BV 1 core solid cable is an ideal choice for home and building wiring, with a rated voltage of 450/750V and cross-sectional areas ranging from 1mm² to 16mm². It uses high-purity solid copper wire as the conductor and is covered with a high-quality PVC insulation layer, combining safety and durability. The conductor is made of electrolytic copper with a purity of over 99.95%. After annealing treatment, its conductivity is ≥58MS/m, ensuring efficient current transmission. Different cross-sectional areas are suitable for different electrical scenarios: 1mm² is applicable to small lighting fixtures; 1.5mm² can meet the needs of ordinary lighting circuits; 2.5mm² is often used for power supply of ordinary sockets; 4mm² to 10mm² can carry high-power appliances such as air conditioners and electric water heaters; 16mm² is suitable for home main lines or small power distribution systems. The current-carrying capacity increases from 12A to 80A with the increase of cross-sectional area (at an ambient temperature of 30℃). The thickness of the PVC insulation layer increases from 0.6mm to 1.4mm with the specification. The insulation resistance is ≥100MΩ, which can withstand a 2kV power frequency withstand voltage test, effectively isolating current. The insulation layer complies with UL94 V-0 flame retardant standards, self-extinguishing within 30 seconds after the open flame is removed, and has an operating temperature range of -15℃ to 70℃, adapting to various environments in home buildings. The surface of the cable is printed with clear marks, including specifications, voltage level, certification marks (such as GB 5023, IEC 60227) and production information, facilitating construction identification and quality traceability. Various colors (red, blue, yellow, etc.) can distinguish phase lines and neutral lines, reducing the risk of wiring errors. Its single-core solid structure has strong rigidity, suitable for fixed wiring scenarios such as wall embedding and pipe laying, providing stable and reliable power support for home building electrical systems.
