Let's learn what BVR wire means and what BVR wire and cable specifications are.
What does BVR wire mean? BVR stands for copper-core PVC insulated flexible wire. Below, Kexun Cable explains BVR wire and cable specifications in detail. We hope this helps!
BVR wire is a type of flexible wire specifically designed for distribution cabinets, also known as secondary wire. It uses copper-core PVC insulated flexible wire and is used in applications requiring flexibility for fixed wiring. It is popular among electricians and architectural decorators.
What does BVR mean for national standard wire?
BV, BVV, BVVB, and BVR power cables:
Simply put: VV in electrical wiring terminology refers to two layers of polyvinyl chloride (PVC).
BV is a single-core PVC-insulated copper wire.
BVV is a two-core PVC-sheathed copper wire.
BVVB is a three-core PVC-sheathed copper wire.
BVR is a copper-core PVC-insulated flexible wire and is used in fixed wiring applications requiring flexibility.
When people ask about common wires, the BV, BVR, RV, and RVV models on the market are not those large-section cables used in construction projects.
The B series is classified as cloth wire, so it starts with a B. Voltage: 300/500V.
V stands for PVC (polyvinyl chloride), also known as plastic.
L is the code for aluminum conductor.
R stands for "soft." To achieve softness, the number of conductors is increased.
BV is copper-core PVC insulated wire.
BLV is aluminum-core PVC insulated wire.
BVR is copper-core PVC insulated flexible wire.
The above wire structure: conductor + insulation.
Take 2.5mm² as an example:
BV has two types: one with a 1.78mm diameter and seven with a 0.68mm diameter.
BLV has one with a 1.78mm diameter, and BVR has 19 with a 0.41mm diameter.
RV copper-core PVC insulated flexible connecting wire is softer than BVR, and 2.5 has 49 0.25mm copper wires.
RVV copper-core PVC insulated PVC sheathed flexible connecting wire has an additional plastic sheath compared to RV.
Also: the most commonly used "sheathed cable."
BVVB copper-core PVC insulated PVC sheathed flat cable is simply two BV wires with a white sheath.
