BV wire is widely used in power systems, household appliances, instruments, and telecommunications equipment. In home installations, it is commonly used for connecting lighting fixtures, outlets, air conditioners, and other electrical appliances.
The differences between BV wire and BVR wire are:
From the production process, BV is single-core, while BVR is multi-core. In terms of manufacturing, BVR is slightly more complex than BV.
In terms of performance, BV is essentially the same as BVR, but BVR is slightly heavier in weight.

The differences between BV wire and BVR wire are:
BVR wire, depending on the material used, is also categorized into flame-retardant wire (ZR-BVR), fire-resistant wire (NH-BVR), and low-smoke halogen-free wire (WDZ-RYJ). Users can flexibly choose according to their application. The low-smoke halogen-free wire produces minimal smoke during flame combustion, and the released gas does not contain halogen (low halogen) elements (low toxicity). During a fire, it can significantly reduce harm to instruments and equipment, thus it is widely used in high-rise buildings, large libraries, stadiums, disaster command and control centers, stations, civil airports, passenger waiting halls, key cultural heritage sites, underground shopping malls, and densely populated public places.

The differences between BV wire and BVR wire are:
Pricing-wise, BVR is slightly more expensive than BV due to its specific manufacturing process. As for electrical specifications, the range of BVR is from 2.5 mm to 70 mm. However, in line with our country's actual needs, it is the same as BV.

BV Wire: Offers insulation in various colors, suitable for fixed electrical wiring installations. It features a simple structure and wide application range.
BV soft wire is denoted as BVR, BV rubber copper wire as BX, BV rubber aluminum as BLX, BV plastic aluminum as BLV, fire-resistant BV wire as NH-BV, and flame-retardant BV wire as ZR-BV.
