For many consumers who decorate home wire, are not clear about the difference between bv wire and rv wire, these two specifications of wire, whether from the naming method, or structure and scope of use are there is a gap, take you to understand the bv wire and rv wire: BV: Copper core PVC insulated wire is a single core wire of copper wire, because it is relatively hard, so it is also called hard wire. RV: Copper core polyvinyl chloride insulated connection soft wire, is a flexible wire, is more strands of copper wire twisted together single-core wire. Difference between bv wire and rv wire:

1: bv wire is a hard wire, more used in home improvement, rv wire when soft wire, home improvement generally does not use soft wire.

2: The voltage level is not the same, the general BVR voltage level is higher, RV is 300/500V or 450/750V, BV is 300/500V or 450/750V.

3: The implementation standard is not the same, the implementation standard of bv wire is GB/T5023-2008, and the implementation standard of rv wire is GB/T5023.3-2008.

4: The use of different places, bv is mainly used for household lighting line connection lines, rv is mainly used for electrical connection lines.

5: The price of rv wire is more expensive than the price of bv wire.

6: The service life time is not the same, rv flexible wire is easier to oxidize, so the wire placed in the circuit for a long time, the life of bv hard wire is longer than the use of rv flexible wire.



bv wire and rv wire have similarities:

The bv wire and rv wire are single-core cloth wires, the insulation material is polyvinyl chloride, both have no jacket, and the voltage classes are 450/750V and 300/500V.

What are the advantages of bv wire compared to rv wire:

1: Whether it is threading or making wire connectors, bv wire is better to operate. In addition, when making connectors or wiring terminals, rv as a flexible wire often does not burr well, resulting in short circuit or leakage.

2: The tensile strength of the rv wire is better than that of the rv wire.

3: rv wire because it is composed of multiple strands of thin wire, the resistance of each strand is relatively large. The rv wire is a single conductor, so in household circuits, the current carrying capacity and heat resistance of the rv wire are higher than that of the rv wire.

bv wires are generally single-core hard conductor sheathed wires, which are suitable for cables and wires used in power plants, household appliances, instruments and telecommunications equipment with AC voltage of 450/750V and below. RV wires are widely used in the field of industrial power distribution, especially in flexible installation sites with strict requirements, such as electric control cabinets, distribution boxes and various low-voltage electrical equipment, which can be used for the transmission of power, electrical control signals and switching signals.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
