Black BV line
BV wire, referred to as plastic copper wire, full name is copper core PVC insulated cloth wire. B represents the category of cloth wires, and V represents the insulation is polyvinyl chloride. Suitable for cables and wires used for AC voltage 450/750V and below power plants, household appliances, meters and telecommunications equipment
Type: BV lines are divided into: ZR-BV and NH-BV.
ZR-BV: Copper core PVC insulated flame-retardant wire: the insulation material is added with flame retardant, and it will not ignite spontaneously away from open flame. Flame-retardant BV lines are divided into three grades: A, B, and C, of which A is the best, and so on, the most commonly used is ZR-BV.
NH-BV: Copper core PVC insulated fire-resistant wire: it can be used normally under normal fire conditions.
BV flexible wire is indicated by BVR, BV rubber copper wire is indicated by BX, BV rubber and aluminum is indicated by BLX, BV plastic and aluminum is indicated by BLV, fire-resistant BV wire is indicated by NH-BV, and flame-retardant BV wire is indicated by ZR-BV
General purpose single-core hard conductor non-sheathed wire, suitable for cables and wires for AC voltage 450/750V and below power plants, household appliances, meters and telecommunication equipment.
Ordinary insulated wires, household wires, are the most commonly used wire types. Take a 100-square-meter new house as an example, 4 square meters of copper core BV wire 200 meters, 2.5 meters of 400 meters, 1.5 square meters of 300 meters, and 1.5 square meters of copper core BV two-color wire 100 meters. The above mentioned is no ceiling decoration, if you want to ceiling, the 1.5 line needs a little more BV line diameter square number: 0.2 0.3 0.4 0.5 300 400 square.
