BVR wire is a type of soft wire specialized for distribution cabinets, also known as secondary wire. Copper core polyvinyl chloride insulated flexible wires are used in situations where flexibility is required for fixed wiring. Highly favored by electricians and building decorators.

Product features
01. This product is suitable for fixed installation of power devices with rated AC voltage of 450/750V and below. Like home lighting. Fixed wiring can be used for indoor exposed laying, conduit installation, and other occasions.
02. For the convenience of distinguishing during installation, it can be divided into seven colors: red, yellow, blue, green, black, white, and double. Due to its soft structure, BVR is also widely used in soft environments.
03. Electric wires have good electrical insulation performance. The difference between BVR wires and BV wires is that the conductor diameter of R-type wires is soft copper wire. Namely: increase the number of conductors, reduce the diameter of a single conductor, and ensure that the diameter of a single conductor is less than 1 millimeter. In this way, BVR wires are very soft, and the laying angle requirements are greatly reduced compared to BV wires. It is more convenient and fast to thread through conduit and wire trough, reducing work intensity and greatly improving work efficiency. Highly favored by electricians and building decorators!

The difference between BV line and BVR line
1. In terms of production technology, BV is single core, while BVR is multi-core. In terms of production, BVR is a bit more complex than BV.
2. In terms of price, BV and BVR are slightly more expensive than BV due to their limited craftsmanship. According to the International Electrotechnical Commission, the range of BVR is from 2.5 mm to 70 mm. However, according to the actual needs of China, it is the same as BV.
3. In terms of performance, BV and BVR are basically the same, but BVR is slightly heavier in weight; Similarly, BVR wires are divided into flame-retardant wires (ZR-BVR), fire-resistant wires (NH-BVR), and low smoke halogen-free wires (WDZ-RYJ) based on the selected material. Users can flexibly grasp according to the usage situation. Among them, low smoke and low halogen wires generate a very small amount of smoke under flame combustion, and the released gas does not contain halogen (low halogen) elements, which is non-toxic (low toxicity). When a fire occurs, it can greatly reduce the harm to instruments, equipment, and human health, and is therefore widely used in high-rise buildings, hospitals, large libraries, sports venues, disaster prevention command and dispatch buildings, stations and civil airports, passenger waiting rooms, key cultural relics protection sites, as well as subways, underground shopping malls, or densely populated public places.
