Application of BVR Copper Wire

This product is suitable for AC rated voltage 450 / 750V and below, requiring the use of fire-retardant occasions of electrical, instrumentation, telecommunications equipment, power equipment and lighting lines fixed laying.

Features of BVR Copper Wire

The long-term permissible operating temperature of all types of cables shall not exceed 70 ℃. The laying temperature of the cable shall not be less than 0 ℃. The outer diameter (D) is less than 25 mm cable allowed bending radius should not less than 4D. The outer diameter (D) of 25mm and above the allowable bending radius of cable should not be less than 6D.




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
