Abbreviated as PVC copper wire, the full name is copper core PVC insulated cloth wire. 'B' represents the category as cloth wire, while 'V' indicates that the insulation is PVC. It is suitable for power devices, household appliances, instruments, and telecommunications equipment with an AC voltage of 450/750V and below.

The BV line is divided into: ZR-BV and NH-BV.

ZR-BV: Copper core PVC insulated flame-retardant wire: The insulation material is added with flame retardants, which do not ignite when away from an open flame. The flame-retardant BV wire is further divided into three grades: A, B, and C, with grade A being the best, and so on. The most commonly used is ZR-BV.

NH-BV: Copper core polyvinyl chloride insulated fire-resistant wire: It can still be used normally under normal fire conditions.

Commonly used BV wire colors include: red, yellow, blue, green, black, white, dual color (yellow and green), and brown.

Usage: General purpose single-core rigid conductor unarmored electrical wires, suitable for alternating voltage of 450/750V and below, used for power devices, household appliances, instruments, and telecommunications equipment.

Model name:

1.Classification and usage are used for distributing current and belong to the category of wiring, represented by the letter 'B';

2.The conductor material is copper, indicated by the letter 'T', and the copper core conductor is omitted from the representation.

3.The insulating material is polyvinyl chloride, represented by the letter 'V';

4.The structure of fabric wires is simple; in addition to the three points mentioned above, some also have a sheath, with the sheath material indicated by the letter 'V' if it is made of polyvinyl chloride, and 'X' if the sheath material is rubber.

For example, BVV indicates a round wire with a copper core, PVC insulation, and a PVC sheath.

The BV line is divided into: ZR-BV and NH-BV.

ZR-BV: Copper core polyvinyl chloride insulated flame-retardant wire: The insulating material is added with a flame retardant, and it will not ignite on its own when away from an open flame.

NH-BV: Copper core PVC insulated fire-resistant wire: can still be used normally in case of fire.

BV soft wire is represented by BVR, BV rubber copper wire is represented by BX, BV rubber aluminum is represented by BLX, and BV plastic aluminum is represented by BLV.
