What kind of wire is used for decoration? The difference between BV wire and BVR wire and decoration wiring

In the decoration, the wire is an indispensable building material. So, what wire is used for decoration? There is no small matter in safe use of electricity, and the quality of the wires directly affects the safety of our daily use. Here to introduce to you, the difference between BV wire and BVR wire and decoration wiring.

The difference between BV wire and BVR wire

BV wire:

Chinese name: copper core PVC insulated wire, which is a single-strand copper core hard wire composed of a hard copper wire. When multiple copper wires are used at the same time, it is difficult to bend due to high hardness, so it is suitable for wall penetration. Walking straight, not suitable for turning through the tube. The colors of commonly used BV wires are: red, yellow, blue, green, black, white, two-color (yellow, green), brown, and the like.

BVR wire:

Chinese name: copper core PVC insulated soft sheathed wire, multi-core flexible wire, BVR wire is composed of multiple thick and thin copper wire. Wire structure: PVC insulated + soft copper wire conductor.

The only difference between a BV wire and a BVR wire is that the R wire conductor is a soft copper wire. That is to increase the number of conductors and reduce the diameter of a single conductor. In this way, the BVR wire is very soft, and the threading pipe and the wire groove are more convenient and quick, and are suitable for turning and pipe.
