What is BVVB cable?
BVVB cable stands for copper-core PVC-insulated, PVC-sheathed flat cable. It is typically composed of two BV wires, each covered in a white sheath. The first letter "b" represents fixed wiring, meaning a Class 1 rigid conductor. The first letter "v" represents the insulation material of the wire, meaning PVC. The second letter "v" represents the sheathing material, and the second letter "b" represents the wire type, meaning flat cable. BVVB cable is generally suitable for indoor exposed wiring, running directly against walls for a more aesthetically pleasing effect.
What is RVVB cable?
RVVB stands for copper-core PVC-insulated, PVC-sheathed flat power cable. The "r" stands for flexible cable, the first "v" represents the insulated PVC, the second "v" represents the insulated PVC, and the "b" stands for flat. RVVB is generally suitable for household appliances, lighting, security monitoring cables, and other applications.
What is the difference between BVVB and RVVB wires?
(1) BVVB wire is two BV wires.
(2) BVVB wire has the characteristics of saving installation control and installation costs.
(3) The allowable long-term operating temperature of BVVB flat sheath line is 90℃, and the allowable long-term operating temperature of BV line is 70℃
(4) BVVB has good bending performance and can be used for mobile laying. Its service life is longer than RVVB wire.
(5) When there are more conductors, its heat dissipation performance is better than RVVB.
(6) The current carrying capacity is different. The current carrying capacity of BVVB wire is greater than that of RVVB wire.
When choosing wires, you should buy wires according to your needs. Wires of different specifications have great differences in use and are used in different occasions.
