Model of BVR Copper Wire
The insulation materials and sheath materials of BVR copper wire is PVC. BVR copper wire according to the different properties, the product can be divided into insulation, flame retardant, fire-resistant three categories, different uses of different categories:
Model | Designation | Use occasion |
| BVR | Copper Core PVC Soft Wire | Power, electrical instruments and automation devices |
| ZR-BVR | Copper Core PVC Flame-retardant Soft Wire | With a fire-retardant requirements of electrical, instrumentation, telecommunications equipment, power equipment and lighting lines fixed laying. |
| NH-BVR | Copper Core PVC Fire-resistant Soft Wire | Control, monitoring circuits, power, line protection and other occasions, as well as large-scale construction, petroleum, metallurgy, chemical industry, cable, ship, personnel-intensive industries have higher flame retardant and fire resistance requirements |
