We all know that wires and cables come in different sizes and models. BVR wire and RVV cable fall under this category. Many people ask what the difference is between BVR and RVV cables. Every product has its own set of comparisons. One thing everyone needs to understand clearly is that the two types of wire are fundamentally different.
1. BVR Wire
BVR wire's Chinese name: Copper Core PVC Insulated Soft-Sheathed Wire. Wire Structure: Conductor + Insulation
Detailed explanation of each letter: B stands for wiring (for example, for indoor power lines, nailed to the wall). Voltage: 300/500V. V stands for PVC plastic sheath (one V represents single layer insulation, two Vs represent double layer insulation). L stands for aluminum wire; no L indicates copper wire. R stands for flexible wire. To achieve flexibility, the number of conductors is increased and the diameter of each wire is reduced. Structure: The conductor is copper wire, with an average diameter of less than one millimeter.
RVV (Copper Core PVC Insulated, Polyvinyl Chloride Sheathed) Flexible Wire, also known as Lightweight PVC Sheathed Flexible Wire or Soft Sheathed Wire, is a type of sheathed wire. Rated voltage: 300V/500V. Core counts range from 2 to 24, color-coded according to national standards. Cables with two or more cores are twisted together, with the outer layer twisted in a right-hand direction. They are widely used in control installations for instruments, meters, building intercoms, and surveillance systems.
Differences between BVR and RVV Wires
1. Material: BVR is a copper core PVC insulated flexible wire primarily used for home renovations and general electronic instrument installations; RVV is a sheathed insulated cable widely used in control installations for instruments, meters, and other equipment.
2. Structure: BVR is a single-core wire composed of multiple copper wires, with only insulation and no sheath. RVV is also composed of multiple copper wires, but can be multi-core, with both insulation and a sheath.
3. Application: BVR is primarily used for home renovation and general electronic instrument installation; RVV is more suitable for internal cable connections and signal transmission in instrumentation.
The differences between the two are readily apparent. Whether purchasing or gaining industry-related knowledge, this list provides a simple reference for those unfamiliar with wire and cable.
