XSD Tell You, Bv And Bvr Wire What Is The Difference

In the middle of the renovation of the materials used very much, such as wire, for example, you seriously to understand the words you will find the original wire specifications material is very much, take bv and bvr line, do not understand people also think that is the ordinary household wire, in fact, the difference between the two is very big, then bv and bvr line what is the difference? Let's discuss it together.

What is the difference between bv and bvr wire

1, The difference in hardness, bv wire is usually a single-core copper wire, will be harder, bvr wire is a multi-core copper wire, softer.

2, The difference in power, bv wire is a single-core line, suitable for use in the 450-750 volt range, bvr wire voltage can reach about 500 volts.

3, The difference in capacity, in the case of the same cross-sectional area of the two lines, bvr line capacity is much higher than the bv line, and withstand greater power.

Bv line advantages and disadvantages: high hardness, suitable for use in some of the more concealed construction circuit environment, the use of a long life, and is not easy to be oxidation and aging conditions.

Disadvantages: If the wire is bent and folded, it is more difficult to restore the original, and will be bent after the wire is easy to wear, so the circuit is prone to failure.

Advantages: this wire is very soft, especially for bending the project wiring, not easy to break, and the operation is very simple.

Disadvantages: because the wire is soft, so the service life will certainly be much lower, and the use of the environment is more humid, it is very easy to oxidation.

What are the skills to buy wire

1, Look at the packaging, the regular company factory wire will be clearly marked on the packaging product specifications manufacturer name and product information, and national regulations must have 3C certification of the wire.

2, The wire of copper core gloss to the amount, not white or dark, cross-sectional and insulation distribution is uniform, there can not be some insulation layer thickness is not the same.

3, The appearance of the wire insulation, which relates to our use of security, insulation is not easy to conduct electricity, and flame retardant must be good.

Summary: the above is about bv and bvr line what is the difference between the content of the points, if you want to know more about the knowledge, it is recommended to pay attention to Dongguan XSD Cable.
