Copper Plastic Wire BV, ZR-BV BV Wiring cable (lighting wire) general-purpose single-core solid conductor unarmored cable 1. The product is in accordance with national standards GB5023, JB8734. 2. The wire is immersed in water for 1 hour and withstands an AC voltage test of 250V (450/750V), 2000V (300/500V) for 5 minutes without breakdown. BV wiring wire usage characteristics 1. This product is suitable for circuits with an AC rated voltage of 450/750V and below, such as power installations, household appliances, instruments and meters, and telecommunication equipment. 2. The long-term working temperature of the wire should not exceed 70°C; for BV-90 type, it should not exceed 90°C. 3. The installation temperature of the wire should not be lower than 0°C; the minimum bending radius: for wire diameters (D) less than 25mm, it should not be less than 4D; for wire diameters (D) of 25mm and above, it should not be less than 6D. I. Purpose of BV wire: General-purpose single-core solid conductor unarmored cable, suitable for cables and wires used in power devices, household appliances, instruments, and telecommunication equipment with AC voltage of 450/750V and below. It has properties such as acid and alkali resistance, oil resistance, moisture resistance, and mildew resistance. II. Wire model and name: 1. Classification and usage are used to distribute current, belonging to the wiring wire category, indicated by the letter "B"; 2. The conductor material is copper, indicated by the letter "T"; in wiring wires, the copper core conductor is omitted; 3. The insulation material is polyvinyl chloride, indicated by the letter "V"; 4. The structure of the wiring wire is simple; in addition to the above three points, some may also have an outer sheath, with sheath material as polyvinyl chloride also indicated by "V"; if the sheath material is rubber, it is indicated by "X". If there is no sheath and nothing follows, it is not indicated. For example, BVV indicates a copper core polyvinyl chloride insulated round wire with a polyvinyl chloride sheath. III. Common BV wire diameters: Common BV wire diameters: 1.5mm², 2.5mm², 4mm², 6mm², 10mm², 16mm², 25mm², 35mm², 50mm², 70mm², 95mm², 120mm², 150mm², 185mm².
