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
