1, the conductor structure is different. RV has thinner conductors and more conductors.
2. Different voltage levels. Generally speaking, the voltage level of BVR is high.
3. Insulation thickness is different. BVR insulation is thicker.
4. Different uses. RV is mainly used for wiring household appliances, while BVR is mainly used for motors, power distribution cabinets and other places.
The extended data BVR line is suitable for the fixed laying of power equipment with rated AC voltage of 450/750V and below. Such as home improvement lighting. Fixed wiring can be used for indoor outdoor applications, pipeline crossing and other occasions. In order to facilitate the difference in the installation process, it is divided into seven colors: red, yellow, blue, green, black, white and double * * *. Because BVR is soft-structured, its application scope is mostly in soft environment. The only difference between BVR line and BVR line is that the conductor diameter of R line is soft copper wire. That is, increase the number of conductors and reduce the diameter of a single conductor, which is less than1mm. In this way, the BVR line is very soft, and the laying angle requirement is greatly reduced compared with the BVR line. Pipe threading and trunking are more convenient and faster, which reduces labor intensity and greatly improves work efficiency.
