Many newcomers to the wire and cable industry find it difficult to distinguish between BVR and RV cables. Even some dealers struggle to tell the difference. Because both types of cable are flexible, small gauge cables can be difficult to distinguish visually. I'd like to take this opportunity to summarize the similarities and differences between the two.
Similarities:
1. Both types of cable are flexible, consisting of multiple strands of copper wire and are called PVC insulated flexible cables.
2. Both types have a simple structure, consisting of a conductor and PVC insulation.
3. Both types come in a variety of colors, including red, yellow, black, and blue.
Differences:
1. Standards: The product standard for BVR cables is GB/T 5023.3-2008, while the product standard for RV cables is GB/T 3956. Category 5
2. Voltage: BVR wire is a type of wiring cable, generally rated at 300/500V. RV wire, on the other hand, is often used as a power supply cable within machinery and has higher voltage requirements, ranging from 450V/750V to even higher, 600/1000V.
3. Application: BVR wire is often used as wiring cable for fixed wiring where flexibility is required. It can often be used in place of BV wire, as it is softer. RV wire is often used for internal connections within various electrical appliances or machinery, and is also frequently used in security equipment and instrumentation. Therefore, RV wire is softer, hence the name "electronic wire."
4. Temperature: The maximum operating temperature of conventional BVR wire is 70°C, while that of RV wire is 80°C. Of course, high-temperature-resistant varieties are available for special requirements.
5. Appearance: The two types differ in appearance. First, BVR wire is softer than RV wire. Second, the copper wire in BVR wire is thicker than that in RV wire, which explains its softer nature.
