Bvv wire and cable

The full name of bvv cable is copper core PVC insulated PVC sheathed round sheathed cable, also known as light PVC sheathed cable, commonly known as hard sheathed cable, which is a kind of sheathed cable. BVR cable is a kind of copper core PVC insulated flexible cable, which is used in occasions where flexible wiring is required. BVV cable is also known as copper core PVC insulated PVC sheathed round sheathed cable, also known as light PVC sheathed cable, commonly known as hard sheathed cable, It is a kind of sheath wire.

Bvv cable characteristics

Generally speaking, the allowable working time of this kind of wire should not exceed 65 ℃. If it is short-circuited, the maximum duration should not exceed 5 seconds. When it is laid in a concealed way, the temperature should not be lower than 0 ℃. This kind of wire has good corrosion resistance, moisture resistance and aging resistance. It can be used as a distributed current. Because it belongs to wire distribution, it is represented by the letter b. With the letter v, it indicates that it is PVC insulation material. This kind of sheathed wire is suitable for residential or commercial buildings, and some are used in the fire protection system because of its flame retardant characteristics to prevent the spread of secondary fire.

Difference between bvv cable and bvr

Bvr is a kind of flexible wire, which is composed of multiple conductors, with insulating layer but no protective layer. While bvv is hard wire, with insulating layer and protective layer, so bvr is generally used for electrical connection, and bvv is used for open wire laying.
