a stable insulation effect. At the same time, the cable has good tensile and bending resistance. During wiring, whether it is thread，buried in the wall or exposed laying, it can adapt to different installation methods and is not easy to be damaged by external forces. Moreover, after strict production process treatment, the conductor and insulation layer of BV cable are closely combined, and it is not easy to delaminate, further ensuring electrical safety.​ In terms of application scenarios, BV cable is specially designed for house wiring, covering various electrical areas in the home. In the living room, it can supply power to chandeliers, TVs, stereos and other equipment; in the bedroom, it meets the electricity needs of air conditioners, desk lamps, chargers, etc.; in the kitchen, it provides stable power for high-power appliances such as refrigerators, microwave ovens, and electric ovens; in the bathroom, it is suitable for equipment such as electric water heaters and bathroom heaters. Its diversified specifications and reliable performance ensure the safe and stable operation of the household electrical system, providing a solid power guarantee for residents' daily life.​ To sum up, BV electrical cable (1.5/2.5/4/6/10mm² solid copper wire PVC insulation) has become an ideal choice for house wiring due to its reasonable specification division, high-quality materials, and excellent performance, playing an important role in ensuring household electrical safety and improving electricity efficiency.
