Material classification:
1) Copper (aluminium) conductor PVC insulated wires (BV)
2) Copper conductor PVC insulated flexible wires (BVR)
3) Copper (aluminium) conductor PVC insulated PVC sheathed round wires
4) Copper (aluminium) conductor PVC insulated PVC sheathed flat wires
5) Copper conductor PVC insulated flat and flexible connectors
6) Copper conductor PVC insulated PVC sheathed round and flexible connectors
Application:
1.Fixed occasions, home wiring(BV). 10 square mm and above specifications are composed of 7 copper wires, which are commonly used in fixed places and are commonly used in home wiring.
2.Temporary occasions, activity electricity(BVR). By 7 or more copper wire twisted, because the line is soft, mostly used for temporary places or activities of electricity, installation drag and drop and easy to move.
3.Decorative wire(BVVB). It is composed of 2 or more BV wires and is mostly used as decoration.
