How To Choose The Home Furnishing Wire? BV Or BVR?

What is the difference between BV and BVR wire?

BV and BVR wire is the same material, are copper-core PVC insulated wire, but BV wire is a harder single-core hard wire, BVR is a softer multi-core soft thin wire, the same area of the same withstand the same current.

The difference between bv wire and rv wire

BV wire:

Bv wire is generally known as a common household wire, that rv wire is what line? bv wire and rv wire between the difference is what?

Firstly, bv line, rv line naming meaning

bv: copper core polyvinyl chloride insulated wire

rv: polyvinyl chloride insulated connecting flexible wire

Secondly, bv wire and rv line structure

Bv wire and rv wire structure is the same, very simple, the conductor material are copper.

1, Bv is a single-core hard wire, 6 square below a conductor, starting from 10 square 7. BV conductor whether single-core or stranded body, relatively hard, single core is also thicker!

2, Rv is a lot of cores of soft wire, like a hair so thin, very soft. Conductor cross-sectional area ranging from 0.5 square to 10 square, mainly used for a variety of equipment within the connection line. As you can see, the structure, bv wire and rv wire is the same, Bv wire conductor for a single copper wire, rv wire conductor for multiple fine copper wire hinged together.

Advantages: because the line is harder, long life, not easy to oxidation, generally used in concealed projects.

Disadvantages: the wire is bent and difficult to straighten, repeatedly bent and straightened easily injured.

BVR wire, also called secondary wire

Advantages: the line is soft, mostly used in temporary power places, the requirements for laying angle is greatly reduced, suitable for turning through the pipe.

Disadvantages: short life, oxidation speed, easy to break the core, local heating, etc. need to be replaced in a timely manner.

Considering the circuit in the concealed line laying is a concealed project, so generally preferred to longer service life of BV wire.

Yellow, red two for the BV wire, yellow and green for the BVR line

Thirdly, the use of bv wire, rv wire

BV: long-term allowable temperature of 65 ° C, temperature -15 ° C, working voltage AC 500V, DC 1000V, fixed laying in indoor and outdoor, can be laid in the open or concealed.

RV: the use of temperature 65 ° C, the use of temperature -15 ° C, working voltage AC 250V, DC 500V, used as the internal wiring of instruments and equipment.

In short, rv line is more suitable for special environments such as more bends, or threading environment more complex occasions, bv line for general applications.

In summary: BV cable wire is hard wire, generally suitable for fixed objects that do not often move, BVR cable wire belongs to a slightly softer line, RV is more thin and soft and more with a combination of thin copper wire made of wire, generally suitable for small and medium-sized appliances, this article is for reference only, if you have questions, please contact our engineering staff.
