What belongs to the plurality of soft copper wire
The letter B stands for wiring (for example: the indoor power line, the nail on the wall cloth), voltage: 300/500V. V - PVC sheath letters (a V represents an insulating layer of two V, which is representative of double insulation) plastic insulating layer. L stands for aluminum, and copper is represented without L. The letter "R" represents the meaning of the flexible cord. To be soft, it is to increase the number of conductors and reduce the diameter of each wire. The structure: the conductor is copper wire, and the diameter of each copper wire is less than one millimeter.
How is not by hot rolled copper soft copper wire annealing (but smaller size wire may require intermediate annealing) drawn from the wire, can be used for weaving, cable, copper brush filter etc..
BV is a single core copper wire, hard, inconvenient construction, but the intensity is large; BVR is a multi-core copper wire, soft and convenient construction, but the intensity is small. BV single core copper wire is generally used for more fixed place; BVR multi-core copper wire is generally used for slight movement occasions. In addition, the carrying capacity of BVR multiple strands is larger than that of single strands, and the price is higher. Usually inside the cabinet can use BVR, not so much strength, convenient wiring.
Copper conductor PVC insulated flexible sheath wire.Commonly used PVC insulated wires are: BV, BLV, BVR.
